8.1 Hardware
To troubleshoot refractometer hardware problems, it is often important to localize
the different cards inside the DTR. The Diagnostic LEDs on the cards help solve the
problems and give an indication on whether a connection is good.
Warning! Hazardous voltage, contact may cause electric shock or burn. Beware of
the live wires in the lower right-hand corner of the H1 interface card.
