Routine Maintenance
Calibrating the Multi-PID 2 with the Flow-Match Regulator
1. Ensure that the short sample probe is connected to the Multi-
PID 2 inlet. If you are using the long probe for sampling, then en-
sure the long probe is connected to the Multi-PID 2.
2. Press the -key for approx. 2 seconds.
3. Follow the instructions on the display and either connect the Multi-
PID 2 to zero air, connect the optional activated charcoal filter
(Part No. CH 24 101) and filter tube holder (Part No. 83 19 093),
or leave the instrument unconnected so it can sample clean ambi-
ent air. Then press the
“ next ” key. The Multi-PID 2 will take 60-90
seconds to set the zero point for calibration.
4. The Multi-PID 2 display will show » Zero air calibrated. Continue
calibration? « Press the “ next ” key.
5. Enter the span gas concentration if the concentration displayed on
the Multi-PID 2 is different than the concentration of the span gas
cylinder. Press the
" new " key and follow the display prompts. For
further information, see page 36 for numeric value, duration, time,
and date entry. If the span concentration matches the span gas cy-
linder concentration, press the
“ next ” key. To exit calibration,
press the “ cancel ” key.
6. Ensure the calibration gas cylinder is upright and open the regula-
tor by turning the valve counter clockwise. Open the regulator until
the ball is 1/8” from its rest position.
7. Connect the span gas to the Multi-PID 2 (if the zero air calibration
was done with either a Zero Air cylinder or the optional activated
charcoal tube and tube holder, either should be disconnected be-
fore connecting the span gas fitting to the Multi-PID 2).
8. The Multi-PID 2 will take 60-90 seconds to set the span set point.
When finished with the calibration, the Multi-PID 2 will display
» Calibration complete! « .
NOTE:
Ensure the sample probe is free of any contamination, as this
will affect the calibration.
NOTE:
If you are not using the Dräger Safety Flow-Match Regulator,
ensure that the inlet pressure is less than 0.35 bar (5 psi) when
calibrating.
NOTE:
While the Cal status is active, all alarms are deactivated.
