range
Current for external display- or evaluation equipment can be supplied directly from the circuit,
when operating a transducer with current output. A voltage drop specific to the display unit is
to be considered. The UHP-display unit of type WUR-1 has a specific voltage drop of 6 V. The
transducers are short-circuit-proof for a short time, but anyhow any incorrect connection of
the instrument should be avoided.
