Detecting an open circuit in a 4-20mA loop using the PLC Tools SIM-ALP2

Another great new feature of our SIM-ALP2 is the ability to detect an open wire.  While its original intention was to reduce calls from customers who were trying to measure the simulated signal with a voltmeter that had a blown fuse, it has turned out to be a very valuable troubleshooting feature in the field.
