That's me. Check the Excel file properties.
I use it for calibration checking charts when I have the techs install instruments. What is handy is the PLC counts. If you are looking at the raw value in a register just check the chart. Or don't have a MA meter but have a voltmeter to check the loop and it has a 250 ohm resistor check volts in the chart. I carry a pencil type VOM and a 250 ohm resistor for quick checks. I also have a version of the Excel chart running on my pocket PC.
