WARNING :
Do not clamp on to any conductor when turning on the power of
power clamp. Because the power clamp will auto zero the
residual magnet remained in the jaws at the moment the power
clamp is tumed on. If users clamp on to conductor with current
flowing through, the reading measured later will be inaccurate.
3.1.1. Turn the power on without jaws damping on to any
wire.
3.1.2. Set the rotary switch at W (refer to figure 2).
3.1.3. If the watt reading is not zero. press the DCA/DCW
ZERO button once to zero the watt reading
3.1.4. Insert the test leads into the inpul jack.
3.1.5. Connect the test prod of COM (black) terminal to the
neutral line.
3.1.6. Connect the test prod of V (red) terminal to the power
line.
3.1.7. Clamp on to the line where V (red) terminal is
connected.
3.1.8. The power clamp with automatically select proper
range.
3.1.9. Read the Watt and PF values displayed in LCD.
NOTE :
The "+" sign printed on jaw must face the power source for
accurate measurement.
WARNING : Maximum input for DC V is 1000, and for AC V is
750. Do not attempt to take any voltage measurement that
exceeds the limits. Exceeding the limits could cause electrical
shock and damage to the clamp meter.
a. Set the rotary switch at V (refer to figure 3).
b. Insert the test leads into the input jack.
c. Connect the test prods of the test leads in PARALLEL to
the circuit to be measured.
d. The power clamp will automatically select proper range.
e. Read the voltage and Frequency values displayed on the
LCD.
NOTE :
The sensitivity for voltage frequency measurement is 1V. and
the frequency range is 10 - 400Hz. If the frequency is < 10 Hz,
LCD will show 0 Hz. If the frequency is > 400 Hz, LCD will show
OL.
3.2.2. V + A Dual Display
Follow Ihe instruction in section 3.6.3 3f AC+DC Balanced
Power Measurement V + A. Then users can monitor V and A
at the same time from LCD.
