Click the item Reset settings to use the default calibration settings.
E.3 Output 4-20 mA
1. Connect an auxiliary voltage source, a measuring
device of resolution 0.001 V and a reference
resistance box of accuracy class at least 0.05 to the
output (Fig. E.4).
2. Ensure the supply voltage is within the range 15…28
V.
3. Set the reference resistance box to 500 ohm.
4. Connect the device to the PC.
5. Switch on the device power supply.
6. Start ALP and select the menu item Device >
Calibration to start the calibration tool.
7. Select the device model in the open dialog window.
8. Select Analog outputs as calibration target (Fig. E.2).
9. Calculate the output current from the measured output
voltage and the set resistance; enter the result in the
input field (Fig. E.5).
10. Click Next to continue and follow the instructions.
