Warning
To avoid electrical shock and injury:
• Remove Test Leads before making current measurements.
• Do not hold the Meter anywhere beyond the tactile barrier.
• Do not use the Meter to measure currents above the maximum rated
frequency (400Hz). Circulating currents may cause the magnetic circuits
of the Jaws reach hazardous excessive temperatures.
To measure AC or DC current:
1. Turn the rotary function switch to
or .
2. Press SELECT button to choose measurement function (AC A, DC A,
DC+AC A, or Hz). The display reflects the chosen function mode.
3. Open the clamp by pressing the jaw release and insert the conductor to
be measured into the clamp. Ensure the jaws are firmly closed.
4. Close the clamp and center the conductor using the jaw alignment
marks.
5. View the current reading on the display.
6. When measuring AC or AC + DC current, press SELECT button to view
