User manual - METER SWE-94-U
If the result of measurement exceeds the
permissible measurement range
, warning
”-Hi-”
or
”-Lo-”
is displayed rather than input signal,
depending on exceeded value (see
description of
“Lo r”
and
“Hi r”
parameters, paragraph
”inPt” menu
). The warning can be
effect of measurement circuit malfunction. In that case
“-Lo-”
means shortcut and
“-Hi-”
means break of measurement circuit. If sensor failure will be detected (e.g. broken wires), then
”S.Err”
warning will be displayed.
Figure 6.2. Definitions of measurement ranges in mode 0 ÷ 150mV
If the measurement value do not exceeds
permissible measurement range
but
displayed value exceeds range -999 ÷ 9999, the warning ”
-Ov-
” is displayed rather
than the calculated result.

In the measurement mode user can check main thresholds values. After pressing
[^]
or
[v]
button, name of the threshold (e.g.
”rEL1”
) and his value will be displayed on the display
in alternating mode. If
[^]
or
[v]
will be pressed in 5 sec again, the next threshold will be
displayed, else the device comes back to the measurement mode. If a
free access
is enabled
(see description of
”SECu” menu
), user can change the value of particular threshold pressing
button
[ENTER]
(see:
PARAMETERS EDITION
).
All accessible parameters can be changed by entering the menu (see:
DEVICE
PROGRAMMING
). Use the local keyboard or the remote controller to do it. (Note: all
parameters can be remote changed via RS-485 interface).
