HZ3151 5kV Insulation Resistance Measurement Device
The insulation resistance tester is widely used across the power, communication, and industrial sectors, where ensuring electrical safety is of paramount importance. By providing accurate insulation resistance measurements, the instrument helps detect insulation deterioration, moisture ingress, and other potential hazards, supporting safe and reliable operation of electrical systems and equipment in these critical industries.
Test Functions
Insulation Resistance (IR)
Dielectric Absorption Ratio (DAR)
Polarization Index (PI)
Dielectric Discharge Rate (DD)
Step Voltage (SV) test
DAR Calculation Modes
Dielectric Absorption Ratio (DAR) Modes
The instrument supports two DAR calculation modes: R600s / R30s and R600s / R15s, providing flexibility to meet different testing standards and application requirements.
Voltage Measurement Functions
Integrated DC and AC voltmeter functions automatically identify DC and AC voltage signals, and measure the frequency of AC voltage signals, expanding the instrument's diagnostic capabilities.
Cable Length Measurement
The tester includes the capability to measure cable length, adding further utility for field applications.
Anti-Interference Performance
Controllable hardware filters and configurable software filters work together to significantly improve the instrument's anti-interference performance, ensuring reliable measurements in electrically noisy environments.
Independent Test Time Memory
Test times for different test modes are saved independently without mutual interference, making subsequent testing more convenient and reducing setup time.
Automatic Shutdown
The instrument features automatic shutdown when idle or when the battery is low. The shutdown time is user-configurable, providing flexibility to suit different usage patterns.
Data Storage & Firmware Upgrade
USB storage function enables batch export of test data for convenient record-keeping and analysis. Firmware upgrades for both the main control unit and high-voltage power supply can be performed via USB, ensuring the instrument remains up-to-date with the latest features and improvements.
Communication Interfaces
The instrument is equipped with an RS232 communication interface (RS485 optional) and Bluetooth communication function, facilitating data transfer and remote control.
Power Supply
A built-in high-capacity lithium battery and fast charger provide extended field operation. Both the instrument panel and LCD screen display the current charging status for user convenience.
