interface and select [EXT] (external sensor). Since the interface
between the calibrator and the module is digital all the accuracy and
display resolution is derived from the module.

4. Measuring Current

To measure current use the input terminals in the front of the
calibrator. Select the mA function on one of the displays. Current is
measured in mA and percentage of range. The range on the
calibrator is set to 0% at 4 mA and 100% at 20 mA.

Note: The display will indicate "OL" when the measured current
exceeds the nominal range of current measurement (24 milliAmps).

For example:

If the current measured is displayed as 75% then the mA value is 16
mA.
