measurements

2 Safety Notes

This appliance corresponds to the direc-
tive for electromagnetic compatibility
89/336/EEC and the low voltage direc-
tive 73/23/EEC.
With this unit very high voltages dan-
gerous to life can be measured. Be
especially careful with voltage meas-
urements above 42 V. The test leads
must always be perfectly insulated.
Damaged test leads must be replaced.
Always watch the following items regard-
ing the operation:
The unit is only suitable for indoor use.
Protect the unit from humidity and heat
(permissible ambient temperature range
0–40 °C).
If the unit is used for purposes other
than originally intended, if it is over-
loaded or operated, connected or re-
paired in the wrong way, there is no lia-
bility for possible damage.
8
Only use a dry, soft cloth for cleaning,
by no means chemicals or water.
If the unit is to be put out of operation
definitively, bring it to a local recycling
plant for disposal.
3 Applications
With this digital multimeter DC and AC
voltages, DC and AC currents as well as
resistances can be measured. Further-
more, the forward voltage of diodes and
the current amplification (hFE) of transis-
tors can be measured. For the continuity
measurement a buzzer is provided.

4 Setting into Operation

1) Set the rotary switch (3) to the desired
measuring range. With model DMT-
2560 switch on the unit additionally
with the ON/OFF switch (2).
2) A display is shown. If not, a 9 V battery
must be inserted. If the symbol
displayed, replace the battery — see
chapter 6 "Replacing of Battery or
Fuse".
3) After the operation always switch off
the unit, otherwise the battery will be
exhausted unnecessarily:
DMT-2505 with the rotary switch (3)
(position "OFF")
DMT-2560 with the ON/OFF switch
(2). This model also switches off auto-
matically if it is not used for approx.
30 minutes.
5 Carrying out Measure-
ments
Always plug the black test lead into the
black jack "COM" (7) and the red test
lead into one of the three other jack
according to the measurement.
For a high accuracy always choose
the lowest possible measuring range
(e. g. measure 15 V in the 20 V range and
not in the 200 V range). If a measuring
range has been exceeded, the unit sig-
nalizes "1" or "-1". In this case choose
the next higher range.
