PC software only.
There 3 main displays are visible :
 LCD1 – the current or guidance percent preset range display. In accordance with display configuration the
current value in 4 -20 mA current loop, or percent guidance preset range is possible to display.

LCD2 – the measured temperature digital value display; the calibrated temperature value according to
user’s units display; the process variable units or user’s units display; the MENU announcement and other
information or warning announcement display. In the case the digital temperature value or the calibrated
temperature value display, the sign „–„ can be visible before displayed value. The decimal point position is
