●DM100CInsulation resistance testerIt is a compact, high-voltage output, battery powered testing instrument that can be used to measure insulation resistance test items such as absorption ratio and polarization index.

●DM100CInsulation resistance testerApplicable locations: DM100CInsulation resistance testerIt is designed and developed to solve the evaluation of electrical insulation quality of large high-voltage transformers, motors, generators, long-distance power cables, tubular busbars, etc. under strong interference in high-voltage substations and power plants. The instrument has a large output power, real-time voltage measurement (actual charged voltage of the test sample), leakage current measurement, and automatic discharge (discharge voltage measurement), which are particularly suitable for high-capacity test samplesTest site with strong interference above 110kV.

●Intelligent voice prompt function.

●Sound prompt after startupWelcome to use the insulation resistance tester. Please choose the appropriate voltage for measurement. After startup, the sound prompts "High voltage danger, do not approach". After the automatic measurement is completed, the sound prompts "Measurement completed, automatic discharge is in progress, and then the discharge is completed. It is safe to disconnect the wire with a discharge voltage of 0V".

Strong anti-interference ability, single machine can resist AC2000 AC interference without damaging the instrument.

2.Performance characteristics

● Design strictly in accordance with safety standardsOutput voltage: 500v 1000v, 2500v, 5000v, 10000v.

The anti-interference ability is AC3000V, and the induced current is 600mA, which can cope with extremely harsh testing environments.

5.7-inch large screen display, actual test voltage display, leakage current display.

● True automatic discharge function, no need for manual discharge.

● Short circuit current≥10mA。

● This instrument has an automatic calibration function, which automatically calibrates the accuracy before testing.

This instrument has the functions of measuring the actual live voltage of the test sample, measuring the leakage current, and automatic discharge. Through the actual live voltage measurement function of the test sample, it can be intuitively seen whether the drop voltage of the test instrument with load meets the national requirements. Moreover, the insulation condition of the test sample can be visually observed through the functions of measuring the live voltage and leakage current of the actual test sample.

● Can automatically measure and rememberR_15STheR_60S TheR_10minvalueAutomatically display polarization index（PI）,Induced absorption ratio（DAR）Test values and testing time.

● The anti-interference performance is particularly practical for110KV and above large capacity transformers and long-distance power cables are used in power systems.

● Automatic discharge: Adopting excellent high-voltage discharge technology to quickly discharge capacitive test samples, and measuring the discharge voltage in real time during discharge (the test voltage of the test sample is...)0v）， For high-capacity test samples, due to the absorption of charges by the medium, manual discharge is required to ensure personnel safety.

Internal rechargeable lithium battery or AC power supply, truly dual-purpose AC/DC, does not affect testing accuracy.

The coexistence of analog pointers and digital displays, where the numbers reflect the accuracy of the insulation resistance of the test sample, and analog pointers can reflect the dynamic changes in insulation resistance during the testing process.

● 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.

● Digital display of battery level and protection function for undervoltage alarm.

Intelligent battery charging management can effectively prevent battery overcharging from shortening or damaging battery life.

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

Short circuit protection ensures that the instrument will not be burned out in the event of a short circuit.
