a range for POSITION: 0 = 0 – 1’000, 1 = 0 – 10’000, 2 = 0 – 100’000
bcdefgh upper value for PRESSURE and SENSOR READING: 1000 ... 1000000
e.g. 0010000 -> pressure range 0 – 10’000
This function defines the communication range between the valve and the host computer
for POSITION, PRESSURE and SENSOR READING.
Note: In case ZERO has been performed, gauge offset for PRESSURE and SENSOR
READING is compensated.
Note: In case 2 sensor operation for pressure control is selected, PRESSURE covers high
range gauge because switchover between sensors is done automatically.
SENSOR 1 READING and SENSOR 2 READING always return full scale values
according to selected range.
Above picture shows a 2 sensor system. In this configuration sensor 2 covers low range (100 mTorr) and sensor 1
covers high range (1 Torr). RANGE CONFIGURATION for PRESSURE resp. SENSOR READING is set to 10’000.
Switchover between sensors is done automatically.
