8 Principal safety information Use the device only in the operating and measuring ranges specified in Technical data. Use the device only under the conditions and for the purpose for which it was designed. For this, particularly observe the safety information and the technical data. To prevent damage to the instrumentation and items under test, suitably trained persons should only use the equipment. Observe all local Health and Safety regulations before operating the test equipment. Do not make measurements on live components. Observe the warnings on the control unit and analyser box! Magnets of the control unit The magnets of the control unit can damage EC cards, telephone cards etc. Operation with mains adapter Use only the original mains adapter to operate the device. Replace damaged mains cable only with an original mains cable of the manufacturer or agent (i.e. by authorised service). Check for leaks The entire measuring system (probe, condensation trap, filter, hoses and connections) must be checked for leaks before each measurement, e.g. by pushing on a collapsed rubber bladder. Measuring errors can be caused if external air infiltrates. Expose the gas outlet When measuring, ensure that the gas outlets are exposed to allow the gas to escape unobstructed. If this is not the case, the measurement results can be falsified. Empty the condensation trap The condensation trap must only be emptied when the pump is switched off (the measuring cells are otherwise in danger of damage)! Disposing of batteries The end user is legally required to dispose of all used batteries in accordance with their country s regulations. Disposing of measuring cells Storing the analyser in rooms containing solvents, vapours or gases will damage the measurement cells e.g. cleaning fluids, polishes, paints, cooking operations. Protect the device from direct sunlight and store at temperatures <45 C. Storing the device Storing the analyser in rooms containing solvents, vapours or gases will damage the measurement cells e.g. cleaning fluids, polishes, paints, cooking operations. Protect the device from direct sunlight and store at temperatures <45 C. Charge the battery before use Before making the first measurement or after several days of disuse, fully charge the internal battery (see menu Service Operating values). Charge the battery at least every 4 weeks during longer periods of disuse to prevent damagingly low discharging. Changing the configuration Switch off the device to change the configuration (e.g. probe change), as the device reads the probe-specific values when it is switched on. PC cable connected When the PC cable is connected, it is impossible to issue a print command. Using probes with plug head Ensure the good contact of probes with plug heads. Fully tighten the union nut on the probe handle. Opening the device If the device is opened, misused or subjected to force, the warranty will be voided. Because the pressure sensor heats up, it is recommended to wait on the Warm up for 15 minutes to achieve the best possible accuracy. 8

20 Example measurement Correct use of the flue gas probe The measurement of the flue gas temperature is made by the thermocouple at the tip of the flue gas probe. The probe tube protects the thermocouple, but has openings in to allow the stream of flue gas to envelop the thermocouple. The thermocouple must always be exposed to the stream of flue gas to allow an exact measurement of the flue gas temperature and thereby a precise determination of the flue gas losses. It must not be screened by a web of the probe pipe. Flue gas stream incorrect correct The tip of the thermocouple must not touch the guard. If necessary, bend the tip of the thermocouple accordingly. The incorrect correct Thermocouple temperature measurement is made during the zeroing phase. The flue gas probe can be adjusted in the flue at this time (Note: the AT probe must be connected). This makes it possible to conduct a core current search during the zeroing phase. The temperature measured by the flue gas probe is interpreted by the testo 300 XXL as the combustion air temperature unless a AT probe is connected (Note: the probe must be removed from the flue). When the zeroing phase has been completed, this value is saved as the combustion air temperature value. All dependent parameters are calculated by this value. 20

Initialisation 10 sec Warming up phase 30 sec The measured CO2 value depends on the absolute atmospheric pressure. This effect is compensated by the device internally. For this, enter the absolute pressure of the location in the main menu. The displayed CO2 value is automatically compensated to the entered absolute pressure. The measuring principle is based on infrared absorption. This type of probe has a relatively high power consumption. For long-term measurements, use the mains adapter and rechargeable batteries. If sudden changes occur in the concentration, the probe will require sec. to adapt to the environment. Gently waving the probe reduces the adaptation time.

39 Main menu Memory Overview The memory organisation of the testo 300 XXL is designed such that a so-called Location must exist to identify a saved reading. This location can consist of up to 20 alphanumeric characters. For example, a location may be: - the name of the customer - a customer number or - the designation of a location. Several measurements can be saved for each location. This is possible by pressing the function key Mem. several times. It is also possible to place locations in directories (see Measurement data processing). The maximum possible number of measurements depends on whether each individual measurement is saved with its own location or all measurements are saved exclusively with one location. 39

The barcode pen is connected to the RS-232 socket on the bottom of the device and can be connected and disconnected whilst the device is switched on. Activate the barcode pen by holding the tip of the pen briefly against a white surface, e.g. the barcode label. Then move the pen evenly and quickly in direct contact across the barcode pattern. A correct reading is indicated by a signal tone. The location is automatically accepted in the location list of the testo 300 XXL and is selectzed as the active location. It is unnecessary to read or manually enter the customer number of the customer where you are measuring beforehand with a PC or by hand into the testo 300 XXL. When you visit a customer whose customer number is not saved in the device, you can read the number directly on site by the barcode into the testo 300 XXL. If the location read by the barcode pen already exists in the testo 300 XXL, this is activated. Note Barcodes can be created and decoded with the evaluation software. 46
