4.) Switch on the testing wire. Read after clamp meter remains
stable.
5.) When measuring current, to get more accurate readings,
the ambient temperature must be 0 to 40°C.
4.5. AC A MEASUREMENT
(I) Turn the rotary function switch to A position.The meter is
default at DC A measurement after power on. Press SELECT to
switch between AC or DC measurement.
(2) When the meter is used in a strong magnetic field,
the readings could be unstable or inaccurate. Press REL
to clear to zero before measurement.
(3) Press the clamp gunlock to open the clamp
jaw to get testing wire inserted in the middle and
clipped completely. To ensure measurement
accuracy, please check to ensure that the testing
wire is placed in the middle of clamp jaw (fig.6).
NOTE:
(I) Ensure that the testing wire is placed
in the middle of clamp jaw. Otherwise there will be
additional accuracy on the reading.
(2)The max.testing current is 600A. Exceeding
the rated current for long time will damage the meter.
4.6. RESISTANCE MEASUREMENT
(I) Turn the rotaryfunction switch to" "position.
Press SELECT to choose Ω measurement.
(2) Plug the red test lead into "V Ω " terminal
and the black test lead into COM terminal.
(3)Touch the test leads to the test points. Read
measurement values from the LCD (fig.7). Fig.7
NOTE:
(1) When measurement is to be done in manual range,
if user has no idea about the resistance range of testing
object, switch to the highest range.
(2) If "OL" appears on LCD, it means the testing value is over
range. Switch to a higher range. lf the testing resistance is above
1M
Ω , the readings take a few seconds to get stable.
(3) If the input is in open circuit, "OL"appears on LCD.
(4) When measure a live resistor, make sure that
all power sources of the testing circuit are switched off
and all capacitorsare fully discharged before measurement.
(5) If there are large errors during measurement,
it is possible that the measurement values are affected
by other livecomponents or by electric potentials
