adapter (Part No. MX395072 - gas bag, MX395073 -
gas bag and adapter).
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 calibration gas, refer to the Material Safety Data
Sheet (MSDS) supplied with your calibration gas
cylinder.
If you will be using a gas bag for calibration, you should
obtain the calibration kit (Part No. MX390033). The
calibration kit contains a regulator, a gas sampling bag
and a gas bag adapter. See Calibration Using a Gas Bag
on page 73 for details.
Field Operation
For field operation, a 2020 Field Kit (Part No. MX350005) is
available. The field kit includes a cable kit, a carrying case and a
calibration regulator, spare battery pack and a cylinder of 100 ppm
isobutylene calibration gas.
Refer to the check list in Preparing for Field Operation on page
82 to ensure you have all the necessary accessories and equipment
before beginning field operation.
Printer
2020 may be used with a printer to generate printed reports. The
printer must have a printing width of at least 65 characters and must
use fixed spaced fonts. See
Printer on page 89 for details of
connecting a printer to 2020.
If you are using a parallel printer, you will need the serial to parallel
converter (Part No. MX380145). See
Serial to Parallel Converter
on page 96 for details of connecting and operating 2020 with a serial
to parallel converter.
