Using the Multi-PID 2
Beginning Operation
Turning the Multi-PID 2 On
1. Turn the Multi-PID 2 on by pressing the -key.
2. The Multi-PID 2 will display the instrument’s software version num-
ber. Next the Multi-PID 2 will proceed to the mode display.
3. The Multi-PID 2 has an instant-on lamp. For maximum accuracy
and stability, allow the Multi-PID 2 to warm-up for 10 minutes prior
to calibration.
Default Display
The display shows the last mode the Multi-PID 2 used. The resolution
of the display changes with the magnitude of the reading. A reading
of 0 to 99.9 will be displayed with a resolution of 0.1 ppm. A reading
greater than 99.9 will be shown with a resolution of 1 ppm. The meter
will display concentrations up to 2,000 ppm.
GAS mode:
In GAS mode, the PID pre-filter tube benzene (Order No. 81 03 511)
can be used to measure benzene, or a sample collection tube (Order
No. 67 33 011) can be filled with a defined amount of a sample.
The GAS mode is a filter tube mode. This means that all measure-
ments require the installation of the pre-filter tube holder (83 10 093)
and of the pre-filter tubes. The PID pre-filter tube benzene which is
mounted at the head end of the tube holder and adsorbs all sub-
stances with the exception of benzene is used to selectively measure
benzene. The entire process is menu-driven. The selective benzene
measurement value is displayed after 90 seconds.
Activating the GAS mode opens a dialog which queries a device cali-
bration. The benzene measurement screen is displayed after installa-
tion of the PID pre-filter tube benzene.:
