1.
Set the selector according to the Settings Table. For DC current, start with the 600 A range.
2.
Refer to “Typical Measurements” for specific measurement instructions.
3.
Test the unit on a known functioning circuit or component.
• If the unit does not function as expected on a known functioning circuit, replace the
battery (or batteries).
• If the unit still does not function as expected, send the unit to Greenlee for repair. Refer to
the instructions under the Warranty.

Take the reading from the circuit or component to be tested.
5.
If it is a DC current reading, remove the clamp from the circuit and press the ZERO button.
Clamp the jaw around the circuit again to measure the actual DC current.
If the resolution is not satisfactory on the 600 A range, remove the meter from the
conductor and switch to the 400 A range. Repeat steps 4 and 5.
