Resistance Measurement; Diode Testing; Range Selection - Velleman DVM101 User Manual

12. Resistance Measurement

Do not conduct resistance measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
1. Connect the red test lead to the "V" jack and the black test lead to
the "COM" jack.
2. Connect the test leads to the resistor to be measured and read the
LCD display.
3. If the resistance being measured is connected to a circuit, turn off the
power and discharge all capacitors before applying the test probes.

13. Diode Testing

Do not conduct diode or continuity measurements on live circuits.
Make sure all capacitors in the circuit are depleted.
1. Connect the red test lead to "V" jack and the black one to the "COM"
jack.
2. Press "SELECT" and select diode or continuity measurement.
3. For measuring diode, connect the red test lead to the anode of the
diode to be tested and the black test lead to the cathode of the diode.
The approx. forward voltage drop of the diode will be displayed.
For measuring continuity, connect the test leads to two points of the
circuit to be tested. If continuity exists, the built-in buzzer will sound.
14. Data and Max Hold
Press "DH" to lock the displayed value. Press again to exit.
Press "MH" to lock the displayed maximum value. Press again to exit.

15. Range Selection

This multimeter will automatically select the proper range. However, it may
be faster to manually select the range.
Repeatedly press "RANGE" to select the desired range. Hold the button
pressed for 2 seconds to go back to automatic range selection.
16. Backlight
Hold the backlight button pressed for 2 seconds to switch the backlight on or
off. The backlight will also switch off automatically.
