If the N2 gas concentration exceeds the set low or high alarm points, the device will activate its audible, visual (light), and vibrating alarms to alert the user.

7. መለካት

Regular calibration is crucial for maintaining the accuracy and reliability of the gas detector. Calibration should be performed by qualified professionals using necessary accessories and standard gas. Typically, calibration should be done yearly.

ዜሮ መለካት;

Zero calibration is performed when the drifting is too large after the reading is stable, or if an alarm occurs unexpectedly. This ensures the device reads zero in a clean air environment.

Span Calibration (Target Point Calibration):

Span calibration involves applying a standard gas of a specific known concentration to the sensor without atmospheric dilution. The calibration result should match the concentration of the standard gas.
