Clamp-on ammeters operate based on magnetic field induction, not connected electrically to the measured circuits. This instruments can measure and removed without disconnecting the circuits. Thus, the reading on their measurements is affected by some factors outside themselves. This research investigated some external factors those may affect the reading of clamp-on ammeter. The external factors were conductor cross-section, insulating size and material, type of load, metal cubicles and other circuit existences for various current magnitudes. The differences of reading were obtained by comparing the clamp-on ammeter measurement results to those the conventional ammeter. From the external factors, the largest influence was existence of other circuit line that pass by the clamp. The difference of reading had variation , depend on the flowing current. Whereas the had variation, depend on the size of cubicle cover the clamp, where the difference of reading. While the influences of other external factors were relatively low, beow 10%, with the reference on reading of conventional ammeter.
