Alarm Signals
The instrument is equipped with audible, visible, and vibration alarms. During its normal operation, the
PGM-65XX compares gas concentrations to the programmed alarm limits for Low, High, TWA and
STEL alarms. If the concentration exceeds any of the preset limits, the loud buzzer, and red flashing
LEDs are activated immediately to warn of the alarm condition. In addition, the PGM-65XX alarms if the
battery voltage is low, pump is blocked, etc.
When a low-battery alarm occurs, there may be approximately 20 to 30 minutes of operating time
remaining. However, it is recommended that you promptly change or charge the battery in a non-
hazardous location.
