4.2. CO SENSOR CALIBRATION (ONLY HD37AB17D)
It’s possible to calibrate the CO sensor zero in clean air (in an external environment
the CO concentration is less than 0,1ppm) or using nitrogen cylinders (code MINI-
CAN.12A).
CO zero calibration in clean air:
1.
Put the instrument in an environment with clean air (the concentration of CO in
the external environment is less than 0.1ppm), switch the instrument on and
wait at least 15 minutes because the measurement must stabilize.
2.
Connect the instrument to the PC by USB connection cable code CP22 and start
DeltaLog13 program, so follow the instruction connected with the
CO zero
cali-
bration.
CO zero calibration with nitrogen cylinder (code MINICAN.12A):
1.
Using a screwdriver, open the wicket on the frontal side of the instrument.
2.
Connect the pipe coming from the MINICAN.12A cylinder with the rubber cowl-
ing on the CO sensor head.
3.
Connect the instrument to the PC by the USB connection cable code CP22 to
the PC and start the DeltaLog13 guided process of sensors calibration.
