Frequently Asked Questions

How should I prepare a circuit before taking a measurement with this meter?

Always remove power from the device under test and ensure you discharge capacitors before testing to obtain accurate readings.

When should I choose between Parallel (PAL) and Series (SER) mode?

Use parallel mode for measuring high impedances, while series mode is generally used for low impedances.

Which test frequency is best suited for different components?

Generally, use 120Hz for large electrolytic capacitors and 1kHz for most other types of measurements.

Does this meter support data recording to a computer?

Yes, it features an RS-232c PC interface that allows you to capture readings for storage and exporting.
