• Historical viewer can only display data that has been logged using AddTrigger. The

extension is .mld.

• You can open multiple data files simultaneously. The number of data files that can be

opened simultaneously varies depending on the memory size of the PC and the free disk

space.

• If the file size is large (the number of data points that are logged is greater than or equal

to 8 K and the size is 10 MB or more), the Select Option (file loading condition) dialog box

appears for you to decide how to load the file’s contents.

Select either of the following methods and click Select. The waveforms appear.

• When Read data as need (Minimum Memory) is selected

slower, but the size of the used memory can be minimized.

• When Read all data into memory (Fast Update) is selected

Displays the data by loading all the data into the memory. The amount of used memory is

large, but the display speed is faster.
