Smart Measurement Mode
The device features a smart measurement mode, through which the device can
automatically choose and determine which measurement function use, without the
operator choosing it manually. The smart measurement mode is enabled by default
when turning on the device. The mode is applicable for AC/DC voltage, resistance, and
continuity measurement.
Note: Minimum measurable voltage: 0.5V AC; 0,8V DC
1. Press the button to turn on the device. The display will show , indicating
that the smart measurement mode is enabled
2. Insert the red probe into the input socket and the black probe into the
"COM" input socket. Let the probe’s tips touch one another, to check whether they
are correctly connected. The indicator light should turn green and the buzzer sound.
3. Connect the probes’ tips (red probe is the positive pole, black probe is the negative
pole) in parallel to voltage source / resistor and the device will automatically
recognize the signal and choose the correct measurement function.
4. When Measuring AC voltage, the frequency will be displayed at the same time.
5. When the measured resistance is less than 50Ω, the buzzer will sound and the
indicator light will turn green. The device switches to continuity testing.
6. Results will be shown on the screen of the device.
