Increase or decrease the current output by 100, 10 or 1 counts. The resulting change in output voltage is displayed in the upper line.

Continue adjustments until the correct current is measured with the current meter.

EXIT ignores the

new setting, ENTR

accepts the new

setting.

If a current meter is not available, an alternative method for calibrating the current loop outputs is to connect a 250 Ω ± 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:
