3-3/4 True-RMS Auto Range Multimeter

Q: Can I switch from auto to manual range on the MT-1710N?
A: Yes, you can switch between auto and manual range using the RANGE button.

• By default, the meter starts in Auto Range Mode, indicated by “AUTO” on the screen.

• To switch to Manual Range Mode, short press the RANGE button. The “AUTO” icon will disappear.

• In Manual Mode, the meter starts from the lowest range. Each short press of the RANGE button will cycle through the next available range.

• To return to Auto Range Mode, press and hold the RANGE button until the “AUTO” icon reappears.

 

 

If you're comparing this meter with a standard multimeter, keep in mind that most basic models calculate voltage using average or peak values, which are only accurate for pure sine waves.

However, in real-world applications—like measuring outputs from thyristor-controlled rectifiers or inverters (non-sine waveforms)—those meters can be significantly inaccurate.

The MT-1710N, like the MT-1707N, is a True RMS multimeter, allowing it to deliver accurate readings even for non-sinusoidal waveforms.

The MT-1710N is a 3-3/4-digit, 3999-count true-RMS auto-ranging multimeter featuring high-capacitance measurement, non-contact voltage detection, and live/neutral wire identification. It is suitable for general electrical inspection, electronics repair, and work requiring quick switching among measurement functions.

The MT-1710N is suitable for electricians, equipment maintenance, electronics projects, and users with basic electrical knowledge. It can handle common voltage, current, resistance, capacitance, frequency, temperature, diode, and continuity measurements. For household use, it should still be operated by someone who understands measurement safety and correct connections.

True-RMS measurement improves the usefulness of readings for non-sinusoidal AC signals, such as distorted waveforms produced by variable-frequency drives, rectifier controls, or certain electronic equipment. A meter that calculates readings only from an average value may show a more noticeable error for these waveforms.

The capacitance range of up to 100 mF can be used to check higher-capacitance components in power supplies, household appliances, and electronic equipment. Before measurement, fully discharge the capacitor and isolate it from the circuit to prevent residual voltage from causing inaccurate readings or damaging the meter.

NCV senses whether an AC electric field may be present nearby without contact and is useful for an initial search for energized wiring. Live/neutral wire identification helps determine the live and neutral conductors of an outlet or wire. Both are auxiliary indications; use the correct measurement method to confirm the condition before formal work.

Yes. Auto-ranging is the default when the meter is turned on. Briefly press the RANGE button to switch to manual ranging and select ranges step by step; press and hold the RANGE button to return to auto-ranging. Auto-ranging is convenient for quick checks, while manual ranging is useful for fixing the display range or observing small changes.

The MT-1710N can measure AC/DC voltage, AC/DC current, resistance, capacitance, frequency, temperature, diodes, and continuity. It also provides auxiliary functions such as relative measurement and data hold. Before use, confirm that the test leads are in the correct jacks and that the rotary switch is set for the intended measurement.

Yes. The MT-1710N has a display backlight and a rear work light to help users read the display and identify test points inside distribution boxes, machinery, or other poorly lit areas. The lighting is only an operating aid; ensure the work area is safe and do not risk contact with energized parts when visibility is inadequate.

When measuring current, the red test lead must be inserted into the appropriate microamp/milliamp or ampere input. Move it back to the voltage/resistance input immediately after completing the measurement. Connecting the meter directly across a voltage source while the lead remains in a current input may cause a short circuit, blow the fuse, or create a risk of personal injury.

Choose the MT-1710N when the priority is routine electrical testing, high-capacitance measurement, NCV, and live/neutral wire identification. If you need to export continuous measurement data to a computer, create graphs, or prepare laboratory reports, select a model with USB connectivity and software-based recording.
