User manual for meter with U/I input SRP-77
using
[^]
and
[v]
buttons.
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

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.
The relays/LEDs can be controlled depend on the current value of input signal or the
peak value (see
”HOLd” menu
).

CONTROL OF THE RELAY OUTPUTS
The control of the object (measured signal) is realized via relay outputs. Front panel
LEDs named „
R
” indicates the state of particular relay output.
