To save sample data from the Multimeter window during sampling
configured with the [Multiple] tab
(1) Perform steps (1) and (2) of the procedure under “To view real-time sample data during
sampling configured with the [Multiple] tab” on page 7-3.
(2) When you want to store sample data, tap the [Store] button on the Multimeter window.
• This causes the count value on the window to change from 0 to 1. A matrix variable
with the name “MultMat” is created in the [EConSamp] folder, and current sample
data value is stored there.
(3) You can tap the [Store] button whenever you want to store the current data value.
• Each tap of the [Store] button increases the count value by one.
• Saved samples are stored in the “MultMat” matrix variable as shown below.

The shaded parts of the above table shows the data assigned to the variables. The
count values and channel name are not stored.
•
If you do not have four channels selected for sampling, data is not saved for the
unused channel(s). Data is saved in columns only for the channels being used for
sampling, and blank columns are not included in the matrix for the unused
channel(s). The example below shows how data is stored when only CH1 and CH3
are used for sampling.

• Tapping the [Reset] button on the Multimeter window resets the count value to zero
and deletes EConSamp\MultMat. After that, you can store another set of data by
returning to step (2), above.
(4) To close the Multimeter window, tap [Cancel].
• If you want to retain the sample data stored in the “MultMat” matrix variable, use the
ClassPad Variable Manager to save it under a different name. For details, see the
section about the Variable Manager in the ClassPad 300/ClassPad 300 PLUS User’s
Guide.
Tip
• The Multimeter window count is reset to zero by either of the following.
•
When the Multimeter window is displayed by tapping

•
Tapping the [Reset] button on the Multimeter window
•
When ClassPad Variable Manager was used to delete “MultMat” or “MultList” variable from the
[EConSamp] folder, or by changing “MultMat” or “MultList” to a different variable type.
