Peak detection
The voltage peak can be checked in this mode. Use the mode select button to change to the “+/-” mode and set the maximum per-
mitted voltage by pressing the mode select button. The possible settings are 0.5 V, 1 V, 2 V, 5 V, 10 V and 48 V. With the required
target value set, apply electrical current to the corresponding lead with the test probe. The instrument emits an acoustic signal when
the set value is exceeded. A change is then made to the next higher setting and no further sounds should come from the instru-
ment.
Example: A 12 V maximum is to be applied to the lead. The instrument is set to 10 V and checked. As the 10
V have been exceeded, a sound is heard from the instrument. The next higher range is now chosen (48 V)
and the signal is silenced.
Cleaning
Use a damp cloth and mild household detergent to clean the instrument should it become soiled through daily use. Never use ag-
gressive cleaning agents or solvents to clean the instrument.
To avoid electric shocks, do not allow moisture to penetrate the housing.
Maintenance
The instrument does not require special maintenance when used as specified in this operating manual.
