Sensor Replacement

1. Use the 3-pin end of the tool to unscrew and open the filter holder at the bottom of the monitor.

2. Use the hexagonal end of the tool to open the remove the sensor cover, turning

counterclockwise.

3. Pull the old sensor out.

4. Gently push a new sensor into the compartment.

5. Replace the sensor compartment cover using by turning it clockwise, using the hexagonal end

of the tool.

6. Replace the filter holder by turning it clockwise, using the 3-pin end of the tool.

WARNING:

Only replace the sensor in non-hazardous locations.

Always calibrate the instrument after changing a sensor. If the sensor fails, try to calibrate it again.

If calibration fails again, replace the sensor.
