Velleman DVM030 Bedienungsanleitung Seite 6

• Set the range selector at its highest position if the intensity of the
charge to be measured is unknown beforehand.
• Disconnect the test leads from the tested circuit before rotating
the range selector in order to change functions.
• When carrying out measurements on a TV set or switching power
circuits, always remember that the meter may be damaged by
any high amplitude voltage pulses at test points.
• Always be careful when working with voltages above 60 VDC or
30 VAC rms. Keep your fingers behind the probe barriers at all
times during measurement.
• Never perform resistance, diode or continuity measurements on
live circuits. Make sure all capacitors in the circuit are depleted.
6. General Description
Refer to the illustration on page 2 of this manual:
1. Non-contact Voltage (NCV) induction position
2. LED indicator
3. Illuminated LCD Display
4. Function buttons
5. Rotaty switch
6. "A" jack
Insert the red test lead in this connector in order to measure a max.
current of 10 A.
7. "µA/mA" jack
Insert the red test lead in this connector in order to measure a max.
current of 500 mA.
8. "V hFE
Insert the red (positive) test lead in this connector to measure voltage
and resistance.
Or insert the black test plug between "V
jack for capacitance or hFE measurements.
9. "COM" jack
Insert the black (negative) test lead.
7. Overvoltage/Installation Category
DMMs are categorized depending on the risk and severity of transient
overvoltage that might occur at the point of test. Transients are short-lived
bursts of energy induced in a system, e.g. caused by lightning strike on a
power line.
