Calibrate the SGM device using ProLink III

SGM calibration is required to generate calibration coefficients for your process gas. These
coefficients are required for accurate measurement.

b. Activate SCROLL to view the calibration factors and data.
Results are displayed in this order:
• The specific gravity, molecular weight, or relative density used to calculate
the K0 calibration factor
• The time period used to calculate the K0 calibration factor
• The specific gravity, molecular weight, or relative density used to calculate
the K1 calibration factor (3-point calibrations only)
• The time period used to calculate the K1 calibration factor (3-point
calibrations only)
• The specific gravity, molecular weight, or relative density used to calculate
the K2 calibration factor
• The time period used to calculate the K2 calibration factor
• The K0 calibration factor
• The K1 calibration factor (3-point calibrations only), displayed in exponential
format
• The K2 calibration factor, displayed in exponential format
c. When Exit appears, activate Select.
Select the calibration to be used for measurement.
a. Activate SCROLL until CAL ACTIVE appears.
b. Activate Select, then scroll through the list of options.
c. When the desired option appears, activate Select, then store the selection.
(Optional) To add a calibration, return to the first step and repeat this procedure.

Troubleshooting SGM calibration
You must have completed the purge procedure, and the reference chamber must
be filled with the reference gas to the appropriate control pressure.
You must know whether you want the device to operate as a specific gravity meter,
a molecular weight meter, or a relative density meter.
You must know whether you want to perform a two-point calibration or a three-
point calibration.
You must have identified all required calibration gases and know their specific
gravity, molecular weight, or relative density.
