Main Displays and Sub Displays
Each time you press the DISPLAY key of function 1 or 2, the main display switches
between showing the physical value and percentage. When the main display is
showing the physical value, sub display 1 shows the percentage, and vice versa.
Sub display 2 shows the thermoelectromotive force of a thermocouple, the
resistance of an RTD.
Sub display 3 shows the temperature of a reference junction or the amplitude
voltage.
The 0% and 100% values can be shown or hidden using DISPLAY.
