HIOKI
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)
Medium for copying
screen
Printer/internal memory/PC card
Beep sound
ON/OFF
Language
Japanese/English
ID No.
1 to 999
Clock setting
Year (4 digits)/month/day/hour/minute (24-hour clock)
