Frequently Asked Questions About the VS-528 Automotive Multimeter
Can the VS-528 measure RPM from ignition signals?
Yes. The VS-528 supports RPM measurement from ignition coils or distributor systems, making it ideal for engine diagnostics, tuning, and troubleshooting.
Is this multimeter suitable for hybrid or EV systems?
The CAT IV 1000V safety rating makes it capable of testing high-voltage circuits typically found in electric and hybrid vehicles. However, always ensure you are following the appropriate safety protocols when testing EV systems.
What is True RMS, and why does it matter?
True RMS (Root Mean Square) technology allows the VS-528 to provide accurate readings on non-sinusoidal signals such as those created by inverters or switching circuits. This is especially important in automotive systems where many signals are not purely sinusoidal.
Can I use this multimeter with external clamps?
Yes. The VS-528 is compatible with both low current and large current AC/DC clamp probes, extending its measurement capabilities beyond what standard test leads can provide.
Does the multimeter come with a warranty?
Yes, the VS-528 typically comes with a manufacturer’s warranty. For more specific warranty coverage, check with Power Start at the time of purchase or refer to the documentation supplied with the unit.
