Remove both fuses and insert two new fuses. These must be
identical and should correspond to the line voltage.
• ITC-155: 115V, 2AT = 105014 / 230V, 1AT = 105007
• ITC-320/650: 115V, 10AF = 60B302 / 230V, 5AF = 60B301
If the fuses blow immediately after you have replaced them,
the calibrator should be returned to the manufacturer for
service.
Slide the fuse box into place with the correct voltage turning
upwards.
