Back Up MadgeTech 4 Data

Posted on

This article instructs users to back up data in the MadgeTech 4 Standard or MadgeTech 4 Secure software. The scope of this back up includes but is not limited to the following: datasets and reports stored within the internal file database, user defined preferences and settings, secure user database, security settings, and the audit trail. The scope of this back up excludes any datasets or reports saved outside the internal file database, such as .mtff/.mtffs documents or Excel exports saved in Windows.

The MadgeTech 4 file database is stored locally, and MadgeTech recommends keeping it in the default location. By default, the Preferences Directory is located here:

C:\Users\[WINDOWS_USERNAME_HERE]\AppData\Local\MadgeTech\MadgeTech 4

Note:  The AppData/Application Data folders may be “Hidden”. If the folder is not visible, turn on “View Hidden Files, Folders, and Drives” in Folder Options.  Folder Options can be accessed by searching for it in the start menu search in Windows Vista, 7, 8, 10 or by selecting it from the Tools menu in file explorer in Windows XP.

The location of the user data is determined by the method of the original installation, and whether the user used the default location for the Preferences Directory or moved this folder to a new location. To verify the Preferences Directory folder location, the main user of MadgeTech 4 should open the software, go to File>>Options>>File, and record (but not change) the location shown for Preferences folder.

Once the location of the Preferences Directory has been verified, close the software, then copy this folder and save it to a backup location. Users may want to include this folder in an automatic back up procedure. 

Change Wireless Channel On RFC1000, RFOT (original model), Therm-A-lert data loggers

Posted on

There are dip switches on the RFC1000s, the original larger model RFOTs, and all models of Therm-A-lerts. There are four switches together labeled 1, 2, 3, and 4. These dip switches are what you use to configure the wireless channel that the wireless system operates on. 

For most customers the default (Channel 25) setting—1,2,3 UP and 4 DOWN—should be suitable. However, if you are having signal strength issues or wireless interference, in otherwise good locations you may want to try switching all of your loggers and RFC1000s to a different channel by changing the dip switch configuration. If some of the loggers or RFC1000s are configured with different combinations, they will NOT communicate with each other. This means if you wanted to set up two discrete networks of loggers that were separate from each other, you could simply set up some of them on one channel, and the rest on another.

These switches should not be confused by the wireless On/Off switch, which is a small black switch that can be set to (1) for Wireless mode or (0) for Stand-Alone mode.


When changing the channels, wireless should be toggled off, and toggled back on again after changing the channels. The channel change will not work properly unless this reset is performed.

What is the Operating Environment vs. the Measurement Range?

Posted on

The measurement range of an external sensor, such as a probe, RTD or Thermocouple, can often exceed the operating range of a data logger. A probe, RTD, or Thermocouple may for example have a range of -200 degrees Celsius to 260 degrees Celsius. This only means the probe itself can be subjected to those temperatures.

If the Operating Environment is specified at -40 degrees Celsius to +140 degrees Celsius, then the data logger will fail if operated it beyond that range. Additionally, exposing a battery beyond its operating limits can be extremely dangerous. In order to prevent catastrophic failure, danger to people or property, and damage to the data logger, the data logger in the range specified in the Operating Environment at all times.
