Startup: Presetting required —> before first calibration and when changing sensor
Presetting: Connect digital voltmeter to MAI card jacks.
Bridge current setting —> 280 mA
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:
15 min minutes for presetting,
2 hours for calibration
Function test: Span gas application via: test cap with 1,0 l/ min (Order-No.: 10049316)
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 (Order-No.: D0792420)
Possible other measuring components and measuring ranges on request.
Open or Short Circuit Fault Indication:
X= Signal failure (FAIL-LED)
XX= Alarm LED‘s, Signal exceeded, Signal failure (FAIL-LED)
XXX= only alarms
