This state-of-the-art insulation tester offers a wide range of measurement parameters, setting it apart as a multi-functional device essential for electrical professionals. It accurately measures Insulation resistance, a fundamental check for electrical safety and system integrity, alongside PV insulation resistance, a specialized capability crucial for solar installations. Furthermore, it can precisely measure Leakage current, identifying even minute current flows that could indicate insulation breakdown or safety hazards. The device also includes standard Voltage measurement capabilities and a unique Capacitance (DD function) for diagnosing capacitive elements within electrical circuits. This extensive suite of measurement functions provides technicians with a holistic view of system health, enabling thorough diagnostics and preventive maintenance.

High Voltage Capacity and Environmental Resilience

Designed for demanding electrical environments, this insulation tester boasts impressive voltage ratings and environmental resilience. It has a maximum rated voltage to terminals of 1000 V AC and a robust 2000 V DC, allowing it to safely handle high-voltage applications common in industrial settings and large-scale solar farms. Its maximum rated voltage to ground is 1000 V (CAT IV) and 600 V (CAT III), ensuring compliance with stringent safety standards for various installation categories. The instrument operates reliably across a wide temperature range, from -20°C to 50°C, and can be stored from -25°C to 65°C, making it suitable for diverse climates. Its IP40 dustproof/waterproof rating (with protector attached) offers protection against solid objects and splashes, while the included Carrying Case C0212 provides IP65 protection, ensuring durability in challenging field conditions.

Specialized PV Insulation Resistance Testing

With the booming solar industry, the specific needs of photovoltaic (PV) systems demand specialized tools. This insulation tester excels in PV insulation resistance measurements, offering critical capabilities for solar professionals. It provides a flexible test voltage range of DC 250 V to 2.00 kV, with convenient presets at 500 V, 1 kV, and 1.5 kV. Users can also set custom test voltages in precise increments: 10 V increments from 250 V to 1 kV, and 25 V increments from 1 kV to 2 kV. The device ensures high accuracy across various ranges, for instance, ±5% reading ±5 digits for up to 20.0 GΩ at 1.5 kV, and ±20% reading for higher ranges up to 100 GΩ. It has a rated current based on the test voltage divided by 20 MΩ and a short-circuit current of 2 mA or less, all while performing 1000 measurements or more on a single set of fully-charged batteries, ensuring extended field operation.

Comprehensive General Insulation Resistance Measurement

Beyond its PV-specific functions, this instrument also delivers robust capabilities for general insulation resistance measurement across a broad spectrum of electrical applications. It offers an even wider test voltage range of DC 250 V to 5.20 kV DC, allowing for thorough testing of various electrical equipment and cabling. Similar to its PV counterpart, it provides user-set test voltages in fine increments and includes convenient presets at 250 V, 500 V, 1000 V, 2500 V, and 5000 V. The accuracy for general insulation resistance is equally impressive, with ±5% reading ±5 digits for ranges like 0.00 MΩ to 50.0 GΩ at 5000 V, extending up to 10.00 TΩ with ±20% accuracy for higher ranges. It operates with a rated current of 1 mA to 1.2 mA and a short-circuit current of 2 mA or less, supporting 200 measurements or more on a single battery charge. These capabilities make it an indispensable tool for routine electrical maintenance, troubleshooting, and compliance verification in commercial and industrial settings.

Advanced Diagnostic Functions and Features

This insulation tester is equipped with advanced diagnostic functions that go beyond simple resistance readings. For insulation diagnosis, it supports key tests like Polarization Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), Step Voltage (SV), Ramp, and a Timer function. These functions help evaluate the quality of insulation over time and under varying stress, providing crucial insights into insulation degradation. Additional features include a battery charge indicator, live circuit indicator for safety, automatic power save for efficiency, and automatic discharge after testing. A backlight ensures visibility in all conditions, while buzzer sounds provide audible feedback. It also supports manual recording and logging recording, temperature and humidity input, elapsed time display, a clock, filter options (including hardware filter), data-hold, system reset, USB communication (with DT4900-01), and wireless communication (with Z3210), making data management and analysis highly efficient. The comparator function aids in quick pass/fail judgments, and features like breakdown cut-off and negative voltage notification enhance safety during high-voltage testing.

Seamless Wireless Connectivity for Modern Workflows

Embracing modern technological demands, this insulation tester offers seamless wireless communication capabilities when the Wireless Adapter Z3210 is installed. This integration enables efficient data transfer, allowing technicians to send measurement data wirelessly to compatible devices for analysis and reporting. This feature significantly enhances workflow efficiency by minimizing manual data entry, reducing errors, and enabling immediate sharing of critical test results with colleagues or clients. The ability to integrate with digital platforms streamlines the entire inspection and reporting process, making it a truly future-ready instrument for professionals who rely on efficient data management in their daily operations.
