MinHold
This function holds the minimum value of display value. There are two modes of “NormalHold” and “AreaHold”,
and the mode can be changed by the “HoldMode”.
NormalHold: As long as the external control terminal is set to the L level, the display continues to be updated
with the minimum value. By setting the pin to H level, holding is canceled and the latest
display value is displayed.
AreaHold: As long as the external control terminal is set to the L level, the display continues to be
updated with the minimum value. When the terminal is set to H level, it keeps holding
at the minimum value at that point.
* When the display value becomes -OVER during control of the minimum value holding function, the -OVER
display will not disappear unless control is canceled once.
AmpHold (Peak to peak)
This function holds the difference between maximum and minimum value.
There are two modes of “NormalHold” and “AreaHold”, and the mode can be changed by the “HoldMode”.
NormalHold: As long as the external control terminal is set to the L level, the display continues to be
updated with the peak to peak value. By setting the pin to H level, holding is canceled
and the latest display value is displayed.
AreaHold: As long as the external control terminal is set to the L level, the display continues to be
updated with the peak to peak value. When the terminal is set to H level, it keeps holding
