1000:1 Voltage Divider Readout - Multi-meter Range Extender

The CAL5000 also includes an internal 1000:1 Voltage Divider. This divider gives the CAL5000 the ability to be used with a standard digital multi-meter as a  voltage display. In order to verify calibration  of higher voltage test equipment with a standard multi-meter, this calibrated read out circuit is necessary.

Intended Use
  • ​Periodic verification of electric motor test equipment indicated values. Including, but not limited to the following types of equipment:
  • ​Insulation testers
  • Meg-Ohm MetersContinuity Testers
  • AC/DC High Potential Testers
  • Surge Testers that have Meg-Ohm or  HiPot function
  • Digital Multimeters & DLRO’s
  • Other motor test equipment such as Motor Circuit Evaluations devices (MCE)


The CAL5000/CAL5000LT is a passive device designed to help maintenance professionals verify the calibration of their leading vendor’s electric motor test equipment. This device is of high value to companies that wish to self certify the performance of their electric motor test equipment. Technicians or engineers can quickly verify performance of their equipment versus this calibrated apparatus. It is intended to help avoid the shipment of expensive, sensitive test equipment, and is provided in a rugged transport shipment case, for its own periodic certification need.

​This self contained device carries an array of traceable and certified calibrated resistance values. The values contained in the device enclosure are selected based upon those generally required for verification of several leading manufacturer’s electric motor test equipment. The CAL5000 device carries an NIST traceable calibration certificate. A multi-vendor adapter test lead kit is furnished with the unit.

The CAL5000LT (Lite) is ideal for double checking results and to pre-test/verify field test equipment.
