Detector Operations

Activate the detector

Turn-on the detector in a safe area with an atmosphere of
20.9% oxygen and free of hazardous gas.
1. For first time use, charge the battery for up to 8 hours
or until LED light turns green using the charging
adapter provided. Refer to Charge the battery for more
information.
2. Press and hold the button for three seconds.
3. For first time use, a Warming sensors message is
displayed and a 30 minutes countdown is displayed.
In most cases, this countdown only lasts a couple of
minutes.
4. When the detector displays Pump test Block inlet,
block the pump inlet with a finger, and then after a
couple of seconds unblock the pump inlet.
The detector performs a quick pump test. A Pump Test
passed message is displayed.
If you do not block the pump inlet, the detector will turn
off after two minutes.
The detector will then perform a self-test, including
testing the sensors. This process could take several
minutes.
If necessary, you will be instructed by screen prompts to
calibrate newly-installed sensors.
5. When the self-test is complete, press and hold the
button to zero sensors. After the autozero is complete,
the detector then checks the sensors for calibration and
bump test.
If the detector identifies sensors requiring calibration or
bump testing, press the button and follow the on-screen
instructions.
