Description

WMir

The current phototransistor signal from the water side of the mirror (the

unit of light reflected from the mirror surface).
During the analyzer’s first Purge cycle (Purging/Hold Stage) after a power-

up, this value will be at its baseline level because there are no liquids on

the mirror.

HCMir

The current phototransistor signal from the hydrocarbon side of the mirror

(the unit of light reflected from the mirror surface).
During the analyzer’s first Purge cycle (Purging/Hold Stage) after a power-

up, this value will be at its baseline level because there are no liquids on

the mirror.

The factory-set default configuration settings for your analyzer can be
found in the Documentation Package shipped with the analyzer.
