9.0 Deleting stored Measurement Data / 

Display of All Memory Entries

Possibility to delete data by using key „Clear" (21).
Furthermore, it is possible to display the total num-
ber of measurement value entries on the display:

Display of Total Number of Measurement Value
Entries:

Set function switch (17) to one of the 5 measu-
rement ranges

Briefly press the key „Clear" (21). A short beep
signal is audible

The total number of all measurement values
saved is displayed

The display disappears after 2 seconds

Delete the Last Memorised Measurement Value:

Set function switch (17) to one of the 5 func-
tions

Press  key „Clear" (21) for approx. 2 seconds.

A short beep signal is audible

After 2 seconds, a further beep signal is audible
and the number of the remaining stored data is
displayed

Get down from the key “Clear” (21)

Deleting all Stored Measurement Values:

Set function switch (17) to one of the 5 func-
tions

Press  key „Clear" (21) for approx. 5 seconds.

Three short beep signals are audible.

„0" appears on the display. The memory is com-
pletely deleted, the „M" (11) symbol in the dis-
play disappears.

10.0 Energy Management 

Approximately 5 minutes after the last key operati-
on, the instrument switches off automatically (auto-
power-off). To switch the instrument on again, turn
the rotary switch from the „OFF" position to the de-
sired function. If the Battery is almost dead, the
symbol (8) appears in the indication. The piece of
equipment works furthermore, however without
claim on retention of the spezifications. If the bat-
tery discharges further, the piece of equipment
switches itselfs off when reaching the minimal bat-
tery tension. At empty battery cannot switch the
piece of equipment on.

11.0 Appropriate Usage 

The instrument may only be used under those con-
ditions and for those purposes for which it was built.
For this reason, in particular the safety references
(chapter 3.0),as well as the technical data including
environmental conditions (chapter 15.0) and the
usage in dry environments must be followed at all
times.

When modifying or changing the instrument,
the operational safety can no longer be gua-
ranteed.

If the battery case is open, the instrument must
not be connected to the measurements circuits

12.0 Maintenance

When using the instrument in compliance with the
instruction manual, no special maintenance is re-
quired.

12.1 Cleaning

If the instrument is dirty after daily usage, it is advi-
sed to clean it by using a damp cloth and a mild hou-
sehold detergent. Prior to cleaning, ensure that the
instrument is switched off and disconnected from
the external voltage supply and any other instru-
ments connected (such as EUT, control instru-
ments, etc.).

Never use acid detergents or dissolvants for
cleaning.
