The testo 252 measuring instrument has two
parallel analogue outputs. Depending on the
probes plugged-in, different signals are given out
at the analogue outputs. The value in the top line of
the display is always the output from the top
analogue output.
In order to connect the analogue output, please
use the connecting lead 0409.0084 listed in the
ordering data.
