Maximum Input
To be used in protected, low energy circuits only, not to exceed 250 V or 4800
Volt-Amps. (IEC 664 Installation Category II.)
mA 300 mA dc or ac rms. Protected with a 500 mA, 250 V, IEC 127-sheet 1, fast
blow fuse
A 10 A dc or ac rms continuous, or 20 A dc or ac rms for 30 seconds maximum.
Protected with a 15 A, 250 V, 10,000 A interrupt rating, fast blow fuse.
Note
Resistance between the COM binding post and the meter’s internal
measuring circuits is approximately .003
