Automatic instrument switch-off Basics of operation
Auto mode
The AUTO mode offers advantages with test objects
having a rough sufrace and with probes showing con-
siderable wear.
The two operating modes are always suitable for nor-
mal applications.
H Note:
The high temperature probe HT 400 must be oper-
ated in the AUTO mode.
Operation:
– The DA3 or AUTO display appears and flashes for 3
seconds.
– Within this time, you can toggle between the two
operating modes using m to select the required
setting.
– Just press a key to continue the operation using the
displayed setting. Otherwise the instrument will take
over the setting after 3 seconds and switch to
stand-by-mode.
– The selected setting is kept and also displayed next
time the instrument is switched on or a probe is
exchanged.
Switching the instrument off
You switch the instrument off by pressing c and keep-
ing it pressed for about 3 seconds.
4.4 Automatic instrument switch-off
The DM4 has an automatic instrument switch-off.
This automatic switch-off activates if the instrument
has not been used after 3 minutes (no key activation,
no coupling or decoupling of the probe, no interface
activity with the DM4 DL).
By doing this, the current consumpution is decreased
and you do not waste any battery operation time.
