Details of Functions
6.2.1 Peak-hold
The MG80-SC holds the peak values at all times.
The peak values are checked by switching among the output value modes.
The start function makes it possible to restart measurement from an optional position.
6.2.2 Preset
When the reference point is not used
When the preset value recall is supplied, the preset value that has been set is set to the current value.
When the reference point is used
In this case, the function uses the master preset value (refer to section 6.2.3).
When the master value is supplied as the preset value input after the reference point has been loaded for the first
time, the distance from the master value (preset value) to the reference point is calculated, and the reference point
offset value is generated internally and stored.
After the reference point has been loaded for the second and subsequent times, the reference point offset value is
automatically loaded, which means that the preset value need not be input for the second and subsequent times.
