% 4 – 20mA MEASUREMENTS
1.
Set up and connect as described for DC mA measurements.
2.
Set the rotary function switch to the 4-20mA% position.
3.
The meter will display loop current as a % with 0mA=-25%, 4mA=0%, 20mA=100%, and
24mA=125%.
AUTORANGING/MANUAL RANGE SELECTION
When the meter is first turned on, it automatically goes into AutoRanging. This automatically selects
the best range for the measurements being made and is generally the best mode for most
measurements. For measurement situations requiring that a range be manually selected, perform

displaymeter will display and hold the minimum reading and will update only when a new "min"
occurs.
2.
To exit MAX/MIN mode press EXIT
RELATIVE MODE
The relative measurement feature allows you to make measurements relative to a stored reference
value. A reference voltage, current, etc. can be stored and measurements made in comparison to
that value. The displayed value is the difference between the reference value and the measured
value.
1.
Perform the measurement as described in the operating instructions.
2.
Press the REL button to store the reading in the display and the "▲" indicator will appear on
the display.
3.
The Right auxiliary display displays the initial reading (the stored value)
4.
The Left auxiliary display displays the actual currently measured value.
5.
Main display displays the Relative value (currently measured value minus the stored value).
