Contact connection resistance testing device

This device is for measuring very small resistances of breakers, switches, springs and adjustable

The current is designed for 50-200 amps. The measurement method is the four-wire Kelvin method so that two props

The high ampere injects current into the resistor and the resistance voltage is measured by two voltage props and the unknown resistance value is calculated by the microprocessor controller.

It is noteworthy that the current applied to the resistor and the voltage from the resistor are measured by the controller

Autorunning and automation is done. Measured values include voltage, current and resistance calculated on

Graphic LCD is displayed. Test values are stored in the device’s internal memory and by a communication cable

Standard RS232 can be transferred to PC.

Applications

To measure very small resistors (resistance of connection contacts)

To measure the contact resistance on the shafts and bus loads

To measure the resistance of the weld joint

Technical Specifications

Input voltage of 200-240 volts with a frequency of 50 Hz and a current of 10 amps

Adjustable output current of the device for testing 50 to 200 amps

Loadless voltage 10 volts
