Insulation resistance tester should pay attention to what features

In the use of insulation resistance tester should pay attention to what features:

1, the resistance range can be automatically converted, and there are corresponding instructions.

2. Both ways display the insulation resistance synchronously. The mechanical pointer adopts ultra-thin flat wire structure for strong earthquake resistance. The adoption of the mechanical pointer makes it easy to observe the variation range of the insulation resistance. The adoption of the dot matrix LCD screen can guide the user to operate the instrument and can accurately obtain the measurement results.

3, mechanical head and LCD screen into one. Double scale display, automatic range conversion. The color scale is easy to read.

4, using embedded industrial microcontroller and real-time operating software system. With high degree of automation and strong anti-interference ability, the instrument can automatically calculate the absorption ratio and polarization index without manual intervention.

5, friendly operation interface, a variety of measurement results with anti-power-down function, can store 20 consecutive measurement results.

6, when the instrument produces high pressure, there is a sound output.

7, built-in residual high-pressure discharge circuit, after the test can automatically let go of the residual pressure on the device under test.

8, AC and DC, configuration rechargeable battery and AC adapter.

9, the instrument uses a portable design, easy to field operations.

Insulation resistance tester current leakage will produce the following problems:

1. When the current passes through the insulating layer, heat is generated, which deteriorates the insulating layer until the final insulation fails, and a fire hazard may occur.

2. Leakage current must be returned to the source and it will return to the source through any available conductor, line, pipe, water, or ground. This unfavorable current can generate dangerous voltages.

3, leakage current is inefficient. Currents leaking through the insulation do not drive the motor, light or heat, but they still consume.

4. Insulation resistance tester leakage current will cause the overcurrent protection device to trip, causing the motor and transformer to overheat. The result is poor electrical insulation that causes equipment failure and shutdown of the production line. No factory can withstand unplanned downtime now. "Customers need to diagnose faults quickly. No one wants to lose production time, and many customers are eager to know if they need to repair equipment or simply replace it."
