Use Personal Daq’s screw terminals to connect channel inputs. The terminal blocks are
detachable for ease in making connections. Device labels identify input types and channel
numbers. Each Analog Input channel can be configured for single-ended or differential
volts, or for differential thermocouple inputs. The non-analog channels are designated as
Frequency/Pulse Input (F) and Digital I/O (D).
For Personal Daq, thermocouples are to be connected in differential mode only. This is
because single-ended connections can result in noise and false readings. In regard to
Differential connection, the red wire connects to the channel’s Low (L) connector; and
the second color-coded wire connects to the channel’s High (H) connector. The user’s
manual contains additional information.
