The gas analyzer should be checked periodically for accuracy, for normal shops unsing
the analyzer this would be approx. 6-9 months. For higher useage approx. every 3 months..
The analyzer can be calibrated in the field. In order to perform the calibration procedure you
will need a bottle of calibration gas and a calibration kit assembly (Figure 18). The calibration
assembly can be purchased from EMS or your local distributor. The recommended calibration
gas is Bar 97 Low and can be purchased from EMS, Part No.EMS-5502, BAR 97 LOW
Calibration

Calibration Procedure:
1. To begin the calibration procedure depress the “Menu” button on the sampling
screen. The main menu screen will show you the “CAL” button (Figure 19).Press the
“CAL” button and the display will show the stored calibration gas values (Figure 20),
compare these numbers to the calibration gas bottle. If the numbers do not match,
change the values using the “L” and “INC” buttons. The “_” indicates which # will
change, the “L” button move the _ left to the next digit, the “INC” changes the value.
This process is continued until all the calibration gas values are correct. At this point
press the “CAL” button.
