Protection against interference

An MI-900 used for military purposes is protected against radio interference. Thus it complies with the requirements of the MIL-standard 461C, part 8 , method UM03. This calls for providing the voltage and measurement cables with separate interference protection devices. The MI-900 and analog indicators have already been protected.


Use of password

The purpose of having a password for entrance to part of the program is to protect many very vital parameters from being changed by unauthorized or untrained personnel, because this would jeopardize the safe and accurate function of the MI-900.


Software updates

Updating the software is done via the memory card. Manufacturer automatically sends the updates and the updating can be done on site.


PC Software and connectivity

You can connect the MI-900 to a laptop via USB or RS232. The Friction software gives you detailed information about the measurement in clear colors. The data can be transferred in real time or afterwards via the memory card. The data can be stored and printed out.
