Example:
A signal of 5...15 mV corresponds to a weight of 0...1000 kilo.
It must be possible to detect a 50% overrange of the scale on the
analogue output of the mV transmitter at the same time as the display
shows 150%.
The following settings will result in the requested function with an
output signal of 4...19.9 mA:
Input: InL = 5.0, InH = 15.0, InO = 50.0
Output: OL = 4.0, OH = 14.6, UI = 002
Please note that the output span has been set to (14.6 mA - 4.0 mA) =
10.6 mA which, with an addition of 50%, will result in a span of (10.6 +
(10.6 * 50/100)) = 15.9 mA.
3.0 CAL - SETTING OF CALIBRATION VALUES
The calibration function is a relative calibration, i.e. the percentage input value
for the low calibration must be entered in submenu 3.1{CLO - Calibration Low},
and the percentage input value for the high calibration must be entered in
submenu 3.2 {CHI - Calibration High}. The entered percen tages are used for
calculating the actual input span.
When {CHI - Calibration High} is activated, the calculation is made using the
percentages in {CLO} and {CHI}.
3.1 CLO - Setting of low calibration value
Key
2. Enter the calibration value by the 3 and 1 keys.
Connect the low calibration signal to the input. Activate the
3 and 1
keys simultaneously.
3.2 CHI - Setting of high calibration value
Key
2. Enter the calibration value by the 3 and 1 keys.
Connect the high calibration signal to the input. Activate the
3 and 1
keys simultaneously.
The input span is now calcu lated using the entered calibration values.
The mV values are read from the submenus {1.1 - InL and 1.2 - InH}.
4.0 OUt - SETTING OF ANALOGUE OUTPUT
4.1 OL - Low - 0% setting of analogue output
Valid selections are current in the range 0.0...20.0 mA or voltage in the
range 0.0...10.0 VDC.
4.2 OH - High - 100% setting of analogue output
Valid selections are current in the range 0.0...20.0 mA or voltage in the
range 0.0...10.0 VDC.
