8.1.3 Checking of correct measuring connection
(socketallocation)
The instrument implements an automatic check, corresponding to the measurement
selected, to see if the correct input sockets are used.
The display symbols
and
and are assigned to the corresponding
sockets.
From the way the symbols are displayed, the correctness of the connected wiring can
be concluded by the following features:
•
socket incorrectly wired (or, by mistake, not wired): corresponding symbol
flashes.
•
socket correctly wired: corresponding symbol is steady active
•
socket correctly not wired: corresponding symbol is blank
8.1.4 Safety control measurements
Before each measurement the instrument automatically checks the measuring
conditions and, while simultaneously displaying the kind of error, prevents
measurements from being started under the following conditions:
•
excessive voltage on the sockets (> 24 V in RE und R~; > 3 V in R
...
)
•
wrong or incomplete connection
•
Problems during the measuring sequence ( display " E1 ... E5" ) see display
description chapter 8.
•
Battery voltage too low ( display LO-BAT )
