Radio Shack DMM Script

[ESSCHENK]

Michael,

Great Thank you very Much


Ed

[Michael McSharry]

I should have fixed the display for you in V1.0.0.1.

Hello Michael,

I have the same time issue as with the Webcontrol
It use only am/pm and no 24 Hour format
Maybe you can fix that


Thanks
Ed

Hello Mitch,

Sorry for the delay I was a little bit sick the past few days
The problem was a weak batt in the DVM.
Now your script is working well.

@ Michael
Thanks for your Xap program is have installed the program and its working great.
Now I can use the Dvm all over in the Network.

Thanks you all

Ed

I saw where Mitch's idea could have a variety of applications where one desires to measure instrumented behavior over time. I took advantage of the digit lookup logic within the script and decoded the remainder of the status bits from the DMM to provide a more generalized software interface to this DMM. It is wrapped in HTTP and xAP logic to provide an interactive UI and generalized telemetry of what the DMM is reporting. Mitch's script will likely satisfy the needs of a typical Homeser user who wants to only measure AC voltage. If ones wants to use the DMM in other ways then xapmcsMultimeter http://board.homeseer.com/showthread.php?t=140505 provides that option.

What you are seeing is the output which results if an error is read. The script is written assuming that the meter is set to AC Volts and the scale is set to Volts. If you have something else set, you will need to change the script accordingly. Make sure that your setting match, try again. If you still get the error, please post the results.

Dank u wel,

Mitch

Hello Mitch,

The meter is working good with the original software on the same port
I have switch the port temperary to com1
Because the original software is working not higher then com4


I have some info in the log file

But its not like the output what i want
Also whit HyperTerminal I see some output.

Any idee?

Thanks

Hello,

I have got mine from ebay
http://cgi.ebay.com/ws/eBayISAPI.dll...E:B:EF:US:1120

Ed

So did I... Thanks for the link... I seached there earlier, and didn't find anything.

Any suggestions where to pick one of these up from? I can't seem to find it at the shack any more.

Are there features of the DMM that are being used to capture voltage spikes? For general monitoring of voltages couldn't a 1-wire (or other) A/D be used with an appropriate voltage divider?

Of course that is a way to go, Michael. The DMM was cheaper to buy than developing a safe circuit to interface to 1-Wire.

Hello,

I bought this DVM and want to use your script.
I have placed the files in the script directory
Made 3 Virtual devices
But get no data.

Question
Must the multimeter.startup.txt not put in the startup.txt file!!
I have done that but stil no data
I use Com14
With the software deliverd with the DVM this is working

Any idea whats wrong

Thanks

Ed

Hi Ed,

Yes, the MultimeterStartup.txt script should be called from your startup.txt script to set up the com port. If the virtual devices are not being updated, make sure that your com port is properly working. Shut down HS and open Hyperterm for that com port and see if data is coming through.

Is it possible that the DMM is not set to transmit data through it's serial port?

Also, is the file MultimeterLog.txt in your Logs folder being updated?

Hello,

Yes i like to monitor the up and down voltage from mains
So i want to use the script.
so that i can see in the log file when the Voltage is under a certain level

Most DMMs allow the capturing of min & max voltage readings. I think it's great that Midon came up with a way to capture that data programmatically.
