TI must be calibrated in horizontal position.
1
Connect positive lead to TI +1V DC input. After 1V check is complete, reduce output to minimum and move positive lead to
2
TI + input.
3 Reduce output to minimum and move positive lead from TI + input to TI 1000V DC/AC input. After 1000V check is
complete, reduce output to minimum and move positive lead to TI + input.
