1.4.2 Low-battery alarms
The IQ Force is equipped with a rechargeable Lithium-Ion (Li-Ion) battery. The IQ Force includes multi-staged low-battery alarms to let the user know that the battery is running low. For detailed information concerning the low battery alarms, see Section 2.4.5
1.4.3 Sensor over-range alarms
The IQ Force will go into alarm if a sensor is exposed to a concentration of gas that exceeds its established range. In the case of an LEL reading that exceeds 100% LEL, the LEL channel will be automatically disabled by the instrument and the instrument will remain inconstant alarm until it is turned off, brought to an area that is known to be safe, and then turned back on. The display will show “OL” (over limit) or ERR if the LEL sensor has gone over range and “OL” for all other sensors that have gone into over range alarm.
See Section 2.4.6
for further details on sensor over range alarms.
