Added (Untested) ES51986 and ES51960 support (APPA 71/73 and Amprobe 34XR-A)
Just tested it, it does work for the APPA 71, mostly

Here are a few bugs i found while using it with my APPA 71
OS = Windows 7 x64
Values out by a factor of 10Detail...
All values displayed in the app are out by a factor of 10.
for example 5.167V on DMM is showing as 51.67V
RAW signal = 30-35-31-36-36-3B-38-30-3A-0A
Happens on other things too, ACV, Ohms, capacitance etc.
Continuity range showing kVDetail...
With the DMM on continuity/diode mode, and with the probes open, the digital display shows ~2.4 kilovolts. hehe, thats a lot of volts
RAW = 30-32-34-31-32-31-39-30-30-0A
With probes shorted it shows zero.
Sometimes the app will refuse to close.Detail...
I couldn't see any pattern to why it occurs but sometimes when i click the window close [X] the app prompts to save, I click "no" but it doesn't close.
It continues to run, and ignores repeated attempts to close and must be killed in task manager.
Other times it closes fine.
App will crash if you try use it without any multimeter device configuredDetail..
If you run the app with no meters configured then click meters/connect and gauges/add/digital it will throw a Unhanded exception.
"InvaidArgument=Value of "0" is not valid for 'index'
Parameter named index.
Here is the detail for the exception
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
