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, 250V, IEC 127-sheet 1, fast
	blow fuse

A10 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 Ω .
