Fault Finding; Performing Measurements - Conrad VC 350E Bedienungsanleitung

Between each individual measurement cycle, a battery check is
carried out.
b) All other symbols, which stand for the various units of measu-
rement:
AC = Alternating Current
DC = Direct Current
mV = Millivolt (exp.-3)
V = Volt
uA = Micro-Ampere (exp.-6)
mA = Milliampere (exp.-3)
A = Ampere
kHz = Kilohertz (exp.3)
MHz = Megahertz (exp.6)
°C = Degrees Celsius
°F = Degrees Fahrenheit
uF = Microfarad (exp.-6)
nF = Nanofarad (exp.-9)
kΩ = Kiloohm (exp.3)
MΩ = Megaohm (exp.6)
5.5 Fault finding
If the multimeter is not functioning correctly, the following causes
may be responsible:

Cause
Measuring instrument
not operating
The battery is in order, but
no current measurement
possible

6. Performing measurements

General:
The multimeter is not protected against the test leads being
connected to the wrong measuring socket as a function of the res-
pective measurement function. It can be damaged or destroyed.
To safeguard against this, a so-called acoustic socket alarm is built
into this multimeter, which together with the selected measure-
ment function (voltage, frequency, resistance or capacity measure-
ment, etc.) reproduces various signal sequences. If for example the
red test lead is in one of the current measurement sockets (uA/mA
or A) and the black test lead in the COM socket but the rotary
switch is not set for current measurement, then the following
acoustic signals are hear:
V AC/DC : ——————— (continuous tone)
mV DC/FREQ : - - - - - - - - ("slowly"-interrupted tone)
Ohm / /->l- : - - - - - - - - - - -
CAP :
Note
Should other test leads be used instead of those supplied with
the measuring instrument, the socket alarm does not function.
Remedy
Read through the operating
instructions thoroughly.
Is the battery unused?
Are the fuses in order?
Check the fuse(s) per 5.1.2. Are the
fuses clipped in the holder(s)?
("quickly"-interrupted tone)
(no acoustic signal)
