Using the Multi-PID 2
The following values are displayed: benzene concentration in ppm,
STEL value, the highest benzene measurement value recorded so far
(SMAX), the amount of measurements already carried out (SAMP) –
corresponds with the amount of PID pre-filter tube benzene already
used, and the sampling interval period of 90 seconds (SECS).
Pressing the "
view " key shows the Datalogger measurement values.
Pressing the " menu " key takes you back to the selection menu.
Pressing the " sample " key starts the measurement: the pump is acti-
vated and the measured air is drawn through the PID pre-filter tube
benzene for 90 seconds. The measurement status is indicated by the
flashing concentration value and by the flashing word
" sampling " .
The number 90 displayed under SECS counts down to 0. So the dis-
played number shows the remaining measuring time.
" SAMPLE
DONE " signalled in the display indicates that the measurement is fin-
ished.
The PID pre-filter tube benzene is a one-shot-device and cannot be
used for a second measurement. Repeatedly pressing the
" sample "
key will call up the information that the PID pre-filter tube benzene in
use is no good and that a new PID pre-filter tube benzene must be put
into the pre-filter tube holder. Only after inserting a new tube will
pressing the
" sample " key start a new measurement.
TVOC mode:
The Multi-PID 2 can power up in Logging Off, Tag, or Interval mode
depending on the mode that was set by the previous user. The current
mode is shown in the upper right-hand corner of the display.
