Product Information
Full details
The VOLTCRAFT VC35 Multi-Tester is designed for electricians and technicians working with three-phase systems. Its key benefit is accurately determining the phase sequence or direction of motor rotation without the need for a frequency converter, ensuring safe and correct electrical connections. A minor caveat is its reliance on the live phases for power, meaning it cannot be used on de-energized circuits. This tester confirms the presence of all three phases and features pluggable test leads with alligator clips for easy connection.

FAQs
Do I need batteries for the VOLTCRAFT VC35?
No, the VOLTCRAFT VC35 is powered directly from the connected three-phase network and does not require any batteries.
What is the voltage range for the VC35?
The VC35 can test AC voltages ranging from 40V to 700V.
Can the VC35 be used to test single-phase circuits?
No, the VC35 is specifically designed for testing three-phase AC networks and cannot be used for single-phase circuits.
How do I know if the motor is rotating in the correct direction?
The VC35 will indicate the phase sequence. You need to know the correct rotation for your specific motor and compare it to the tester's indication. If it shows the incorrect sequence, the wiring should be reversed.
What happens if I connect the tester to a de-energized circuit?
The tester will not power on or provide any indication, as it requires power from the live phases to operate.
Are the test leads replaceable?
Yes, the VC35 features pluggable test leads, making them easy to replace if damaged.
Troubleshooting
No indication on the tester.
Verify that the three-phase power source is live and within the operating voltage range (40-700V). Ensure all alligator clips are securely attached to the correct terminals.
Tester indicates incorrect phase rotation.
Double-check the connections to ensure each clip is on the correct phase. Confirm the voltage of the network. If connections are verified, the wiring itself may be incorrect.
Alligator clips are loose.
Ensure the clips are fully pushed onto the terminals. If the terminals are damaged or corroded, clean them or consider alternative connection methods if safe and applicable.
Pros and Cons
Pros
- No batteries required, always ready for use.
- Clearly indicates phase direction, preventing motor damage.
- Simple and straightforward operation.
- Durable construction with pluggable test leads.
- Supports a broad voltage range (40-700V).
Cons
- Requires a live three-phase network to operate.
- Not suitable for single-phase testing.
- Limited to phase rotation testing, not a full multimeter.
- Alligator clips may require careful placement on certain terminals.
Setup, Compatibility & Care
Setup:
- Ensure the three-phase power source is live.
- Connect the three pluggable test leads to the VC35 unit.
- Attach the push-on alligator clips to the corresponding terminals of the three-phase connection (e.g., L1, L2, L3 or U, V, W).
- Observe the indicator on the VC35 to determine the phase sequence.
Compatibility:
The VC35 is designed for use with three-phase AC power networks ranging from 40V to 700V. It is not compatible with single-phase power sources or DC circuits.
Care:
- Keep the tester clean and dry. Wipe with a soft, dry cloth as needed.
- Inspect the test leads and alligator clips for damage before each use.
- Store the unit in the provided carry bag when not in use to protect it from dust and physical damage.
- Avoid exposing the tester to extreme temperatures or moisture.
