Startup: Presetting required —> before first calibration and when changing sensor
Presetting: Connect digital voltmeter to MAI card jacks.
Bridge current setting —> 118 mA for all components
Zero adjustment by zero gas —> Zero setting to Ua = 400 ... 450 mV
Sensitivity adjustment with measuring gas —> Measuring range level
Ua = 1950 ... 2100 mV
Warm-up period: 15 minutes for presetting, 48 hours for calibration
Function test: Span gas application via: PK 10 with 1.0 l/min
or PV 10 with 1.0 l/min
Calibration: Calibration procedure according to SUPREMA operation manual
For measuring components allowed, measuring ranges, lower alarm levels and
conditions for calibration see list of components.
Possible other measuring components and measuring ranges on request.
