MScope

MScope is a very nice application that allows you to manage, store and load up to six inputs. It helps record measurements over a period of up to 24 hours.
It works as an oscilloscope for Metex M36xx, M38xx, M46xx and ME-11 devices.

Easy-to-use interface with plenty of tools at hand

The application sports a rather intuitive graphical interface with plenty of tools at hand and some settings that you could adjust to meet your preferences. It doesn't actually install on your computer, simply double click on the executable file and the application will open.
This is quite nice, since it means that it won't take up that many system resources and you can easily remove it from your computer when you no longer need it.

Perform various measurements on your computer

MScope allows you to open various .msc files and pick from one of the colors available. You can choose from green, red, magenta and more. You can record data over a certain interval of time, the minimum amount is 1 second while the maximum reaches 24 hours.
There's the option to set an alarm if the frequency drops below a certain rate and you can have it draw frequencies when active. Intervals can be changed and it displays information on the current run time and alarms.

More features and tools

You have the option to copy colored diagrams and save the graph or certain frequencies. In addition to that, it displays the frequency at the top of the screen, together with other details in the graph.
You can also change the port and set a certain frequency. The results can all be printed and copied into the Windows clipboard using resource-saving metafile graphics, and thus exported easily to other applications.
In conclusion, MScope is a nifty application that connects to your multimeter to perform measurements over a period of time and uses alarms.
