KD5000 Line Insulation Resistance Tester

KD5000 Line Insulation Resistance Testercharacteristic

1. Large screen display, with output voltages of 0.5kV, 1kV, 2.5kV, 5kV, and 10kV that can be set. The instrument will not be burned out in short-circuit state, and the short-circuit current is ≥ 10mA. The actual output test voltage and real-time leakage current are displayed on the same screen in real-time.

2. The analog pointer and digital display are displayed on the same screen. The numbers reflect the accuracy of the insulation resistance of the test sample, and the analog pointer can reflect the dynamic changes in insulation resistance during the testing process.

3. It has functions such as actual sample voltage measurement, leakage current measurement, and automatic discharge. Through the actual sample voltage measurement function, it can intuitively display whether the drop voltage of the test instrument with load meets the standard requirements.

4. It can automatically measure and memorize R15S, R60S, and R10min values, and automatically display the polarization index (PI), absorption ratio (DAR) test values, and test time.

5. Automatic discharge: Advanced high-voltage discharge technology is used to quickly discharge capacitive test samples, and the discharge voltage is measured in real time during discharge (the test voltage of the sample is up to 0V). For large capacitive test samples, manual discharge is required to ensure personnel safety due to the absorption of charges by the medium.

6. Intelligent battery charging management can effectively prevent battery overcharging from shortening or damaging battery life, with digital display of battery level and protection against undervoltage alarm. It can be powered by internal rechargeable lithium batteries or external AC power supply, and can truly be used for both AC and DC without affecting testing accuracy.

7. Alarm function during boost, the buzzer has a warning function when the device has high voltage output, indicating that there is high voltage output at this time.

8. Automatic shutdown function: This instrument has an automatic shutdown function, which will automatically shut down 5 minutes after the measurement is completed.
