Customer Questions & Answers

What advantages does the True RMS function on the Mastech MS8040 offer compared with multimeters that only use average values?

The True RMS function allows accurate measurement of AC voltage and current signals that are not pure sine waves, which is essential in industrial environments with non-linear loads. Multimeters that only calculate average values can produce significant errors when measuring distorted waveforms. The MS8040 ensures realistic results under these conditions.

What are the dimensions and weight of the MS8040, and what accessories are included in the box?

The Mastech MS8040 multimeter has approximate dimensions of 270 mm x 200 mm x 90 mm and a weight of around 1.9 kg. The box includes: the multimeter, standard test leads, K-type temperature probe, RS232 connection cable and user manual.

What maintenance does the instrument require and how can long-term accuracy be ensured?

The main maintenance is to keep the terminals and test leads free from dust and residue, store the unit in a dry environment and check calibration annually. To maintain the specified accuracy (<0.05% on DC), it is recommended to calibrate it every 12 months at an authorised laboratory.

What limitations does it have when measuring AC current, and how do the specifications affect professional use?

The MS8040 measures up to 10 A AC with an accuracy of ±2% and uses a 1 kHz low-pass filter, which limits accurate measurement of currents with higher-frequency components. For loads with greater harmonic content or higher frequencies, a wider-bandwidth instrument may be required. This should be taken into account in specialised industrial applications.

Can the Mastech MS8040 be connected to a computer?

Yes, the multimeter has an RS232 interface and compatible software for Windows PCs, and it can also be connected via USB using a USB serial cable.

What voltage ranges can the MS8040 measure?

It can measure DC voltages from 220 mV to 1000 V with an accuracy of ±0.05% and True RMS AC voltages from 220 mV to 700 V with an accuracy of ±0.6%.

Is it suitable for temperature measurements?

Yes, the MS8040 measures temperatures from -30°C to 1000°C with an accuracy of ±0.2°C.

What power supply does this multimeter require?

The Mastech MS8040 operates on a 220V AC power supply at 50Hz.

What safety rating does this multimeter offer?

It is designed in accordance with IEC61010-1 CAT II 1000V / CAT III 600V, ensuring safety in high-voltage measurements.
