MASTECH MS2115A Clamp Meter True RMS

The MASTECH MS2115A is a digital clamp meter with True RMS capability for AC voltage and AC current measurement. It handles DC and AC current up to 1000A using a 40mm jaw opening. The LCD provides 5999 counts resolution across multiple measurement functions including voltage, resistance, capacitance, frequency and duty cycle.

Installation ease and common issues

Operation requires only opening the jaw around a single conductor and selecting the correct function via the rotary switch. The built-in non-contact voltage detector adds a quick safety check before contact. The main error source is clamping around multiple conductors simultaneously, which cancels the magnetic field and gives a zero or incorrect reading.

Pre-order setup checks

Confirm the 40mm jaw opening fits the conductors you intend to measure, especially bundled cables or large busbars. Verify that the expected current levels fall within the 40A and 400A ranges with their stated accuracy. Ensure you have a 9V battery available as none is supplied in the package.

Questions about this item

How can I confirm the MS2115A is measuring AC correctly after setup?

Select an AC voltage or current range and verify the True RMS reading on the 5999-count LCD matches a known source.

What accessories come with the MS2115A and what must I supply?

The box includes the clamp meter, test leads, English manual and a pouch; you must provide the battery.

Which current range on the MS2115A suits a 400 A load?

Use the 400 A AC or DC current range, which measures up to 400 A with ±2% accuracy.
