Overload protection: 0.5A/250V, 10A/250V fuse.
[1] All ac ranges are specified from 1 % to 100 % of range. Below 5 % of range, add10 counts.
Because inputs below 1 % of range are not specified, it is normal for this and other true-rms
meters to display nonzero readings when the test leads are disconnected from a circuit or are
shorted together. For volts and amps, crest factor of ≤3 at 3000 counts, decreasing linearly to 2 at
full scale. AC volts and AC amps are dc-coupled.
