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.
