3.4 F100 thermometer inputs
There are two input channels; two 5 pin DIN input-sockets are located at the rear of the instrument.
These are designed to take either PRT or thermistor probes. Channel A is colour-coded red. Channel
B is colour-coded blue.
Figure 3.4 - Rear panel
Either channel can accept either Smart or Passive probes; any combination of probes can be use
together. Smart probes (described in section 6.0) contain their own calibration information and
communicate this to the F100 as soon as they are used. Passive probes do not contain calibration
information and the F100 must be set-up with the calibration information for each probe used (and
each time the probe is changed).
