Calibration Gas

Do not use 100% nitrogen as a low gas (zero gas). It is suggested that gas for the low
(zero) be between 0.4% and 2.0% O
of more than 40 parts per million. Failure to use proper gases will result in erroneous
readings.
Two calibration gas concentrations are used with the Hazardous Area Oxymitter 4000,
Low Gas - 0.4% O
Oxymitter 4000 connections.
If using an IMPS 4000 or an SPS 4001B, install it in a non-hazardous, explosive-free
environment.

IMPS 4000 connections

Ensure the IMPS 4000 is installed in a safe (non-hazardous, explosive-free) area and verify
the wiring and pneumatic connections per the IMPS 4000 Intelligent Multi-probe Test
Gas Sequencer Instruction Manual.

SPS 4001B connections

Ensure the SPS 4001B is installed in a safe (non-hazardous, explosive-free) area and verify
the wiring and pneumatic connections per the SPS 4001B Single Probe Autocalibration
Sequencer Instruction Manual.
