4.2 ACA MEASUREMENT
(1) Turn the rotary switch to
range.
(2) Open the clamp jaw and grip one
wire and get the reading directly.
To get the most precise reading, should user put the wire in the
middle of the close jaw (refer to the picture 3).
Note:
1.
Firstly users should select the highest range, if users are
not sure about the range of current under test, and then select the
proper range based on displaying value.
2.
DO NOT input the current higher than the limit, or it
would damage the meter.
4.3
ACV MEASUREMENT
(1)
Turn the function swift to
range.
(2)
Insert the black test lead into “COM”
terminal, and the red one into “V/
Ω
” terminal.
(3)
Connect the test leads into the circuit and get
the measurement value from the LCD. (refer to
picture 4)
(picture 4)
Note:
1. DO NOT input the voltage over the limit, or it would damage
the meter.
2. Be careful while measuring a high voltage circuit. Do not touch
the high voltage circuit.
4.4 DCV MEASUREMENT
(1) Turn the function swift to DCV range.
(2) Insert the black test lead into “COM” terminal, and
the red one into “V/
Ω
” terminal.
(3) Connect test leads to the test point. LCD will display
polarity and voltage of the test point connected by the
red test lead. (refer to picture 5)
Note:
1. DO NOT input the voltage over the limit, or it would damage
the meter.
2. Be careful while measuring a high voltage circuit. Do not touch
the high voltage circuit.
4.5 NCV MEASUREMENT
NCV
Static electricity or other sources of energy
may randomly trigger the sensor. The result is only
for reference.
4.5.1
Turn the rotary switch to NCV position.
4.5.2
Hold the top of the meter very close to the
voltage
source
under
test.
4.5.3 If voltage is present, the NCV LED will flicker rapidly or
intermittently
NOTE:
1.
Even no indication when NCV test, there might still voltage be.
