AC/DC Current Measurements
Current (A) + Frequency (Hz) Dual Display
WARNING
: Make sure that test leads are disconnected from the meter during current
measurements.
1.
Set the rotary switch to the Amps position (A).
2. Push and hold the DCA/DCW ZERO button to zero the
reading.
3. Press the trigger to open the jaw and fully enclose the
conductor to be measured. The Jaws must be completely
closed to make a measurement.
4.
Read the current/frequency values on the LCD.
NOTE:
The sensitivity for current/frequency
measurement is 5A, and the frequency range is 10 -
400Hz. If the frequency is < 10 Hz, the LCD will display 0
Hz. If the frequency is > 400 Hz, LCD will display "OL".
Voltage (V) and Current (A) Dual Display
Follow the instructions in the section entitled "3

2W Power (W) and Power Factor (PF) measurements
1.
Apply power to the meter with the jaws
clear of any conductors.
2.
Set the rotary switch to the Watts
function (KW).
3.
If the watt reading is not zero, press the
DCA/DCW ZERO button once to zero it.
4.
Insert the test leads into the input
terminals.
5.
Connect the COM (black) terminal to the
neutral line.
6.
Connect the V (red) terminal to the power
line.
7.
Clamp on to the line where the V (red)
terminal is connected. The power clamp will automatically select the proper
measurement range. Read the Watt and PF (Power Factor) values displayed on
the LCD.
NOTE: The "+" sign printed on jaw must face the power source for accurate
measurements.
