1)
Air vents
Temperature-controlled fan expels air through
these vents to keep the temperature constant
inside the system.
2)
Trigger and remote sensing terminal
block
Connect sensing lines to this terminal to
compensate for voltage drops due to load wire
resistance. This terminal block also contains the
two connections for the remote TTL trigger input
signal.

The numeric keys and rotary knob provide a
convenient interface for setting the operating
mode and desired current/voltage/resistance
levels quickly and precisely. Voltage and current
can be set to a maximum resolution of 1 mV and
0.1 mA respectively (models 8500 and 8502
only). Up to 25 different instrument setups can
be stored and recalled from internal memory.
