5.1.3 IR Emitter
The IR Emitter screen provides readouts of the detector’s voltage, current, resistance, and power consumption.
When contacting the Bacharach Service Department, the operator may be asked to provide this information to
help in the troubleshooting process.
To display the IR Emitter screen, first display the Diagnostics menu as described in Section 5.1. Next, use the
Up
and
Down
buttons to highlight “IR EMITTER” and then press
ENT
.
5.1.4 Pressure
The Pressure screen provides readouts of bench pressure, ambient pressure, the difference between the two
(delta), flow rate through the bench in moles per minute, and the tank pressure of the internal leak source.
When contacting the Bacharach Service Department, the operator may be asked to provide this information to
help in the troubleshooting process.
To display the Pressure screen, first display the Diagnostics menu as described in Section 5.1. Next, use the

the
Up
and
Down
buttons to highlight “CLR LAST FAULT”; press
ENT
; and then confirm this action by pressing
the
Up
button.
