Programmable Signal Converter - GE Druck TRX-II User Manual

PROGRAMMABLE SIGNAL CONVERTER

With this unique feature any measure signal can be converted into
any on the TRX-II available source signals with full galvanic isolation.
Zero and span settings for both measure and source are fully
programmable.

EXE to open the set-up screen for filling out the measure and source
span. Press EXE again to proceed to the signal converter working
screen. Actual measure and source signals are now displayed.
Note: The signal converter function cannot be used in pulse counting
modes.
