4.2 Digital Display Codes
The following codes will appear on the dis-
play when the unit is placed in a mode other
than the normal operating mode.
SU Start-Up
- - (steady) Magnetic Switch Activated
- - (flashing) Test Gas Mode
AC Automatic Calibration
CP Calibration in Progress
CC Calibration is Complete
F1 Failed to Zero during calibration
F2 Failed to complete the calibration
F3 Failed to Span during calibration
F4 Sensor Reference Bead Error
F5 Sensor Active Bead Error
F6 Low Supply Voltage
F7 EEPROM Verification Failure
F8 Negative Zero Drift
F9 Calibration check period exceeded
When the unit is in the normal operating
mode, the display will indicate the presence of
combustible gas in percent of the Lower Ex-
plosive Level (% LEL). The range of detec-
tion is from 0 to 99% LEL.
99 (
flashing) Over-Range, a gas concentration
exceeding 100% LEL is present.
SU This is displayed for about fifty seconds
during start-up and after a Fault condition
has been corrected.
- - Appears on the display when the magnet
has been properly positioned over the
GMI Logo and when the Test Gas
Mode can be or has been entered.
