HL100 Contact Resistance Tester With Printer

As distribution networks carry heavier loads, overheating risk increases; regular contact resistance checks help detect faults early. This contact resistance tester measures contact resistances in circuit breakers, disconnecting switches, earthing switches, bus joints, bushing contact joints, and welding joints, as well as other low-resistance measurement applications. It provides 100 A DC test current, measures the test object voltage, and calculates resistance by Ohm’s law (R = U / I).

INSTRUCTION:

Overheating risk is becoming increasingly serious because today’s distribution networks must carry heavier loads. Periodic checks of contact resistance help identify faults before they lead to overheating. The contact resistance tester is used to measure contact resistances of circuit breakers, isolating (disconnecting) switches, earthing (grounding) switches, busbar joints, bushing contact joints, and welding joints. It is also suitable for low-resistance measurement applications. The tester supplies 100 A DC current. The voltage measurement is taken from the test object. The resistance is calculated using Ohm’s law: (R = U / I).

FEATURES:

Set the output current duration from 1 s to 60 s.
Save the instrument’s serial number for convenient result verification.
During testing, display the output current, output time, and resistance.
Store up to 100 test results in the tester’s memory.
Built-in clock records the date.
Stored results include the device number, testing time, and resistance.
The tester is equipped with a micro-printer.
