DC Lights up when using the DC rectifier.
AC Lights up when using the AC rectifier.
FND Lights up when using the FND rectifier.
LEVEL
Lights up when the instrument is displaying a harmonic compo-
nent level (harmonic voltage RMS value, harmonic current RMS
value, or harmonic active power).
HD%
Lights up when the instrument is displaying a harmonic content
percentage (harmonic voltage content percentage, harmonic
current content percentage, or harmonic active power content
percentage).
AUTO
Indicates the integration operating mode.
AUTO lamp on: Auto-range integration mode
AUTO lamp off: Fixed-range integration mode
RUN
Indicates the status of integration based on START/STOP key
operation or communications.
RUN lamp on: Integration active
RUN lamp flashing: Integration stopped
RUN lamp off: Integration reset
RUN
EXT
Indicates the status of integration based on external control.
RUN lamp on, EXT lamp on: Integration active
RUN lamp flashing, EXT lamp on: Integration stopped
RUN lamp off, EXT lamp off: Integration reset
HOLD
When the HOLD, MAX, and MIN lamps are all off, pressing the
SHIFT key and then causes the instrument to enter the dis-
play hold state and the HOLD lamp to light up.
To cancel display hold: Pressing once more causes the
display hold state to be canceled and the HOLD lamp to be
turned off.
MAX
When the HOLD, MAX, and MIN lamps are all off, pressing
and then causes the maximum value to be held and the
MAX lamp to light up.
MIN
Pressing while the MAX lamp is lit up (indicating that the
maximum value is being held) causes the minimum value to be
held and the MIN lamp to light up.
Pressing while the MIN lamp is lit up (indicating that the
minimum value is being held) causes the minimum value hold to
be canceled, returning to the normal measured value display.
