Safety & Usage Warnings
- Discontinue use if the instrument is damaged or bare metal parts are exposed.
- Do not press function buttons while test leads are connected and the circuit is live — exit measurement mode before changing test functions.
- Do not replace batteries while the instrument is wet; ensure it is completely dry before use or storage.
- Always confirm test leads are securely connected before measuring.
- Turn the instrument off before opening the battery compartment.
- Do not use abrasive cleaners or solvents on the housing; clean with a soft damp cloth only.
Care & Storage
When storing the TS58 for extended periods, remove the batteries to prevent electrolyte leakage. Store in a clean, dry, well-ventilated location free from dust and corrosive gases, within the storage temperature range of -10°C to +50°C and relative humidity below 75% RH.

Frequently Asked Questions
Q: What output voltages does the HYTAIS TS58 Megohmmeter support?
A: The TS58 supports five selectable output test voltages: 50V, 100V, 250V, 500V, and 1000V, covering a wide range of insulation testing requirements for motors, cables, transformers, and other electrical equipment.
Q: Does the HYTAIS TS58 insulation resistance tester come with batteries?
A: No, batteries are not included. The TS58 requires 8 × AA 1.5V batteries (purchased separately) to operate. This battery-powered design makes it fully portable and suitable for outdoor and remote field testing.
Q: How many measurements can the TS58 store, and how is data retrieved?
A: The TS58 features onboard data storage for up to 100 groups of measurement results. This allows technicians to record readings during field inspections and review them later for documentation, reporting, or trend analysis directly from the instrument's HD backlit LCD display.
Q: Is the HYTAIS TS58 safe to use on energized circuits?
A: The TS58 is designed for insulation resistance testing and AC/DC voltage measurement only. It complies with IEC1010-1 safety standards and features double insulation, short-circuit protection, and voltage counter-attack protection. Always follow proper electrical safety procedures. For energized circuit work, consult applicable safety guidelines such as those published by OSHA.
Q: What is the resistance measurement range of the TS58 Megohmmeter?
A: The HYTAIS TS58 measures insulation resistance from 0.1MΩ up to 20GΩ, making it suitable for testing high-quality insulation in modern electrical equipment including large transformers, generators, power cables, and industrial electrical systems.
