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 = A - (A × "Lo r" %), where:
min
"Lo r"
A – lower signal value range limit.
"Hi r"
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 = B + (B × "Hi r" %), where:
max
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.
- this parameter determines the behaviour of analogue output if any critical situation occurs. According to
version of the device, this parameter can be set:
For active current output:
"noCH" - current will not change,
"22.1" - current will be set to 22.1 mA,
"3.4"
"0.0"
For passive current output:
"noCH" - current will not change,
"AL"
"22.1" - current will be set to 22.1 mA,
"3.4"
For active voltage output:
"noCH" - voltage will not change,
"11.0" - voltage will be set to 11 V,
"5.5"
"1.2"
"0.6"
"0.0"
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
- current will be set to 3.4 mA,
- current will be set to 0 mA.
- current will be set to 3.4 mA,
- voltage will be set to 5.5 V,
- voltage will be set to 1.2 V.
- voltage will be set to 0.6 V,
- voltage will be set to 0 V.
