Pumped Models (PGM-25XX)
The PGM-25XX’s internal pump has two speed settings: low or high. The pump draws at
a flow rate of between 200cc/min and 450cc/min. The instrument must be connected to a
cylinder of calibration gas with supplied tubing featuring a T calibration tube, as
illustrated below.
Note:
A constant-flow regulator with flow rates from 500cc/min to 1000cc/min should be
used.
Diffusion Models (PGM-25XXD)
RAE Systems’ provided calibration cap should be installed on the diffusion versions of
the instrument when it is being bump tested or calibrated. A constant-flow regulator with
flow rates from 500cc/min to 1000cc/min should be used.
WARNING:
Make sure the calibration cap clips on and stays in t correct position during
calibration, as illustrated below.
