Introduction
Support Equipment and Consumables
Calibration
For normal operation these items are required:
1. Calibration Gas Regulator (Part No. 68 10 688).
2. Calibration gas containing 100 ppm isobutylene (Part No.
68 10 687). Other concentrations of the calibration gas may be re-
quired. This will depend on your application.
3. Zero air (clean dry air without any organic impurities)
There are several alternatives for clean or zero air calibration: you
can use a bottle of clean air (certified as having not more than
0.1 ppm total hydrocarbons) connected directly to the instrument;
the clean air can be transferred to a Tedlar bag which can then be
connected to the instrument; clean, ambient air without detectable
contamination; or, ambient air run first through the charcoal filter
(Part No. CH 24 101).
4. If compound threshold limit values (TLVs) are exceeded, you
should use a gas bag for sampling and calibration.
To determine the TLV of the compounds contained in the calibra-
tion gas, refer to the Material Safety Data Sheet (MSDS) supplied
with your calibration gas cylinder.
Field Operation
For field operation, the Multi-PID 2 Field Kit (Part No. 83 17 663) is
available.
The field kit includes a cable kit, a carrying case and a calibration
regulator, and a spare battery pack.
Refer to the check list in on page 41 to ensure you have all the neces-
sary accessories and equipment before beginning field operation.
Computer
The Multi-PID 2 may also be connected to a computer. The computer
must be a Windows
TM
-based PC.
Use the cable kit (Part No. 83 17 667) to connect the Multi-PID 2 to
the computer.
Stored datas are evaluated using the Dräger GasVision software
(Part No. 83 14 034).
WARNING:
The Multi-PID 2 is not classified for use in hazar-
dous locations when connected to a computer,
danger of an explosion!.
