 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
This device is a battery-operated, hand-held 3 ½ digital multi-meter for
measuring DC and AC voltages, DC current and resistance. It also offers the
possibility of executing continuity tests and of testing diodes and transistors.
The back light is optional.
Refer to the illustration on page 2 of this manual:
1. Display
3 ½ digits, 7 segments, LCD: 61 x 26 mm
2. On-off
3. Rotary switch
This switch is used to select functions and desired ranges as well as to
turn the meter on/off.
4. Hold button
In any range, press this button to freeze the last reading. Press again
to unfreeze.
5. "15A" jack
Insert the red test lead in this connector in order to measure a max.
current of 15 A.
6. "mA/BATT/°C" jack
Insert the red test lead in this connector in order to measure current
(except 15 A), the battery and temperature.
7. "COM" jack
Insert the black (negative) test lead.
8. "V" jack
Insert the red (positive) test lead in this connector to measure voltage
and resistance.
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.
The existing categories according EN 61010-1 are:
A CAT I-rated meter is suitable for measurements on protected
CAT I electronic circuits that are not directly connected to mains power,
e.g. electronics circuits, control signals...
