5. Operation
5.2.3 Calibration procedure using a multi-meter (cont’d)
3 - Check if the indication of the multi-meter returns to zero concentration (4 mA)
after removing the calibration gas.
4 - If necessary repeat steps 2 until 4.
5.3 Span response test
If desired, an extra span response test may be carried out between the normal maintenance
intervals.
The test can be performed with a standard gas or with one of the gases, which can be
generated by using a Bionics Instrument calibration kit (for information see: appendix 2)
Steps to follow:
- Put the connected alarm/control unit in “stand-by” mode.
- Expose the system to calibration gas (see sect. 5.2.2 / 5.2.3)
- Check the signal, depending on the configuration, using either the local indicator or a multi-
meter.
If the application requires an adjustment of the signal please perform a full calibration as
described in previous sections.
Calibration gases can be harmful.
Ensure that during calibration these gases are vented to
