8-9. Peak-to-Peak hold
8-9-1. Operation without block setting
If the HOLD key is pressed or the HOLD signal from the control input/output terminal A7 is set to ON, the TD-260T starts holding
the maximum reading (peak value) and the minimum reading (bottom value) for each sampling. Then, the TD-260T starts holding
and displaying the maximum difference between those two values. If the HOLD key is pressed again or the HOLD signal from the
control input/output terminal A7 is set to OFF, the TD-260T exits the Peak-to-Peak hold mode, and then starts measuring the input
signal again.
If the CLEAR key is pressed or the CLEAR signal from the control input/output terminal A5 is set to ON while the TD-260T is in the
hold mode, the TD-260T resets the peak-to-peak value.
