6.2. DETECTION OF THE PEAK VALUES
The SPI-73 flow 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 6.2). 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 can be controlled depend on the current value of input signal or the
peak value (see ”HOLd” menu ).
