If you suspect the internal filter is blocked perform the following:

• Remove the probe connection from the water trap.
• Empty and clean the water trap with a dry cloth.
• Fit a new external particle filter.
• Run the instrument in fresh air (pump ON) for at least one hour.

If the problem does not clear contact a service agent.

10. ZERO CHECKS AND RE-CALIBRATION

During normal operation of the analyzer the following checks may be requested as required:

• Zero setting of all sensors (can also be selected manually)
• HC residue check (automatic) Certain analyzers only.
• Leak test
• Calibration check.
• Re-calibration.

10.1 Zero Setting

The zero setting function sets the working sensors to zero using fresh air. This function is activated as follows:

• Following analyzer switch ON.
• On a timed basis. Following the analyzer first being turned ON a zero will requested 

automatically at 7, 15 and then 30 minute intervals. Subsequent requests will be 
every 30 minutes.

• On request by the user from the SELECT MENU

The zero sequence is as follows, ensure the on screen commands are followed or the analyzer may not 
zero correctly.

Ensure the probe is removed from the vehicle exhaust and is sampling fresh air, in the garage environment
this should be 45 meters or 18 inches above the ground. Once this is done press 

to activate the pump.

WARNING!

The sensors will only be reset if the probe is sampling fresh air for at least 60 seconds.

Once the zero is complete the screen will return to the MAIN DISPLAY.

If the analyzer fails to zero it may request a HC residue check. (Certain analyzers only)
