MODE SELECTOR switch and indicators
The three position switch selects the calibration mode. LEDs indicate the current
mode.
• ZERO: The permeation chamber output is dumped out the chamber vent;
only the dilution stream exits through the stream outlet to the analyzer.
• SPAN: The permeation chamber output and the dilution stream are mixed
and fed through the stream outlet to the analyzer.
• REMOTE: Unit defaults to the ZERO mode. A remote contact closure to rear
panel terminals C and V1 will switch the unit to the SPAN mode.
