Calibrating the Solaris Multigas Detector

Each Solaris Multigas Detector is equipped with an Autocalibration
feature to make unit calibration as easy as possible.
The Autocalibration sequence resets instrument zeroes and adjusts
sensor calibration for known concentrations of calibration gases.
Table 4-1. Autocalibration and Required Calibration Cylinders
SENSORS EXPECTED GAS*
CONCENTRATION
Combustible 58% LEL
Combustible 2.5% CH 4
Oxygen 15%
Carbon Monoxide 60 ppm
Hydrogen Sulfide 20 ppm
Nitrogen Dioxide 10 ppm
*Factory Default
NOTES:
• Refer to Chapter 3, "Setting up the Multigas Detector", for instructions on changing the
autocalibration expected gas concentrations if calibration gas with concentrations other
than those listed above will be used to calibrate the instrument.
• For 30 C.F.R. Part 75 determinations (MSHA versions), the Solaris Multigas Detector
must be operated in the 0-5% by volume CH 4 mode and must be calibrated with 2.5%
by volume methane.
The expected gas concentrations must match the gas con-
centrations listed on the calibration cylinder(s). Failure to
follow this warning will cause an incorrect calibration, which
can result in serious personal injury or death.
