Setting the Sensor Signal Input Range
Note
Be sure that the sensor is connected to the device before changing the sensor signal input
range.
The [
G value
] command sets the full scale voltage range for the pressure sensor input, where:
value:
0 = 1 Volt
1 = 5 Volts
2 = 10 Volts (initial)
To query the current range of the sensor signal input, issue the request:
R 35
The controller responds with the message [
G
value
], where:
value
: 0 = 1 Volt
1 = 5 Volts
2 = 10 Volts
If the sensor input has a full scale range of 10 Volts, an example response is:
G
2
To change the sensor signal input range to 5 Volts, enter:
G 1
Setting the Sensor Range
Note
Be sure that the sensor is connected to the device before changing the sensor range.
The [
Ex value
] command identifies the range of the sensor, in units, where
x
corresponds to either ‘H’ or ‘L’
for the High or Low pressure sensor, and
value
corresponds to a valid sensor range, as listed in Table 7.
The device is initially configured to work with a 10 and a 1000 Torr pressure sensor. If your sensors cover
different pressure ranges, use this command to identify the range of your sensor.
