2 W A R N I N G Safety is of utmost concern to Watthour Engineering Co., Inc. The operator should become familiar with the care and use of the Model 3010 PAT by reading this manual before attempting to use the device. Because of the dangers associated with exposed voltages when making "on-site" meter tests, extreme care should be taken when testing. Watthour Engineering Co., Inc. does NOT recommend the testing of 480 volt meters at a customer's location. Although the Model 3010 PAT has the capability of testing with 480 VAC output, the auto-ranging input (supply) is limited to 300 VAC max. When taking "on-site" measurements in the "READ" mode, it is very important to avoid opening a secondary current transformer (CT) circuit. High and potentially lethal voltages could be exposed, if the current circuit is opened. Read the tutorial "Read Mode Operation" carefully. DO NOT POWER THE TEST KIT WITH VOLTAGE ABOVE 300 VAC. Also provided is a front panel safety grounding post to allow the PAT test kit chassis to be tied to a secure ground point at the meter test location. MAKE THIS CONNECTION FIRST! Watthour Engineering Co., Inc. assumes NO liability from misuse or negligence on the part of the test kit operator. Watthour Engineering Co., Inc. Pearl, Mississippi USE THIS EQUIPMENT SAFELY!!

8 1.0 MODEL 3010 PRINCIPLE OF OPERATION The Model 3010 Meter Test System is a portable KWH comparator and KW demand testing unit. The Model 3010 is of modular construction and is designed to test both A-base meters and socket meters with the proper adapter. Refer to the block diagram on page five for additional information. The internal power supply takes the VAC source input voltage and converts it to deliver ±25 VDC to the solid state loading board, and the power op/amp boards. It also delivers ±25, ±15, and +5 VDC to the CPU board and ±15 and +5 VDC to the solid state loading board. The solid state loading board contains the microprocessor which sends four digital signals (one for the voltage channel, one for the left current channel, one for the center current channel, and one for the right current channel) to four digital to analog generators. These generators produce stepped analog signals which are then sent through four filters ( one for each channel ) to produce a clean sine waveform. These waveforms are then sent through four magnitude DACs which produce four usable sine waveforms which are then sent to the four power amplifiers. The power amps use the ±25 VDC voltage from the power supply to produce a 0-30 VAC output. The AC output on the voltage channel is routed to a voltage power transformer. This voltage is then routed to the solid state loading board (which produces a VAC output) and then to both the Radian standard and the meter under test. The AC outputs from the three current channels are applied to current transformers. This produces a amp output which passes through Hall effect current sensors. The three current channels are routed to the Radian standard, and on to the meter under test. A Radian standard is used to measure the energy produced by the test kit. Depending on which standard is installed the test board can measure KW hours/ KW, KQ hours/ KQ, and KVAR hours/ KVAR. (The customer should specify which standard is needed at the time the unit is ordered.) The data output from the Hall effect sensors is sent to two analog to digital converters (ADC). One of these converters measures volts and amps, and the other measures phase angle. The digital output from the ADCs is sent along an 8 bit parallel interface path to the microprocessor and the CPU board. The CPU receives the input from the optical reflect mode probe or the solid state probe and the pulses from the Radian standard to produce an eight bit data output which is sent to the CPU. The CPU sends accuracy information to the liquid crystal display. Rev 1.3 7

16 3.0 CONTROLS AND FUNCTIONS 3.1 FRONT PANEL 3.2 TEST / ELEMENT / METER TYPE BLOCK 3.21 The TEST input key allows the operator to set up for full load, light load, power factor, or the creep test mode of operation. To select the desired test the operator simply depresses the TEST key until the LED for the desired test is illuminated The ELEMENT input key allows the operator to select series, left, center, or right current elements. Only valid current elements for the meter form set up in the Model 3010 may be selected. For example a form 5 meter does not have a center current element therefore the test board will only scroll through the series, left, and right current elements The METER TYPE input key will select the type meter to be tested. The Model 3010 is normally supplied with a Radian Research RM or -02 standard. As an option, the unit can be supplied with a Radian Research RM or RM standard to allow VAR and Q hour meter testing. Depressing this key selects either KWH meter testing, VAR meter testing, or Q meter testing. The normal default phase angles for power factor will be used during VAR and Q hour PF tests. Rev

17 3.3 COM PORTS BLOCK The surface mounted RJ-11 connectors located on the front panel of the 3010 provide connection to communication ports 1 and 2. Com Port 1 allows connection to a modem/intelligent interface device. This communications port is designed to fully integrate into the total system environment provided through the WATT-Net local area network. With this software package, downloading meter test data as well as meter record keeping information to a host computer can be accomplished. The WATT-Net LAN capability provided through this port is fully hardware and software compatible with all Watthour Engineering Co., Inc. products. Com Port 2 is used to provide a serial interface to a printer or bar code reader. 3.4 DISPLAY CONTROL BLOCK This block contains the contrast and back light controls for the LCD computer display. The solid state electro-luminescent backlight may be turned on or off at the operators discretion as ambient light requires. Likewise the contrast of the LC display may be adjusted by pressing either the up or down arrow keys. Depressing the key once will make one step change to the contrast. 3.5 TEST CONTROL BLOCK The functions in this block provide the ADJUST OPTICS, START, AUTO- SEQUENCE, CANCEL, SAVE TEST AND TEST MODE selections allowing for the start and stop control of tests. The TEST MODE key selects between KWH mode of testing or demand mode testing. The key is depressed to select the desired test and indicated by the LED. 3.6 GATE CONTROL BLOCK The gate control input connector allows connection of the optical detector for the reflect and solid state pickup probes. The external signal used to compare standards or externally gate the test board is connected here. It is a five pin connector with a blue housing color. Rev

