HZ3151 5kV Insulation Resistance Measurement Device
The insulation resistance tester is widely used in the power, communication, and industrial sectors to ensure electrical safety.
Features
Electrical Safety & Isolation
The instrument adopts a fully isolated power supply scheme. The low-voltage circuit (battery-powered, human-machine interaction circuit) is completely electrically isolated from the high-voltage circuit (NC high-voltage power supply, signal sampling circuit), with an isolation voltage as high as 30 kV, ensuring operator safety.
Display & User Interface
Industrial-grade 7-inch color LCD screen with 1024 × 600 resolution, 85° viewing angle, and 400 cd/m² brightness.
Capacitive touch screen made of explosion-proof glass – excellent operating feel and durable display.
Single-button shuttle function + buttons with color backlight – enhanced operating experience.
Voltage Ranges
Six fixed voltage ranges: 100 V, 250 V, 500 V, 1000 V, 2500 V, 5000 V.
Custom voltage mode: Continuously adjustable from 50 V to 5000 V, with a step voltage of 10 V.
Current & Power
Maximum output short-circuit current: 6 mA (adjustable: 1 mA, 2 mA, 3 mA, 4 mA, 5 mA, 6 mA).
Maximum continuous output power: 25 W.
Discharge Circuit
Independent discharge circuit for rapid discharge of the test object after test completion.
Test Functions
Insulation Resistance (IR)
Dielectric Absorption Ratio (DAR)
Polarization Index (PI)
Dielectric Discharge Rate (DD)
Step Voltage (SV) test
DAR Calculation Modes
Supports two DAR calculation modes: R600s / R30s and R600s / R15s.
Voltage Measurement Functions
DC and AC voltmeter functions – automatically identifies DC and AC voltage signals, and measures AC voltage signal frequency.
Cable Length Measurement
Capable of measuring cable length.
Anti-Interference Performance
Controllable hardware filter and software filter – greatly improves instrument anti-interference performance.
Independent Test Time Memory
Test times for various test modes are saved independently without mutual interference, convenient for next use.
Automatic Shutdown
Automatic shutdown when idle and when battery is low – user-configurable shutdown time.
Data Storage & Firmware Upgrade
USB storage function – test data can be exported in batches.
Supports firmware upgrade for both main control unit and high-voltage power supply via USB.
Communication Interfaces
RS232 (RS485 optional) communication interface.
Bluetooth communication function.
Power Supply
Built-in high-capacity lithium battery and fast charger. Both the instrument panel and LCD screen indicate current charging status.
