Page 21: Internal Scaling
4.3.1 Internal Scaling Use internal scaling if you do not have an actual input signal to the meter. With internal scaling the input values are assumed to be the low and high signal input based on the selection input (e.g. if you selected 4-20 mA input, the “rd1” input value will be 0400 for 4 mA and “rd2”... -
Page 22: Live Scaling
4.3.2 Live Scaling Use live scaling when a stable input source is available (e.g. 4-20 mA or voltage calibrator). Also use live scaling when the actual input from your sensor can be set to output values close to the low and high ends of your input. -
