CAUTION

Be sure that the Gas Concentration Unit of the instrument matches that on the Calibration 

Gas cylinder used for each sensor. Otherwise, dangerously low readings could result. Once 

calibration is complete, the units can be changed between the fi rst four on the list above and 

the readings will be correct. Then make sure that alarm limits are entered in the same units 

that are selected for the concentration readout.

WARNING

Disabeling/changing any of the alarm devices prevents notifi cation of hazardous gas 

concentrations and can lead to serious injury or death!

4.5.5 SET SPAN VALUE

To change the calibration gas concentrations, enter the Calibration menu and select ‘Span Value’. 
Update the values as need and press Done to exit and acknowledge any changes when asked to 
‘Save?’ To switch the Left soft key function from increasing to decreasing, hold both keys down 
simultaneously for about 2 seconds until 

 changes to 

 .

4.6 ALARM SETTINGS

Use this menu to change alarm limits, select alarm devices, enable a heartbeat light and enter Man-
down alarm parameters.

4.6.1 HIGH, LOW, STEL AND TWA ALARM LIMITS

In the ‘Alarm Setting’ menu, select the desired alarm type and enter the values for each sensor as 
described above in Section 5.3.3. Make sure that the concentration units of the alarm limits match 
those selected for the displayed concentration readings. Note: Some alarm limits are not applicable to 
all sensors. For example, the oxygen and LEL sensors do not appear in the list of STEL and TWA alarm 
limits.

4.6.2 ALARM DEVICE

Use this menu to select or de-select any combination of the audio (buzzer), visual (LED) or vibration 
alarms

4.6.3 HEART BEAT LIGHT

The ‘Heartbeat’ light fl ashes an LED at regular intervals to verify that the unit is still on. This is especially 
useful in high noise situations where the pump cannot be heard. The interval between fl ashing lights 
can be set between 1 and 10 seconds, or turned off  by setting to 0.
