Electrical power should be supplied at 100 V to 240 Vac ± 10% - 50 / 60 Hz. No voltage range selection is required. A power on LED is illuminated when power is present at the analyser. For compliance with the EMC standards, the external earth / ground connection must always be connected to a local earth / ground. Refer to Figure (A). In addition, the connections to TB2, TB3 and TB4 must always be made using a screened or shielded cable with the earth termination being made at the cable gland. Ensure good EMC practices are observed when making connections. All electrical connections are made...

Sample and Calibration gas connection CAUTION The sample gas must not be admitted to the analyser until a period of 4 hours has been allowed for warm up, this will prevent condensation of the sample in the measuring cell. The inlet pressure and flow rate for the sample or calibration gas must not exceed the limits specified in the following table or damage could occur. Use an external pressure reducing device if necessary. When pressurising the sample system for the purpose of leak testing ensure that pressure is increased and decreased slowly. High internal flow rates created when the...
