resulting change in output voltage is
displayed in the upper line.
Continue adjustments until the correct

Figure 5-27:
Analog Output – Zero and Span Value Adjustment for Current Outputs
If a current meter is not available, an alternative method for calibrating the current loop outputs is to connect a
250
1% resistor across the current loop output. Using a voltmeter, connected across the resistor, follow the
procedure above but adjust the output to the following values:
