PF Illuminates when the LCD displays shows the measured
power factor. It also illuminates in the calibration mode of
operation. In calibration mode, the PF LED is always lit in
combination with the measurement or output junction being
calibrated. In normal mode of operation, only one LED in
this group is on at a time. See Note.
Note: For peak current, power and power factor measurements, Option -OP1 is required. If
this option is not installed, these functions are not available and the SELECT button will only
toggle between FREQ and CURR modes.
