The WGA-680A detects the difference (amplitude), between the peak value and bottom value, and displays the
peak-to-peak value of the difference.
Key operation
The detecting interval starts when the HOLD key is pressed and after the lapse of delay time.
When the HOLD key is pressed for the second time, the detecting interval ends. The WGA-680A displays
values as normal.
Control input
The detecting interval starts when the HOLD command is ON and after the lapse of delay time.
When the HOLD key is turned OFF, the detecting interval ends. The WGA-680A displays values as
normal.
NOTE
When the display mode is "Hold display mode", the WGA-680A constantly displays the latest measured
value, because there is no holding interval.
When the comparison mode is "Hold comparison mode", the WGA-680A constantly compares the latest
measured value, because there is no holding interval.
The WGA-680A works as follow during detecting interval by turning ON/OFF the "HOLD command"
and "RESET command."
