Saving The Momentary Value; Electrical Features; Mechanical Features - Pepperl+Fuchs KT-LED-24 PT100-24 VDC Mode D'emploi

6.2 Saving the momentary value (Display-Latch)
In case of a High Signal at the Latch input, the current mea-
sured value is frozen on the display. The minimum and ma-
ximum value acquisition continues operating in the
background.
7 Troubleshooting and alarm messages
7.1 Display does not light up
If the display does not light up, check the supply voltage
or the power supply cables. Do not open the housing by
force.
7.2 Measuring rang overflow or underflow
