TI must be calibrated in horizontal position.
1
Connect TI positive lead to TI +50 A/250 mV input. After 250 mV check, move TI positive lead to TI + input.

3 Replace calibrator with power supply. Move positive lead to TI D.C. 5000 V input. Calibrate at 900 V if power supply not
available. After 5000 V check is complete, reduce output to minimum, replace power supply with calibrator and move positive
lead to TI + input.
