Return to level 1
New sensor calibration
New sensor calibration
Activate calibration,
Apply calibration gas
Note: This operation sets
nr. of calibrations to
1 and redefines
sensor mV reference
when successful

Terminate menu
Slow Flash (2/sec)
“10 sec Menu Timeout in progress”. This timeout starts 30 sec after the last menu selection was made.
Apply magnet to re-enter at Level 1. The analogue output remains at calibration level in this mode.
If magnet not applied, the instrument will write menu parameters to EEPROM,
exit menu and revert to normal operation following timeout.
