Caution: Before switching over to another measuring function, always
remove the test tips from the object to be measured to prevent damage
to the meter!
With unknown voltage values or current values, start with the highest
measuring range to prevent overload of the meter. Then select the small-
est possible measuring range (e. g. to measure 15 V
¿
, use the range
“20 V
DC
” instead of the range “200 V
DC
”) to obtain a high accuracy. If a
measuring range is exceeded, “1” will be displayed. In this case, select
the next higher range.
5.1 Measuring voltages
Caution: When measuring voltages, do not connect the red test lead to
the jack “10A” (5), otherwise the meter and the object to be measured
may be damaged!
For measuring AC voltages, set the switch (4) to one of the two ranges
“V
AC
”; for measuring DC voltages, set it to one of the five ranges “V
DC
”.
Apply the test tips to the object to be measured and read the value on the
display. If the red test tip is applied to the negative pole and the black tip
to the positive pole when measuring DC voltages, there will be a minus
sign in front of the value displayed.
5.2 Measuring DC currents
G
The current to be measured must not exceed 10 A!
G
Currents between 200 mA and 10 A must not be measured for more
than 30 seconds. There must be an interval of 15 minutes between the
individual measurements, otherwise the meter and the test leads may
be damaged.
G
Never measure voltages when the red test lead is connected to the jack
“10A” (5), otherwise the meter and the object to be measured may be
damaged!
WARNING: Take into account unexpected voltages on ob-
jects to be measured. Capacitors, for example, may be dan-
gerously charged even if the voltage source has been
switched off.
G
Never use this meter for measuring circuits with corona discharges
(high voltage). Risk of electrocution!
G
The maximum voltage to be measured must not exceed 250 V
