BW Clip4 Calibration Procedure

Calibration

The calibration symbol and cylinder symbol appear with the flashing non-compliance symbol when calibration is overdue.

Make sure that the ambient air is clean and free of hazardous gases before starting this calibration procedure.

NOTE

Honeywell Analytics provides a quad gas mixture for accurate bump tests and calibrations. Use the quad gas mixture rather than a single gas.

1. Press the button twice in succession to get into the menu, skip ahead to by repeatedly by repeatedly pressing the button, and then press and hold the button to initiate a calibration.

2.. appears with the flashing zeroing symbol . Wait until this zeroing process is completed

3.When the zeroing process is successfully completed,, appears. If it fails ,appears with the flashing non-compliance symbol .

4.Connect a cylinder of calibration gas to the gas detector using the calibration cap. For details about how to use the calibration cap, see Calibration Cap

5.Whenappears with a 60-second countdown, apply the calibration gas to the detector at a flow rate of 250 to 500 ml/min before the countdown is completed.

To cancel this calibration, briefly press the button.

6.When appears, close the cylinder valve.

7.When the calibration is successfully completed,, appears. If it fails ,appears with the flashing non-compliance symbol .

8. appears with the number of remaining days until the next calibration.

9.Remove the calibration cap from the detector.

If repeated attempts continue to fail, contact Honeywell Analytics or your distributor for technical assistance

Calibration Cap

The calibration cap, which is provided as part of the package, is required to do a bump test or calibration. Use this method to apply calibration gas to the gas detector.

1. Connect a tube from a cylinder of calibration gas to the calibration cap's right spigot.

2. To attach the calibration cap to the gas detector, hook the cap's left clip to the corresponding groove of the detector and snap the right clip into place.

3. When appears on the display of the detector, open the cylinder valve by turning the pressure regulator knob counterclockwise.

When appears, close the cylinder valve by turning the pressure regulator knob clockwise.

CAUTION

Make sure that the gas cylinder meets either of these pressure requirements:

Disposable cylinder: 0 to 1000 psig/70 bar
Refillable cylinder: 0 to 3000 psig/207 bar

Do not use an expired gas cylinder.
