– 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 Auto Ranging. 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 the following:
1.
Press the
RANGE
key. The “
AUTO”
display indicator will turn off.
2.
Press the
RANGE
key to step through the available ranges until you select the range you
want.
3.
To exit the Manual Ranging mode and return to Auto ranging, press
EXIT
Note:
Manual ranging does not apply for the Temperature functions.
MAX/MIN
1.
Press the
MAX/MIN
key to activate the MAX/MIN recording mode. The display icon "
MAX
"
will appear. The meter left auxiliary display will display and hold the maximum reading and
will update only when a new “max” occurs. The display icon "
MIN
" will appear. The right
auxiliary display meter 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.
Note:
Relative mode does not operate in the 4-20mA function.
1.
Perform the measurement as described in the operating instructions.
2.
Press the
REL
button to store the reading in the display and the "
REL
" indicator will
appear on the display.
3.
Left auxiliary display will display the margin of initial value and the current value.
Right auxiliary display will display the initial reading. Main display the reading after
REL TEST.
4.
Press the
EXIT
button to exit the relative mode.
