4.4 Maintenance
Sensitron racommends an annual check of permance through a test gas with the proper
calibration kit.
If required, during these tests perform the Zero and Span calibration. Moreover, Sensitron
recommends to perform the same tests when the detector reports a gas reading above an
alarm threshold.
Test results should be recorded into a suitable book to be shown to the Authority in case of
inspection.
For further information, refer to the kit calibration manual MT894.

4. Testing, use and maintenance
4.1 Power ON
When the detector is powered on, the LEDs start blinking yellow during warmup time. After
one minute, the LEDs remain green during normal status.
Once the warm-up phase is over, the detector can work correctly, although the optimal per-
formances will be achieved after two hours.
4.2 Testing
Detectors are factory calibrated for the specific gas required by the customers. Future ad-
justment of the preset calibration can be carried out by employing the calibration keypad.
Testing should be carried out by using a gas mixture in the appropriate range, along with
our calibration kit.
4.3 Use
The detector works autonomously and automatically. Once adequately connected, no fur-
ther operations are required.
The frontal LEDs indicate the detector’s working condition.
