4 APPENDIX 1 : HOW TO HANDLE INPUT
TERMINALS FOR CALIBRATION
4.1 Calibration of one
voltage
input
Voltage
input
with
interruptible terminals
(RTK/S, MTK P/P,...)
Voltage
input
without
interruptible
terminals
(SSK110, UK4,...)
Offset calibration
1. Open switches of both terminals (n,
n+10)
2. Short cut voltage inputs, BEN side
3. Start offset calibration process, wait
end of process
4. Remove short-circuit
Offset calibration
1. Disconnect USER wires from both
terminals
2. Short cut voltage inputs
3. Start offset calibration process, wait
end of process
4. Remove short-circuit
Gain calibration
5. Apply reference voltage source, BEN
side
6. Start gain calibration process, wait end
of process
7. Remove reference voltage source
8. Close switches of both terminals
Gain calibration
5. Apply reference voltage source
6. Start gain calibration process, wait end
of process
7. Remove reference voltage source
8. Connect USER wires again to both
terminals