18 3.7 PULSE INPUT BLOCK The pulse input connections allow KYZ pulse initiator checking. In the demand test mode, the operator is allowed to select either a form A or form C contact input. These are normally associated with the type of KYZ pulse initiator device to be tested. This input will accept either a dry contact or a solid state output type of contact closure. It is a 4 pin connector with a red housing color. 3.8 AUDIO CONTROL BLOCK This control block allows the operator to set an End-Of-Test audible alert or a Pulse signal to aid in optical adjustments as desired. The audio level may be set by pressing the up or down arrow keys. A LED indicator bar displays the audio level. The audio level indicator bar must have at least one LED illuminated in order for the beep tone to be audible. 3.9 KEYPAD Meter test data may be entered via the keypad. To enter a numeric character simply press the desired number. The cursor will automatically increment to the next space after an approximate ½ second delay. If the specific field can have valid alpha character entries, press the number key associated with the desired character subsequently until the desired alpha character is displayed. If the cursor increments to the next position before the desired character is input, simply use the back arrow key to correct. The space key will blank the character in the cursors position. The right and left arrow keys will move the cursor without blanking the field. The Enter key will accept data entered from any of the 9 main menu selections and also allow the scrolling/viewing of the 9 main menu selections. The MENU/TEST key enables the TEST CONTROL block and allows testing to begin. Context sensitive help is on-line by pressing the HELP key. To exit the help screens, press the ENTER key. In the main menu portion of the test program, the operator is prompted with the on display to ENTER to scroll through the next menu. The operator may select menu numbers 1 through 9 from any main menu display screen to jump to the desired menu. Rev

19 3.10 INPUT BLOCK The INPUT block contains the main power switch used to power up the test kit. A three terminal euro connector which allows the operator to connect the main input power cord to the test kit. This AC source should be between 90 and 300 VAC. The Main Power switch is a Circuit Breaker for input protection CONNECTIONS BLOCK This block contains the connectors that enable the operator to connect to the meter under test. Care should be given not to exceed the burden capabilities of the PAT or the desired output current may not be obtained. The test leads are color coded to allow easy test set up. Normally the red current leads are for connecting the left element of the meter-under-test, the white (or gray) leads are for the center element connection to the meter, and the black leads are used for the right element connections. Polarity of the paired colors is accomplished by the colored connectors on the PAT (and the corresponding colored rubber boot on the opposite end for leads to test transformer rated meters). The black end of each connection is considered the return for current and voltage. The unit is supplied with one set of potential test leads. These are the red and black leads with the smaller 18 AWG red and black A mode connectors. NOTE: Due to the many and varied test adapters available for field testing of self contained meters, NO connectors are supplied with the self-contained current leads. You must furnish your own lead connectors. Rev

20 3.12 MODE BLOCK The MODE switch toggles between READ and TEST modes of operation. In the READ mode the Model 3010 functions as a high quality voltmeter, ammeter and a phase angle meter. In the TEST mode the PAT supplies test current potential to meters under test. In the READ mode of operation the PAT is used to read voltage, current, and phase angle. The phase angle is read as the number of degrees the current input LAGS the voltage input and indicates from 0 to 359 degrees. It is important that the test kit be powered up and switched into the READ mode BEFORE the current is connected. This is because the current circuit is open with the PAT not powered. In the READ mode, the LEFT current connection is used along with the potential connection in making phase angle measurements. It is again important to assure that the secondary of any CT circuit NOT be opened when making current readings. High and Dangerous voltages could be present in an open CT secondary condition. The voltage measurement range is from 30 to 600 VAC and the current measurement range is from.1 to 50 amps. When switching back to the TEST mode, a prompt will be shown reminding the operator to remove all test leads and press ENTER to continue. This is because the LEFT current circuit will be OPENED as the TEST mode is entered OPTICAL PICKUP ASSEMBLY The optical pickup assembly has been designed to easily slip on and off the meter-under-test while maintaining a sure grip on the meter cover. The elastic band provides a positive hold on the meter glass for the optic probe during meter tests. There is a visible red LED to aid in aligning the probe to the meter disk. The wide pickup range of the probe should allow for ease of adjustment for most meters. Should adjustment be required, a sensitivity control is located on the top of the probe (marked SENS) and may be adjusted with the small screwdriver supplied with the PAT. This is a one turn sensitivity control and can easily be damaged if forced past its limits in either direction. In most applications, the sensitivity control should not require adjustment as it has been preset at the factory. Rev
