    Technical Note: The specifications and standards above are based on the supplier’s product information. Confirm the exact model, applicable certification, measurement category and operating instructions against the manufacturer’s current documentation before use.

    Important: The listed voltage indications are stepped values and should not be interpreted as a confirmed precision measurement specification. GS38 is HSE guidance rather than a product certification.

    Why Choose This EV High Voltage Tester?

    01 – Wide Voltage Detection Range

    Supports contact voltage testing across the supplier-stated 12–1000V AC/DC range.

    02 – Clear Voltage Indication

    The backlit LCD and stepped voltage indicators help technicians read the displayed voltage information.

    03 – Professional Measurement Ratings

    Supplier-stated CAT III 1000V and CAT IV 600V ratings for suitable electrical testing environments.

    04 – EV Workshop Applications

    A practical testing instrument for trained EV and hybrid technicians following approved procedures.

    Typical Applications

    • Electric vehicle electrical maintenance.
    • Hybrid vehicle electrical system testing.
    • Voltage presence checks on compatible circuits.
    • Approved vehicle electrical safe-isolation procedures.
    • Automotive electrical workshop diagnostics.
    • Professional electrical maintenance.
    • Electrical testing within the stated instrument ratings.
    • Technician training under appropriate supervision.

    Application Suitability: Always verify the instrument’s exact ratings, approved applications and manufacturer instructions before testing. Not every EV high-voltage system falls within this tester’s voltage or measurement category limits.

    Safe Use & Electrical Testing

    This voltage tester must be used by suitably trained personnel following the applicable safe system of work.

    1. Check the Instrument: Inspect the tester, leads, probe insulation and accessories for damage.
    2. Confirm Suitability: Verify the voltage range, measurement category and manufacturer’s instructions for the intended system.
    3. Follow Safe Isolation: Identify and isolate the relevant energy sources using the approved procedure.
    4. Prove the Tester: Confirm correct operation using an appropriate proving unit or known suitable source before testing.
    5. Carry Out Approved Testing: Follow the manufacturer’s instructions and the applicable prove-dead procedure for the circuit or vehicle system.
    6. Re-Prove the Tester: Confirm correct operation again after testing and complete the required safety checks before work begins.

    Critical Safety Information: Never assume a system is safe solely because the tester shows no voltage. EV systems can contain stored energy, and voltage may be present outside the instrument’s specified range. Follow manufacturer-approved isolation, discharge, verification and personal protective equipment requirements.

    Safety, Compatibility & Important Information

    • Qualified Users – Intended for suitably trained electrical and EV technicians.
    • Voltage Limits – Never exceed the manufacturer’s stated instrument ratings.
    • Measurement Categories – Select equipment suitable for the electrical environment.
    • Probe Safety – Inspect probes and leads before each use.
    • Proving Procedure – Verify tester operation before and after voltage absence checks.
    • Stored Energy – Follow EV manufacturer procedures for capacitors and high-voltage systems.
    • Personal Protection – Use appropriate PPE and insulated equipment as required.
    • Manufacturer Documentation – Follow the current operating instructions and safety warnings.

    Important: The tester is not a substitute for training, a suitable proving unit, approved isolation procedures or the vehicle manufacturer’s safety requirements.

    Frequently Asked Questions

    Is this voltage tester suitable for electric and hybrid vehicles?

    The tester is marketed for EV and hybrid electrical applications. Suitability depends on the vehicle system voltage, measurement category, approved testing procedure and manufacturer requirements.

    Does the tester measure both AC and DC voltage?

    Yes. The supplier specifies a detection range of 12–1000V AC/DC, with stepped voltage indications and a backlit LCD display.

    What do CAT III 1000V and CAT IV 600V mean?

    These are measurement category ratings relating to the electrical environments and transient overvoltages an instrument is designed to withstand. The appropriate category depends on the installation and testing location.

    Can this tester prove an EV high-voltage system is safe?

    It may form part of an approved prove-dead procedure when its specifications are suitable. A zero-voltage indication alone does not establish safety. Technicians must follow the vehicle manufacturer’s isolation and verification procedures.

    Do I need a separate voltage proving unit?

    An appropriate proving method is required before and after testing. A suitable proving unit is commonly used, but its compatibility with the tester and the applicable safe-isolation procedure must be confirmed.

    Technical Documentation & Operating Instructions

    Before use, refer to the manufacturer’s current operating manual for complete electrical specifications, measurement category ratings, safety instructions and testing procedures.

    Manufacturer Operating Manual

    The operating manual should confirm the instrument’s approved voltage range, test functions, probe requirements and maintenance instructions.

    Electrical Safety & Compliance

    Review the applicable manufacturer conformity documentation and HSE electrical safety guidance before using the instrument for professional safe-isolation work.

    Documentation Note: A verified manufacturer manual or declaration of conformity has not been supplied for this particular tester. Confirm these documents before advertising the instrument as independently certified to the listed standards.
