CALIBRATION
Calibration is the process of setting the readings of the instrument to
equal the value of certified calibration gases. Prior to calibration allow
the instrument to operate for 5 to 10 minutes in a room environment free
of combustible, CO, H2S or HCN gases.
Manually zero the instrument prior to beginning the calibration process.
NOTE:
Using calibration kits other than recommended by SENSIT
TECHNOLOGIES may cause inaccurate readings. Repairs are required
if any sensor fails to calibrate. Consult the factory for details.
NOTE:
When calibrating, the numbers shown on the display represent
the numbers seen by the microprocessor and should not be confused
with actual gas readings.
These readings will update every 5 seconds during calibration.
Definitions
AUTO CAL
is an automatic calibration process not requiring a docking station.
2.5% V/V
is the calibration point for the low end of the 100% volume sensor.
50% LEL
indicates calibration of the LEL and PPM sensors.
100 PPM CO
indicates the calibration point of the carbon monoxide sensor.
25 PPM H2S
indicates the calibration point of the hydrogen sulfide sensor.
10 PPM HCN
indicates the calibration point of the hydrogen cyanide sensor.
