Note:

The unit may be zeroed without spanning it; however, never span the unit without first zeroing it.

The following procedure will calibrate the SMART-CELL.

To Enter ZERO / SPAN Mode

1.Push power button to turn unit on. Wait for power up sequence to finish (30 seconds).

2.Push and hold the unnamed button (second from left) first, then Push and hold the Menu button. Hold both buttons until the screen goes blank (2 seconds). Release both buttons and the unit is now in Programming Mode.

3.Push the SENS button and the unit is now in the zero/span mode.

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.

3.4Troubleshooting

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 Honeywell 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.
