Operating Speed Notes
1 For display off, 0.01 power line cycles, autorange off,
digital filter off, autozero on, offset compensation off.
Display on may impact time by 3% worst case. To
eliminate this impact, press ENTER (hold) to freeze
display.
2 Using 386/33 computer, average time for 1000 readings,
byte order swapped, display off.
3 For on-scale readings, no trigger delays, display off, 0.01
power line cycles, autorange off, digital filter off, offset
compensation off, autozero off.
4 Ratio and delta functions output one value for each pair
of measurements.
5 Based on 100kHz input frequency.
