HF
supplies the instantaneous real-power information. The
output is a periodic pulse output, with its period
proportional to the measured active (real) power, and to
the HF
states. This output is the preferred output for calibration
due to faster output frequencies, giving smaller
calibration times. Since this output gives instantaneous
active (real) power, the 2ω ripple on the output should
be noted. However, the average period will show
minimal drift.

F
device that supply the average real-power information.
The outputs are periodic pulse outputs, with its period
proportional to the measured active (real) power, and to
the F
states. These pins include high-output drive capability
for direct use of electromechanical counters and
2-phase stepper motors. Since this output supplies
average active (real) power, any 2ω ripple on the output
pulse period is minimal.
