Calibration

The supplied sample hose needs to be connected to accomplish proper Calibration.
Verify the Sampling Hose assembly is connected to the analyzer and making sure it is
disconnected from any refrigerant source before Calibration. When you first turn the
unit on an Air Calibration will be required; additional Air Calibrations are only required
periodically. A reminder to perform air calibrate will appear when needed (Figure 4). Press
'CAL' to calibrate the machine. When calibrating, the unit will pull fresh air into the sample
cell via an internal pump. This fresh air purges any excess refrigerant and ensures accurate
test results. Calibration requires that the sample hose is disconnected from the refrigerant
cylinder or air conditioning system and remains connected to the instrument. (Figure 5) will
display while the Air Calibration is occurring. Calibration will take approximately 130 seconds.

OFF
NOTE:
In the unlikely event an 'Air Calibration Unstable' message is displayed as shown in
(Figure 6) verify you are in a ventilate area and there is no gas flowing near the air intake.
Once you have verified both parameters, press 'RETRY' to complete another calibration.
