“
Lo C
”, “
Hi C
” - these parameters define measurement range of the bargraph. The percentage
value showed by the bargraph is calculated due to measured value (and showed
on digital display).
“Lo C”
parameter defines the value appropriate to 0% on the
bargraph.
“Hi C”
parameter defines the value appropriate to 100% on the
bargraph. Measurements between
“Lo C”
and
“Hi C”
are recalculated due to
formula:
P
=
W
−
"Lo C"
"Hi C"
−
"Lo C"
×
100
%
where:
„P”
denotes percentage value showed by the bargraph,
„W”
- denotes value showed on digital display (the measurement value)
Value of
“Lo C”
can be greater than value if
“Hi C”
. In this case the conversion
characteristic of the bargraph is upturned (it means that when measurement value
raises then the bargraph value falls, and when measurement value falls the
bargraph value raises).
7.3.6.
”bri”
parameter
This parameter allows user to set bright of the LED display, bright can be set to
conventional values from 1 to 8.
7.3.7.
”HOLd” menu
This menu contains parameters connected with peak detection function. See also full
description of the peak detection function in paragraph:
DETECTION OF THE PEAK VALUES
“modE”
- the type of detected changes of the input signal, can be set to values:
”norm”
- peaks
, peak and next drop of the input signal of value equal at least
“PEA”
,
”inv”
- drops, drop and next peak of the input signal of value equal at least
“PEA”
,
“PEA”
- minimal detected signal change classified as peak or drop (see Figure 6.3)
“timE”
- maximum time of displaying of the peak (drop) value, can be set from 0.0 to 19.9
sec, with 0.1 sec. resolution. 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.
“HdiS”
- type of displayed values:
”rEAL”
- current value is displayed,
”HOLd”
- peak (drop) value is displayed,
“H r1” ÷ “H r4”
- relay/LED outputs ( R1÷R4) operation mode:
”rEAL”
- relay/LED operates depend on the current value,
”HOLd”
- relay/LED operates depend on the peak (drop) value.
