File name
The file name is set by the user (using up to 8 half-size letters and
numbers). If the file name is not set by the user, the instrument sets
a file name automatically.
Device to be connected
to the RS-232C
PC/printer
No output to the printer when the interval is less than 1 minute
THD selection
THD-F (based on the fundamental)/THD-R (based on the fundamen-
tal and all harmonics)
Harmonic order for
display
All order/odd order
Sampling method
PLL synchronization/fixed clock (50/60 Hz)
Backlight
Auto OFF/ON/OFF
Auto OFF turns off the backlight automatically 5 minutes after the last
key operation. After the backlight is turned off by Auto OFF, it can be
turned on again by pressing any key (the same applies when the
keys are locked).
Display average times
OFF/2/5/10/20 (moving average of continuous waveform)
