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) × (I
MEASURED/IFULL SCALE).
6. In burst mode, display off. Burst mode requires Auto Zero refresh (by changing resolution
or measurement function) once every 24 hours.
TEMPERATURE NOTES
1. Typical speeds for Auto Zero on. For DELAY=0, digital filter off, display off, internal
trigger. Rates are for 60Hz and (50Hz).
