The 9911B series of calibration box is used to verify and proof any High Voltage Insulation Testers. It can be utilized to calibrate all High Voltage Insulation Testers very accurately Analogs or Digitals.

Designed using the high quality switch combined with specially selected resistors,

this range of high ohm resistance is ideal for the calibration of insulation test sets having a voltage rating up to 10kV.

Housed in a rugged carrying case
