– 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%.
Non-Contact AC Voltage Measurements
1. Touch the probe tip to the hot conductor or insert into the hot side of the electrical outlet.
2. If AC voltage is present, the back light will flash a bright red.
3. The auto off feature will turn the meter off after 15 minutes
，
The NCV function keeps
on working when test the AC Voltage .and Set the function switch to the
OFF
position,
The NCV function can not work.
NOTE
: The conductors in electrical cord sets are often twisted. For best results, rub the probe
tip along a length of the cord to assure placing the tip in close proximity to the live
conductor.
NOTE
: The detector is designed with high sensitivity. Static electricity or other sources of
energy may randomly trip the sensor. This is normal operation
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 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 Autoranging, press and hold the
RANGE
key for 2 seconds.
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 will display and hold the maximum reading and will update only
when a new “max” occurs.
2.
Press the
MAX/MIN
key again and the display icon "
MIN
" will appear. The meter will
display and hold the minimum reading and will update only when a new “min” occurs.
3.
To exit MAX/MIN mode press and hold the
MAX/MIN
key for 2 seconds.
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.
WARNING:
Risk of Electrocution. Before use, always test
the Voltage Detector on a known live circuit to verify proper
operation
