Responding to over range alarms
WARNING: An over range condition may indicate an extreme toxic gas or oxygen
content condition. Confirm a normal condition with a different GasWatch
or other gas detection device.
1. Determine which sensor is initiating the over range alarm.
2. Calibrate the sensor as described on page 9.
3. If the over range condition continues, replace the sensor as described on page 12.
4. If the over range condition continues after you replace the sensor, contact RKI
Instruments, Inc., for further instruction.
Responding to battery alarms
WARNING: The GasWatch is not operational as a gas monitoring device during a
battery failure alarm. Take the GasWatch to a non-hazardous area, and
replace the battery as described on page 12.
The GasWatch is fully functional during a low battery alarm; however, the GasWatch has
approximately 10 minutes of operating time remaining from the initial low battery alarm.
Replace the battery as soon as possible as described on page 12.
NOTE: Other alarms and use of the back light feature reduce the amount of operating
time remaining.
