Move the sliding switch to position. Press the keypad (excluding the decimal point) to enter the value of directly.. Using the test leads or alligator clips, touch or clip on the terminals to be calibrated.. Because not all the frequencies are available between to, calibrator will automatically adjust and display the users input value to a frequency, which is available and always larger or equal to users input TC C V _ Note: The resolution of function is. For the range -, all the frequencies in between are available. But for the range -, not all the frequencies are available (total frequencies available). Please refer to section III Electrical Specifications for available frequencies.

16 . Thermocouple Calibration of,. a. General Operation. Turn the power on, and wait until the STBY symbol disappears (about min.).. Plug the corresponding connector (K-type connector for K-type thermocouple, J-type connector for J-type thermocouple,...) into TC terminals of calibrator and thermometer to be calibrated.. Move the sliding switch to, position. Press the keypad (including the minus - button) to enter the value of Temperature directly.. C TC C V _

17 . TC C V _ Note: Users can plug the connector into the TC terminals of calibrator even before the power is turned on for better thermal equilibrium between the TC terminal and thermocouple connector. Note: Only in the and functions, the negative values are allowed to be entered. To enter negative temperature, press the minus"-" button first. Note: Maximum digits (including the "-" sign) can be entered. If users enter less than digits ( to digits), users must press button to indicate the end of entry. If users enter or more digits, calibrator will automatically end the entry and output specified value of temperature.

18 b. Select, or Users can select or by pressing the shift button to enter mode. Then press the NUMBER button repeatedly to select desired temperature unit. After desired unit is selected, press the button again to exit the mode. Corresponding voltage or symbol will be displayed in the LCD. TC TC C C V V C

20 c. Select K, J, E, or T type Thermocouple Users can select K, J, E, or T type Thermocouple by pressing the shift button to enter mode. Then press the number button repeatedly to select desired type of thermocouple. After desired type is selected, press the shift button again to exit the mode. Corresponding thermocouple type (K, J, E, or T) symbol will be displayed in the LCD. TC TC C C V V C

22 . input in the,, V functions In the,, or V function, users can enter percentage. To enter percentage (). Users press the shift button first, then symbol will be displayed in the LCD. Press button first, then press the number (no decimal number, the resolution is ). After percentage is entered, the percentage will be displayed in the upper LCD, and the corresponding value will be displayed in the lower LCD.. The corresponding value is calculated based upon the range selected. -: =. -: =. -: =. -: = -V: =.V -: =.. To exit the percentage-input mode, press the button again.. After the button is pressed, the upper LCD will become blank, while the lower LCD retains its last value. TC TC C C V V

24 . Easy Step in the,, and V Functions While the percentage is entered and calibrator is still in the mode, users can step up or down by the percentage entered. The maximum percentage is while the minimum percentage is. If the next step up or down exceeds the maximum or minimum percentage, the percentage will stay in the previous step.

26 . Auto Ramp in the,, and V functions In the,, and V function, auto ramp function is available to the users. To start the ramp function:. Press the button to enter the mode.. Press the NUMBER key to start. Ramp function increment from to, then decrements from to repeatedly. The resolution of each step is (with respect the range selected) at an interval of. seconds. So it takes seconds to ramp from to.. To temporarily stop the ramp function, press the NUMBER key, and the output will stay at the value when the NUMBER key is pressed. These features will facilitate the checking of trigger point of tested device, such as valve controller.. To restart again, press the NUMBER button again.. To return to the regular output mode, press the button again when ramp function is stopped. TC TC C V V

35 IV. Use the AC adapter If long term usage of the calibrator is required, AC adapter can be used. The AC terminal is located in the back of the calibrator. The voltage should be regulated between to V. DC DC - +

36 V. Use External Battery Pack An external battery pack is included for a longer period usage. The external battery pack needs to be packed with pieces of. volts AA batteries. To use the external battery pack, plug into the AC terminals located in the back of the calibrator. BATTERY HOLDER BATTERIES x.v AA

37 VI. Battery Replacement When the low battery symbol is displayed on LCD, follow the following procedures to replace the battery. Turn off the calibrator by pushing the On/Off button. Remove the screw of the battery compartment cover and remove the battery compartment cover. Replace the old V battery with a new alkaline V battery. Replace the battery compartment cover and fasten the screw. - + Note: In the,, V,, and functions, status of low battery is detected. While in the function, status of low battery is not detected.
