User manual - METER PDU-4x0-W
If the measurement value does not exceed
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)
does not stop

6.2.
DETECTION OF THE PEAK VALUES
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 displayed and display time counter
will be cleared
(Figure 6.3). If no peaks are detected while time
”timE”
elapses
,
device starts
to show the current value of input signal again. If „
HdiS
”=”
HOLD
” then setting parameter
"timE"
=
0.0
causes holding peak value until
[ESC]
button is pressed.
If „
HdiS
”=”
rEAL
” then
value
"timE"
=
0.0
means no holding. Displaying peak value is signalized by flashing most right
decimal point.
The relays/LEDs and the current output can be controlled depend on the current value of
input signal or the peak value (see
”HOLd” menu
).
