Figure 6.3. Definitions of measurement ranges in mode Pt100
If the device is equipped with relay outputs, then 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).
Configuration of the device (via menu or RS-485 interface)
does not stop measures
.
6.1.1.
Detection OF THE PEAK VALUES
meter 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 6.4
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 analogue outputs can be controlled depend on the current value of
input signal or the peak value (see
”HOLd” menu
).
