AC AMPS NOTES
1. Specifications apply for sinewave input, AC+DC coupling, 1 power line cycle, digital filter off,
following 55 minute warm-up.
2. Add 0.005% of range uncertainty for current above 0.5A rms for self-heating.
3. Typical values.
4. For DELAY=0, digital filter off, display off, internal trigger. Aperture is reciprocal of line
frequency. These rates are for 60Hz and (50Hz).
5. Actual maximum voltage burden = (maximum voltage burden)

6. In burst mode, display off. Burst mode requires Auto Zero refresh (by changing resolution
or measurement function) once every 24 hours.
