Zero Calibration

4) Be sure the unit is in clean air or apply zero air for two minutes.

5) Push ZERO button.

6)Push SAVE button to save the new zero calibration.

Span Calibration

7)Push SPAN button.

8)Apply span gas for two minutes.

9)Push INC button (increase) or DEC button (decrease) until the display matches the span gas concentration.

10)Push SAVE button to store new span calibration.

To Exit ZERO / SPAN Mode

11)Push DONE button twice slowly to get back into normal operation mode.

DTroubleshooting

Unit does not respond when keys are pressed:

Press and hold all four buttons for five seconds. This will reset the Manning 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 11. Verify that alarm is not programmed as a downscale alarm, and that the setpoint is above zero.

The detector does not start: Check to see that a fresh battery is installed. Both the primary and standby batteries must be discharged for this problem to occur. Plug the charger into the Manning EC-P2 to charge the standby battery. Wait 10 minutes and retry.

The detector does not respond to the target gas:

Verify the proper flow rate using the supplied flowmeter. Perform calibration. If sensor won’t calibrate, the SMART-CELL may be depleted. Contact Honeywell Analytics for a replacement

SMART-CELL.

Pump alarm: This will occur if the pump motor stops or if an internal pressure sensor detects blockage of the inlet. Check that the internal filter is not clogged or wet and that the inlet tube is clear.

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