Ambient Temperature Calibration; Co Sensor Zero & Calibration - Bacharach Monoxor III Operating & Maintenance Instructions

5.2 Ambient Temperature Calibration

Material Required:
Procedure:
1. Enter the Calibrate Mode as described in Section 5.1. Observe that
"AMBIENT" is displayed at the top of the display; if not, repeatedly
press ENTER until it appears.
2. Use the ▲ and ▼ buttons to adjust the displayed value to match
the reading of a calibrated thermometer.

5.3 CO Sensor Zero & Calibration
Material Required:
If you are primarily performing flue-gas testing, calibrate the Monoxor III
with 500 ppm CO calibration gas. If the analyzer will be primarily used for
ambient testing, then you may wish to consider 100 ppm CO calibration gas.
Procedure:
1. With the analyzer sampling fresh air, enter the Calibration Mode as
described in Section 5.1. Then repeatedly press the ENTER button
until "CO" appears in the upper left side of the display.
