The latest version of Actuel (Version 1.9) for the 9103 USB Picoammeter is now available. This version includes some exciting new features.

Avoid USB Conflicts with other Devices by Selecting a Specific COM Port

You can now select the COM port of the 9103 an instance of Actuel is communicating with. Previously, Actuel would automatically connect to the next available port, which could sometimes cause conflicts with other devices using the same USB chipset from FTDI.

To use this feature, connect and turn on your 9103, and find the COM port assigned in Windows Device Manager:

Next, click the Settings button from main Actuel window, click the “Select COM Port” checkbox, and choose the appropriate port.

Note that this works for multiple instances of Actuel, whereby you can select the 9103 COM port to connect to for each instance. However, you cannot mix automatic and manual selection, and you’ll need to select the appropriate ports any time you run Actuel (since it only recalls the last used port).

Customize Actuel’s Graph Colors

You can now customize the Actuel graph by choosing colors for the axes, data line, grid, and text. You can also turn the grid display on/off.

To change the graph options, click the “Show Options” button in the Data window, and the “More Options” button near the lower-right. Your settings are saved between instances of Actuel, and you can easily reset the colors to their default.

More Improvements…

The latest version has some enhancements to the layout of the Data Window. In addition, it is now possible to Copy or Save data while sampling.
