Analysis Tools (Data Simulation)

Post by alb » Sat Apr 28, 2012 3:26 pm

Analysis Tools in v2.3.11157 is a really helpful addition. I'm not sure the Gauge Variables tab is functioning as intended however.

If your gauge is not in native units (defined per the database parameter) it seems to be wrong.

examples:
100°C != 312°F
100kPa != 115psi

Near as I can tell, the arithmetic pulls the desired native value from the Gauge Variable slider bar (X), performs the correct unit conversion, then erroneously adds the native value from the slider bar. ie. Y = X * (conversion factor) + X

Correct form: Y = X * (conversion factor)

See attached screenshot from PV750 MSTD.

In writing this, I believe I figured out how to predict the error and a reliable work-around to test non-native-unit gauges.
