Operating Instructions
NOTE
: Ensure that the jaws are clear of any conductors before applying power to the
meter. The meter performs an auto zero upon power-up to null any residual magnetism.
If this is done with a conductor inside the jaw area, the auto zero function will cause
subsequent measurements to be inaccurate.
AC/DC Voltage Measurements
Voltage (V) and Frequency (Hz) Dual Display
WARNING: Maximum input voltages: 1000VDC and
750VAC. Do not attempt to measure voltage that
exceeds these limits.
1.
Set the rotary switch to the Voltage position (V).
2.
Insert the test leads into the input terminals.
3.
Connect the test leads in PARALLEL with the circuit to be
measured.
4.
The power clamp will automatically select the proper range.
5.
Read the voltage and Frequency values displayed on the LCD.
NOTE:
The sensitivity for voltage/frequency measurements is 1V, and the
frequency range is 10 - 400Hz. If the frequency is < 10 Hz, the LCD will
indicate 0 Hz. If the frequency is > 400 Hz, LCD will show OL.
Voltage(V) / Current (A) Dual Display
Follow the instructions in the section entitled "3
φ
Balanced Power Measurements" to
monitor V and A simultaneously.
