mA accuracy specifications apply within the following limits, based on reading rate:

Slow Reading Rate:

Between 15,000 and 99,999 counts (full range)

Medium Reading Rate:

Between 1,500 and 30,000 counts (full range)

Fast Reading Rate:

Between 150 and 3,000 counts (full range)

Maximum Crest Factor

3.0

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
