2 of CHA value and port 2 of CHB value connect to anther two
ends of Tee-union, port 3 of CHA value connects to CHA Gas, port
3 of CHB value connects to CHB Gas.
4. Connect the vacuum pump power cord to the white circular
grounded power supply, labeled PUMP, on the rear panel of the
instrument. Clockwise rotate the connector of pump to make sure
firmly.
5. 3-way values for two channels need to fix on the rear panel firmly.
Connect cables of two 3-way values to sockets rear panel that
marked as CHA and CHB.
6. Connect the 4-pin Temperature/RH cable to the 4-pin connector
labeled RH/TEMP on the rear of the monitor.
7. Be sure that the pressure sensor calibration port toggle switches on
the rear panel are pushed outward and away from the barbed +/-
Delta P.
8. Set monitor power switch to the ON position.
During startup, the iSeries splash screen will be shown followed by a
mechanical filter tape change and a cycling of the pump power.
To continue with the acceptance testing:
From the Main Menu select Diagnostics > RH/Temperatures.

The RH/Temperatures screen (read only) displays the current relative
humidity in percent and the temperature readings in °C. The board
temperature is the air temperature measured by a sensor located on the
measurement interface board.
Press to return to the Diagnostics menu, and choose Pressure/
l
Vacuum.
The Pressure/Vacuum screen (read only) displays the barometric,
vacuum, and flow pressure readings in mmHg. The pressure is measured
by a pressure transducer. The vacuum is the amount of vacuum under
