Using the Multi-PID 2
Operational Check List
Before beginning field work, set up and calibrate the Multi-PID 2 for
your particular application.
To ensure the instrument is in working order before heading into the
field:
1. Ensure the battery pack is fully charged. If you are unsure about
the status of the battery, replace the battery pack with one that is
fully charged. See battery charging on page 26.
2. Perform a flow test:
Switch on the device (pump modus starts automatically).
Block the gas inlet after 60 sec (close the hose end or hold the in-
let closed). The operating noise of the pump changes audibly, it
may also stop completely.
a. Flowtest OK:
The device changes to alarm mode after a short time: "Pump
Error" is displayed on the display and a short alarm tone is
audible. Confirm the alarm by pressing the top middle key.
b. Flowtest error:
No alarm is triggered after blocking the gas inlet for 10 sec.
Switch off the device. Contact DrägerService.
3. After calibration is complete, sample the calibration gas and the
bag of zero air to ensure the Multi-PID 2 has been calibrated cor-
rectly.
4. Select the correct operating mode. See Section regarding Opera-
tion Modes page 54.
CAUTION:
A flow test to check the tightness of the system and the
function of the flow alarm has to be performed before
each measuring mode.
