Function switch to DC VOLTS 1 KΩ.
1
Reduce output to minimum and move positive lead from TI V-Ω-A input to TI AC/DC 1000 Ω/V 1000 V input.
2
3 Reduce output to minimum. Replace calibrator with power supply and move positive lead to TI V-Ω-A input to TI AC/DC
1000 Ω/V 5000 V input. Calibrate at 700 V if power supply is not available.
4 Reduce output to minimum and set TI function switch to DC VOLTS 20 KΩ and move positive lead from TI V-Ω-A input to
TI AC/DC 20000 Ω/V 5000 V input. After 5000V check is complete, replace power supply with calibrator and move positive
lead to TI AC/DC 20000 Ω/V 1000 V input.
5 Reduce output to minimum and move positive lead from TI AC/DC 20000 Ω/V 1000 V input to TI V-Ω-A input.
