Frequently Asked Questions - MTX 203 METRIX

How to measure AC or DC voltage with the MTX 203?

Turn the rotary switch to V≈ (10 MΩ) or VLowZ≈ (500 kΩ). To switch between AC and DC, press the yellow button. Connect the red probe to the + terminal and the black probe to COM. Place the probes on the test points.

How to use the non-contact voltage detection (NCV)?

Disconnect the probes, turn the switch to NCV. Bring the live conductor (230 V, 50 Hz) near the display. The device emits beeps and the backlight flashes red if voltage is detected. Caution: NCV is indicative, does not replace a contact measurement.

What does the 'OL' display mean on the MTX 203?

'OL' stands for 'Over Load'. It indicates that the measured value exceeds the range capacity of the device in the selected range. For example, resistance above 60 MΩ, or voltage beyond the range.

How to replace the batteries of the MTX 203?

Disconnect all test leads. Loosen the 2 screws of the battery compartment cover on the back. Replace the batteries with 2 × 1.5 V AA (LR6) batteries, respecting polarity. Retighten the cover.

How to test the fuses of the MTX 203?

Turn the switch to Ω position, press the yellow button. Connect a lead to the + terminal and apply the probe to the A or mA/μA input depending on the fuse. A good fuse displays between 000.0 Ω and 000.2 Ω. If 'OL' appears, replace the fuse.

What is the measurement category of the MTX 203?

The MTX 203 complies with category CAT III 600 V according to IEC 61010-1. This allows measurements on low-voltage building installation circuits (distribution boards, circuit breakers, wiring).

How to measure continuity with the MTX 203?

Ensure the circuit is de-energized. Turn the switch to the Ω/continuity position. Continuity mode is selected by default. Connect the red probe to + and black to COM. Apply the probes: a beep sounds if the resistance is less than 50 Ω.

How to measure capacitance with the MTX 203?

Circuit de-energized and discharged. Turn the switch to the Ω/continuity/diode/capacitance position, then press the yellow button three times to select capacitance. Connect the leads (red to +, black to COM) to the capacitor terminals. Read the stabilized value.

What is the VLowZ function used for?

The VLowZ position measures AC voltage with reduced impedance (500 kΩ instead of 10 MΩ). It helps avoid 'ghost' voltages (induced voltages) and gives a more reliable indication of the presence of real voltage.

How to clean the MTX 203?

Use a damp cloth with water and mild detergent. Do not use abrasive products or solvents. Dry the device thoroughly before use. If the terminals are dirty or wet, it may affect measurements.
