Startup: Presetting required —> before first calibration and when changing sensor
Presetting: Connect digital voltmeter to MAI card jacks.
Bridge current setting —> 270 mA/300 mA only for methane
Zero adjustment by zero gas —> Zero setting to Ua = 400 ... 450 mV
Sensitivity adjustment with measuring gas —> Measuring range level
Ua = 1950 ... 2100 mV
or by means of the value of the existing gas concentration according to:
Ua (mV) = C (Span gas concentration in % of measuring range) / 100
*
1600 + 400
Warm-up period: ≤ 60 s according to EN 50054, 15 minutes for presetting, 2 hours for calibration
Function test: Span gas application via: PK10 with 1.0 l/min
or PV10 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.
