help Mastech MS8688B FAQ
Is the Mastech MS8688B True RMS?
No, the MS8688B is not a True RMS multimeter. It uses average responding measurement, which may not accurately read non-sinusoidal waveforms commonly found in variable frequency drives or switching power supplies.
What is the maximum voltage the MS8688B can measure?
The MS8688B can measure DC and AC voltages up to 400V in the primary ranges. It has a 600V rating for higher voltage applications, making it suitable for most residential and light commercial electrical work.
Does this multimeter measure temperature?
No, the MS8688B does not include a temperature measurement function. For temperature readings, you would need to purchase a separate thermometer or upgrade to a multimeter model with K-type thermocouple input.
What safety rating does the MS8688B have?
The MS8688B carries a CAT III 600V safety rating, meaning it's designed for testing in building wiring and fixed industrial installations, providing adequate protection against voltage transients in those environments.
Can I use the MS8688B for automotive diagnostics?
Yes, for basic automotive diagnostics including battery voltage, wiring continuity, and diode testing. However, it lacks temperature measurement and may have limited range for some high-current automotive testing applications.
