Establishing Power to the Electronics
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 and then recalibrate the
device as instructed below.
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.
Note: In the unlikely event the LED warning indicator LOW BATT comes on when the analyzer is turned on – proceed
immediately to section 6 Maintenance Battery.
The analyzer is supplied with an adapter for recharging the batteries or operating the analyzer continuously. Charging the
battery requires a common 9VDC adapter (positive pole located inside the female connector) supplied with the analyzer and a
convenience outlet. The analyzer’s charging circuit accepts 9VDC from any standard AC 110V or 220V adapter. The electronic
design enables the analyzer to remain fully operable during the 8-10 hour charging cycle.
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:
