How To Configure the Sensor Parameters
The 651 controller is initially configured to use 100 Torr as the sensor full scale range, and
0 to 10 Volts for the sensor input signal. Follow the steps below to change these parameters.
Note
Be sure that the sensor is connected to the 651 controller before changing
the sensor parameters.
How To Change the Sensor Type
The 651 controller can work with either Absolute or Differential pressure sensors. Issue the
following command to select the sensor type:
U
value
where
value
is 0 for Absolute; 1 for Differential.
How To Change the Sensor Full Scale Voltage
The 651 controller is initially configured for a 10 Volt full scale sensor. To change the full scale
voltage, issue the command:
G
value
ENTER
where
value
is a valid sensor full scale voltage. Valid full scale voltages are:

0 = 1 Volt
1 = 5 Volts
