The Digital Multimeter and its Functions:
OFF
: On- / Off-switch.
HOLD
: Hold the current value.
BACKLIGHT
: Backlight of the display.
V=
: DC voltage measurement. The value will be displayed in V
[Volt].
A=
: DC current measurement. The value will be displayed in A
[Ampere].
hFE
: Transistor test.
: At the diode testing the forward bias through a diode will be
shown in V.
: At the continuity testing sounds an acoustic signal if the electric
resistance is < 50
Ω
.
Ω
: Measurement of electric resistance. The value will be displayed
in
Ω
[Ohm].
̰
V~
: AC voltage measurement. The value will be displayed in V
[Volt].
: Rotary Switch.
10 A
: Connector for the red test lead if the current to be measured
is between 200 mA and 10 A. Attention: A measuring procedure
should not be longer than 10 s.
V
Ω
mA
: Connector for the red test lead for voltage and resistance
measurements and if the current to be measured is between 2 µA
and 200 mA.
COM
: Connector for the black test lead.
The Procedures of Measurement:
DC Voltage Measurement:
1.
Connect the red test lead with
V
Ω
mA
and the black one with
COM
.
2.
Turn the rotary switch to
V=
.
3.
Adjust the metering range. If you do not know the range in the first place choose the highest range
position and change it down until you can read a meaningful value on the display.
4.
Connect the heads of the test leads to the poles of the test object.
5.
Now the display shows the value of the voltage together with its polarity (as algebraic sign).
Resolution: max. 100
µ
V
Accuracy: max. +/- (1.0% + 2 digits)
