3.1.1 Alarms

Audio and visual alarms will activate in pulsed or continuous, to indicate the type of alarm being triggered. The display will

indicate the threshold or code of the alarm. To clear a threshold alarm after leaving the dangerous area, press and release the

ALARM

switch.

OTE

: If the alarm threshold is still exceeded: The visual alarm will continue to flash and the threshold pictogram will remain

indicated.

Fault alarms are not able to be cleared, see fault alarms table for possible remedies.

Threshold Alarms: Pulsed audio alarm can be cleared by pressing the

ALARM

switch

Display Possible Cause Possible Remedy

Display: BAT

Batteries discharged:

The instrument can no longer operate

Turn instrument off and recharge the

batteries

Display: SUP Measurement range is exceeded Leave contaminated area and allow

sensor to stabilize in clean air.

1DEF The cell zero has drifted out of spec Calibrate

2DEF The cell is too sensitive Calibrate

4DEF (on small digits) Expired Cell (sensitivity too low) Replace cell and calibrate

8DEF

The EE

PROM

of the instrument is not

initialized

Return to ENMET for initialization

512DEF Problem in the calculations, capacity

exceeded

Return to ENMET

16DEF Measurement to negative Calibrate

May need to replace cell and calibrate

64DEF Temperature sensor is damaged Return to ENMET

Er45 or Er49 Communication error between the

microprocessor and the cell EE

PROM

• Disconnect the cell and check the

connection.

• Replace cell if message persists

• Return to ENMET

OTE

: If several faults are simultaneously present, the display corresponds to the sum of faults.

Example: The messages Er 35 or Er 39 show the communication errors between the microcontroller of the apparatus and

the EE

PROM

memory of the device.
