Huazheng Electric HZ3151 5kV Insulation Resistance Meter

Features

The fully isolated power supply scheme is adopted, and the low-voltage circuit (battery-powered, human-computer interaction operation circuit) is completely electrically isolated from the high-voltage circuit (NC high-voltage power supply, signal sampling circuit); the isolation voltage is as high as 30kV, thereby ensuring the safety of operators.

It adopts an industrial-grade 7-inch color LCD screen with a high resolution of 1024×600, a viewing angle of 85°, and a brightness of 400cd/m ² ; it adopts a capacitive touch screen of explosion-proof glass, which has a good operating feel and a durable display.

It has a single-button shuttle function + buttons with color backlight, giving operators a better operating experience.

With 6 voltage ranges:

100V, 250V, 500V, 1000V, 2500V, 5000V.

Custom voltage mode 50V ~ 5000V continuously adjustable, step voltage 10V.

The maximum output short-circuit current is 6mA; and 1mA, 2mA, 3mA, 4mA, 5mA, 6mA are adjustable.

The maximum continuous output power is 25W.

With an independent discharge circuit, it can quickly discharge the test product after the test is completed.

It has the test functions of insulation resistance IR, absorption ratio DAR, polarization index PI, dielectric discharge rate DD and step voltage SV.

Support R600s/R30s and R600s/R15s two DAR absorption ratio calculation modes.

It has the functions of DC and AC voltmeters, can automatically identify DC voltage and AC voltage signals, and can measure the frequency of AC voltage signals.

 It has the function of measuring cable length.

With controllable hardware filter and software filter, the anti-interference performance of the instrument is greatly improved.

The test time in various test modes is saved independently and does not affect each other, which is convenient for the next use.

It has the functions of automatic shutdown of the instrument when it is idle and automatic shutdown when the battery is low, and the automatic shutdown time can be set.

With USB storage function, test data can be exported to USB in batches; and it supports the function of upgrading the main control firmware and high-voltage power supply firmware through USB.

It has RS232 (optional RS485) communication interface.

With Bluetooth communication function.

Built-in large-capacity lithium battery and built-in fast charger; both the instrument panel and LCD screen can indicate the current charging status.
