a) Current
Measuring alternating current to 80 A (AC)
Measuring direct current to 80 A (DC)
1. Use the mode switch (4) to select the desired measurement range. If you are not sure of the
appropriate range, first select the 80 A range and switch to 4 A if necessary.
2. Open the current clamp (1) by the opening lever (3).
3. Place the clamp around the conductor under test and release the opening lever (3). Make sure
that the conductor is not jammed. The conductor must move freely inside the current clamp
sensor's (1) round opening.
Place the clamp around one conductor at a time. If the clamp is in contact with more than
one conductor simultaneously, the currents will cancel each other out and you will receive no
reading.
4. The reading is shown on the LC display (10).
