Do not clamp on to a conductor when zeroing the jaw's
residual magnetic field until the LCD reads zero.
1. With the clamp jaws empty, turn the clamp meter on by setting the rotary switch to the KW
position (refer to figure 3).
2. Insert the test leads into the input terminals (black lead to COM and red lead to '+').
3. Connect the probe end of the black test lead to the neutral line.
4. Connect the probe end of the red lead to the power line.
5. Clamp the meter onto the conductor where the red test lead is connected.
6. The power clamp will automatically select the appropriate range.
7. Read the Watt (middle of display) and PF (top display) values on the LCD.
8. Press the READ button to scroll through the dual displays of KW + PF, A + V, and KVA + PF.
