nmScale PLC to field convertor

nmScale is used to convert a certain value in a range to its correlating value in another range.
This comes handy for instrumentation control and PLC technicians who want to calibrate or troubleshoot the instruments at the field by matching the value read from the sensors with the readings at the PLC I/Os.
For example a value of 8mA from an analog device with a range of 4-20mA can be converted to its correlating value of 4095.75 in the range of 0-16383 (that is the range scaled for PID).
You can select the preset values for ranges from a drop down list, but you are not limited to those ranges and you can type your own different ranges manually. You can even use this app to convert the pump speed in frequencies for example 24-60 Hz to its speed in RPM for example 1500-3600 RPM, and simultaneously see the percentage of the value in the range.
Basically you type your minimum and maximum for both ranges and then you type any value in one of those ranges and touch the proper button to convert that value to its correlating value in the other range. You will also see the percentage of the current value in its given range (min to max).
nmScale requires Android 4.1.2 or higher. Please make sure your device meets this requirement.

Please send your comments about the app and how I can make it better for your use to NM’s email that is NaderMaram at GMAIL. Thank you.
