tinb07e1-e 2011-07 Vacuum Gauge Controller 47
The calibration offset of the respective channel is deter-
mined and stored in the EEPROM.
Calibration factor
5 Remove the D-Sub plug with the wire strap from
the sensor connection of the respective channel
6 Connect pin 2 (Signal) and pin 12 (Signal-GND) of
a 15-pin D-Sub plug with a high-precision voltage
source. See Chapter 3.3.4 SENSOR, 12.
• Pin 2 = +10.000 V
•Pin 12 = GND
7 Put the D-Sub plug with the voltage source con-
nections onto the sensor connection of the respec-
tive channel
8 Use the serial interface to send the command
CAF,a to the unit. For the parameter a, use:
• 0 = Channel 1
• 1 = Channel 2
• 2 = Channel 3
The calibration factor of the respective channel is deter-
mined and stored in the EEPROM. Now the channel is
calibrated.
