Resistance Measurement - Velleman DVM892N Bedienungsanleitung

11.2 AC CURRENT MEASUREMENT
1. Connect the red test lead to the "mA/BATT/°C" jack and the black test
lead to the "COM" jack (switch the red lead to the "15A" jack for
measurements between 200 mA and 15 A).
2. Set the rotary switch in the desired A~ position.
3. Open the circuit in which the current is to be measured and connect
the test leads to the circuit IN SERIES.
4. Read the current value and the polarity of the red lead connection on
the LCD display

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 (the red lead has a positive polarity "+").
2. Set the rotary switch in the appropriate "" range position.
3. Connect the test leads to the resistor to be measured and read the
LCD display.
4. 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 and Continuity 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 (the red lead has a positive polarity "+".).
2. Set the rotary switch in the "
3. 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. If the connection is
reversed, the display will merely show a "1".
For continuity testing, if continuity exists, the built-in buzzer will
sound.
