Gas Pup

22 Instruction 55-9002

Calibration

It is recommended that the Gas Pup be calibrated by your nearest

Bacharach Service Center. Calibration, however, can be performed in the

field if your facility has the necessary equipment and qualified personnel

to perform the procedures described in the following sections.

Gas Calibration Equipment Setup

The following equipment is recommended to calibrate the Gas Pup (refer

to the Accessories Section for part numbers):

• Calibration Kit (includes gas regulator, tubing, and instrument fitting)

• Calibration Gas:

- Zero Air (20.9% Oxygen, balance Nitrogen) (optional)

- 2.5 ±0.05% methane

- 100 ±2% methane

WARNING: If you are not using Bacharach’s calibration kit, be

sure not to apply pressure to the gas inlet from your own

calibration equipment. Use the excess flow calibration method,

otherwise incorrect gas readings may occur.

Connect the components of the calibration kit, calibration gas cylinder,

and Gas Pup together as shown in Figure 18. DO NOT connect the Gas

Inlet Fitting to the Pup until instructed to do so in the calibration procedure.
