F.5.6 Analog Input Configuration
Some analog inputs are multi-purpose capable and have several configuration options. These inputs are
configured by the GDU (refer to Appendix H.4.19
for GDU 37X systems and to Section 30.4.32 for
GDU 4XX systems) and are capable of reading any voltage up to 40 Vdc.
NOTE
If installing an ungrounded thermocouple to an Analog In input, a DC reference must be
added to the LO input. This can be accomplished by adding a resistance of 1 MΩ or less
between ground and the Analog In LO input the ungrounded thermocouple is installed on.
