Start-up Preadjustment required before first calibration and when changing sensor
Preadjustment
Connect the digital multimeter to the test sockets on the MAI module.
Bridge current
setting:
310 mA
Zero adjustment
by zero gas:
Zero setting Ua = 400–450 mV
Sensitivity adjust-
ment with
measuring gas
Measuring range level Ua = 1950–2100 mV
or with the value of the existing gas concentration
according to:
Ua (mV) = C / 100 * 1600 + 400
C = Span gas concentration in % of measuring range
Warm-up period
15 min minutes for preadjustment,
2 hours for calibration
Function test
Span gas application via:
• Test cap with 1.0 l/ min
Calibration
Calibration procedure according to chapter 7 "Calibration".
For approved gas types, measuring ranges, lower alarm levels and condi-
tions for calibration see list of components (Order No.: D0792420)
Possible other gas types and measuring ranges on request.
