User manual - FLOW METER SPI-638
For passive current output:
“noCHAn”
- current will not change,
“22.1”
- current will be set to 22.1 mA,
“3.4”
- current will be set to 3.4 mA,
For active voltage output:
“noCHAn”
- voltage will not change,
“11.0”
- voltage will be set to 11 V,
“5.5”
- voltage will be set to 5.5 V,
“1.2”
- voltage will be set to 1.2 V.
“0.6”
- voltage will be set to 0.6 V,
“0.0”
- voltage will be set to 0 V.
When the critical situation goes, the output signal will be set to value calculated due to
formulas given above.
If parameter
“OUtmod”
is set to
“oFF”
,
“4-20”
,
“0-20”
,
“0-5”
,
“1-5”
,
“0-10”
or
“2-10”
the “critical situation” means that
permissible measurement range
is exceeded.
If parameter
“OUtmod”
is set to
“modbuS”
, the “critical situation” means
communication delay (when no data is received) longer than
“mbtimE”
parameter (see
description:
“rS-485” menu
).
Before turning off the device it is recommended to first disable the current output's
power supply, and then the device itself. If the current output is supplied while the
device itself is turned off, the output current will be about 27.5 mA.
7.3.11.
”briGHt”
parameter
This parameter allows user to set bright of the LED display, bright can be set to
conventional values from 1 to 8.
7.3.12.
”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 6.2)
“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.
