Insulation Resistance Meter VS-628

Insulation Resistance Meter VS-628 – High-Voltage Diagnostic Meter for Automotive & EV Applications

The Insulation Resistance Meter VS-628 is a specialised diagnostic tool designed to test insulation integrity in high-voltage components where standard multimeters fall short. It’s the ideal solution for automotive technicians, drivability specialists, and EV professionals who need to detect insulation breakdown in piezo fuel injectors, solenoid injectors, coils, and motor windings.

Unlike a traditional digital multimeter (DMM), the VS-628 applies high voltage (up to 1000V) to simulate real-world operating conditions, allowing you to identify insulation faults that would otherwise go undetected. This unit also includes auto-ranging AC/DC voltmeter and Ohmmeter functionality, making it a compact, multi-purpose addition to any advanced diagnostic setup.

How to Use the Insulation Resistance Meter VS-628

1. Select the Test Function – Choose insulation resistance or multimeter mode based on your diagnostic task. 
2. Set the Test Voltage – Select from 100V, 250V, 500V, or 1000V depending on the component requirements. 
3. Connect Test Leads – Attach the probes to the component under inspection, ensuring a secure connection. 
4. Perform the Test – Activate the unit and monitor the resistance reading. Low readings may indicate insulation failure. 
5. Switch to Voltmeter or Ohmmeter – Use additional functions for voltage checks or continuity testing as needed. 
6. Store Safely After Use – Power down and store the device in a dry, protected space to maintain accuracy.
   

Always follow safety instructions when working with high-voltage equipment.

FAQs about Insulation Resistance Meter VS-628

1. What makes this different from a regular multimeter?
   Unlike regular multimeters that use low test voltages, the VS-628 applies up to 1000V to detect insulation breakdown in high-voltage components. This makes it essential for diagnosing systems in EVs, hybrids, and modern petrol/diesel vehicles.
2. Can I use it on low-voltage automotive systems?
   Yes. The unit allows you to select lower voltages (100V or 250V), making it versatile enough for use on sensitive components without risk of damage.
3. Who should use this meter?
   This tool is ideal for automotive technicians, electrical repair specialists, and those working in EV service centres. It’s designed for professionals who deal with drivability issues and advanced diagnostics.
4. Does it replace my existing DMM?
   No—it complements your DMM by providing high-voltage insulation testing. It also includes AC/DC voltage and resistance testing for added convenience.
5. Is it safe to use on live circuits?
   It is rated CAT IV 600V and CAT III 1000V, but it should not be used on live circuits during insulation resistance testing. Always ensure the system is powered down before testing.
