The IQ Force must be located in a nonhazardous location during
the charging cycle. The IQ Force’s battery charger is not approved
for use in hazardous locations.

Alarms
2.5.6 Sensor over-range alarms
For all gases and vapors other than oxygen, the IQ Force will go into alarm and display “OL” (over limit) 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 alarm will latch (remain on) until the instrument is turned off. The IQ Force must be turned off, brought to an area that is known to be safe (containing 20.9% oxygen, 0% LEL, and 0 ppm toxic gases, and then turned back on. The display will show “---” and “OL” alternately in place of the sensor reading for any channel that has gone into over-range alarm.
Toxic channel “OL” alarms occur when HS readings go over 200 ppm or CO readings go over 1000 ppm. When the toxic channel records below the
“OL” levels, the ppm readings return to the display. Any channel that reads and “OL” level will require recalibration.
