If the result of measurement exceeds the permissible measurement range , warning
”-
Hi-
”
or
”-Lo-”
is displayed rather than input signal, depends on exceeded value (see
description of
“Lo r”
i
“Hi r”
parameters, paragraph
”inPt” menu
).
Figure 3.2. Definitions of measurement ranges in mode 0 ÷ 20mA
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 ).
Input type, range of displaying values, characteristic of conversion, decimal point
position and measure filtering ratio, are user configurable parameters. 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).
Configuration of the device (via menu or RS 485 interface) do not stops
measures .
6.2. Detection of the peak values
The PD96 controller is equipped with peaks detection function. It can detect a peaks of
the input signal and display their values. Presets connected with this function are placed
in
”HOLd”
menu (see description of
”HOLd” menu
). The detection of the peak can be
done if the measured signal raises and drops of value at least equal to parameter
”PEA”
.
Detected peaks are displayed during the time defined by parameter
”timE”
. If a new
peak will be detected while one is displayed, this new peak will be
