IMPORTANT: Input channels defined in the Survey Template will override the settings in
the Select Input Channel option once the survey is started. All channels are being data
logged at all times. The active inputs provide real time information on the display and
evaluation for stabilization, hottest TC and coldest TC. In the event that a TC is not
selected, it can be selected when using SDS Reporter for inclusion in the final survey
report.

Analog Inputs
The Super Systems, Inc. 31631 Analog Board contains a group of five channels isolated from the
main DC power source. The board can be connected to thermocouples, voltage sources from
20mV full scale to 1.28 Volts full scale, or 4 – 20 mA current loops. Take caution when using
current loops to avoid damaging the input (see 4 – 20 mA Current Loop connections).
Thermocouple wires can be connected directly to the terminal blocks. The thermocouple
junctions should not be grounded. If they do touch a ground reference, all thermocouples on a
