3.5 Measuring AC AMPS:
Switch the function selector to A~range.
Open the jaws by pressing the handle and insert the
cable to be measured into the jaw.
Close the clamp and note the reading on the LCD.
Note: Never clamp the Jaws around two wires as this
will cause inaccurate readings. Only clamp Jaws
around a single wire — either the HOT or
NEUTRAL WIRE.
Note: When the display is hard to read, push the hold
button to freeze the reading.
