Product Features

1. 5 Selectable Test Voltages for Versatile Applications

The TS58 offers five selectable output voltage levels — 50V, 100V, 250V, 500V, and 1000V — allowing you to choose the appropriate test voltage for different insulation resistance measurement requirements across various electrical equipment and insulation materials.

2. Wide Insulation Resistance Measurement Range

Measures insulation resistance from 0.1MΩ up to 20GΩ, making it suitable for testing large transformers, motors, generators, high-voltage motors, power capacitors, power cables, arresters, and other electrical equipment.

3. AC/DC Dual Voltage Measurement Function

In addition to insulation resistance testing, the TS58 can measure both AC and DC voltages from 10V to 600V, with AC voltage frequency range of 40Hz to 70Hz, offering a comprehensive testing solution in one instrument.

4. DAR and PI Measurement for Insulation Quality Assessment

The instrument automatically calculates the Dielectric Absorption Ratio (DAR) — the ratio of insulation resistance at 1 minute to that at 30 seconds — and the Polarization Index (PI) — the ratio at 10 minutes to that at 1 minute. These measurements help eliminate the effects of temperature, humidity, and interference current, allowing you to accurately judge insulation quality, aging conditions, and moisture levels.

5. 2000-Count Display with Bar Graph and Backlight

Features a large LCD display with a maximum of 2000 counts and a bar graph, making data reading easy even in low-light conditions. The backlight function ensures clear visibility in dimly lit work environments.

6. 100 Groups Data Storage with Read and Recall Functions

Built-in data storage capacity for up to 100 measurement records, with convenient data storage, reading, and deletion functions for efficient data management and record-keeping.

7. Comprehensive Safety Protection Features

Complete protection circuit design — not afraid of voltage counterattack and output short circuit protection. Red LED high voltage indication alerts operators when high voltage is being output, ensuring user safety. Low battery voltage indication reminds you to replace batteries in time.

8. Auto Discharge Function

After each insulation resistance measurement, the instrument automatically discharges the stored capacitance of the circuit under test, protecting both the operator and the equipment from electric shock hazards.

9. Strong Load Capacity with High Output Current

Output short-circuit current of less than 1.8mA provides strong load capacity, ensuring stable and reliable measurements even under demanding test conditions.

10. Dustproof and Moistureproof Design for Outdoor Operation

Built with a dustproof and moistureproof structure, the TS58 is designed to withstand harsh working conditions and is suitable for outdoor field operations.

11. Wide Range of Applications

Ideal for maintenance, repair, testing, and verification of electrical systems and components, including transformers, motors, generators, cables, switches, electrical appliances, and various insulation materials.
