External flowmeter indicates no flow: Verify that pump is running. Check that the manifold screws are tight and the extension wand connection is tight.

Unit does not respond when keys are pressed: Press and hold all four buttons for five seconds. This will reset the Honeywell EC-P2. Turn the unit back on by pressing the PWR button.

High reading won’t clear: When the sensor is exposed to very high gas concentrations, it takes a relatively long time for the sensor to clear. Leave the unit running in a clean environment for a few hours to clear the sensor. If it doesn’t clear after six hours, the sensor may have been damaged. Contact Honeywell Analytics for a replacement SMART-CELL.

Unit is in alarm with gas reading of 0 ppm: Check the alarm setpoints and alarm functions as described on page 12. Verify that alarm is not programmed as a downscale alarm, and that the setpoint is above zero.
