Hand cranked insulation resistance tester

The hand-operated insulation resistance tester can isolate and repair faulty components by testing the insulation resistance of different components in the system (transformers, switchgear, wires, motors). The use of insulation testing to verify the insulation between the test sample and the ground or between adjacent conductors is of great significance for ensuring product quality and personal and equipment safety during operation.

1Hand cranked insulation resistance testerProduct Introduction

By testing the insulation resistance of different components in the system (transformers, switchgear, wires, motors), faulty components can be isolated and repaired.

The use of insulation testing to verify the insulation between the test sample and the ground or between adjacent conductors is of great significance for ensuring product quality and personal and equipment safety during operation.

Before powering up the system, use insulation testing to verify its soundness and improve its performance; Insulation testing can detect manufacturing process issues and equipment defects, which are generally not detected before equipment failure occurs. In the European Union, this test is mandatory, even for the smallest civilian systems.

IIHand cranked insulation resistance testerFeatures

Multiple testing voltages, measuring insulation resistance up to 2T Ω.

The insulation resistance value is displayed digitally on a 31/2LCD.

Automatic range conversion for insulation resistance measurement, easy to read.

Measure the ambient temperature.

Automatic timing function, the instrument buzzer beeps briefly every 15 seconds.

Automatically measure, calculate, and store R15S, R60S, R600S, absorption ratio, and polarization index values.

The output short-circuit current is greater than 5mA, meeting the requirements for fast charging of capacitive loads.

Strong anti-interference ability, stable and reliable readings.

Complete protection functions ensure operational safety.

Rechargeable lithium battery power supply, automatically shuts down when the battery is low.
