Establishing Power to the Analyzer
The analyzer is fully operational from the shipping container with the oxygen sensor installed and calibrated at the
factory prior to shipment. Once installed, we recommend the user allow the analyzer to stabilize for 10-15 minutes
before analyzing a sample gas.
Establish power to the analyzer electronics by pushing the red ON/OFF key. The digital display responds
instantaneously. When power is applied, the analyzer performs several diagnostic system status checks termed
“START-UP TEST” as illustrated below.
If equipped with an optional integral sampling pump, it is operated by
a separate toggle switch located on the front of the analyzer. When
using the sample pump, open the flow control valve completely.
Note: In the unlikely event, the LOW BATTERY warning LED comes
on when the analyzer is turned on – proceed immediately to section 6
Maintenance Battery.
The analyzer is supplied with a 9 V AC/DC adapter for recharging the
batteries or operating the analyzer continuously. The analyzer’s
charging circuit accepts only 9 VDC from any standard AC 110V or
220V adapter (with positive supply in the center of the female
charging jack). The electronic design enables the analyzer to remain
fully operable during the 8-10 hour charging cycle. However, the
analyzer must be charged in safe areas only.
Once the power to the electronics is established, the digital display responds instantaneously. When power is applied,
the analyzer performs several diagnostic system status checks termed “START-UP TEST” as illustrated below:
START-UP TEST
ELECTRONICS – PASS
TEMP SENSOR – PASS
BAROMETRIC SENSOR – PASS

After self diagnostic tests, the analyzer turns itself into the sampling mode. And displays oxygen contents the sensor is
exposed to, the analysis range, the ambient temperature and pressure.
