”Lo r”
”Hi r”
“AL”
- this parameter determines the behaviour of analogue output if any critical situation occurs. According to
version of the device, this parameter can be set:
When the critical situation goes, the output signal will be set to value calculated due to formulas given above.
7.3.7. ”bri” parameter
This parameter allows user to set bright of the LED display, bright can be set to conventional values from 1 to
8.
7.3.8. ”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
For active current output:
“noCH”
- current will not change,
“22.1”
- current will be set to 22.1 mA,
“3.4”
- current will be set to 3.4 mA,
“0.0”
- current will be set to 0 mA.
For passive current output:
“noCH”
- 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:
“noCH”

User manual
this parameters define the output value range. If calculated output value
Out
exceeds defined range then
analogue output generates signal equal to upper or lower border of the defined range. These parameters defines
the percentage extension of nominal analogue range (with 0,1% resolution).
Parameter
“Lo r”
defines lower border of the range due to formula:
Out
min
=
A
- (
A
× “
Lo r
” %), where:
A
– lower signal value range limit.
This parameter can be set from 0 to 99.9% (for active current output and active voltage output) or from 0 to
29.9% (for passive current output).
Parameter
“Hi r”
defines higher border of the range due to formula:
Out
max
=
B
+ (
B
× “
Hi r
” %), where:
B
– higher signal value range limit.
This parameter can be set from 0 to 19.9% (for active and passive current
output) or from 0 to 9.9% (for active voltage output).
In example on page
45
of the
DISPLAY VALUES CALCULATION
paragraph the procedure of the analogue outputs
determining is presented in details.
