* The accuracy statement includes the uncertainty of the factory calibration with an enhancement factor k=2 (2-
times standard deviation).
The accuracy was calculated in accordance with EA-4/02 and with regard to GUM (Guide to the Expression of
Uncertainty in Measurement).
7. Installation
If you are programming your data logger with Short Cut, skip Wiring to data logger (p. 7) and
Data logger programming (p. 7). Short Cut does this work for you. See QuickStart (p. 2) for a
Short Cut tutorial.
7.1 Wiring to data logger
Connections to Campbell Scientific data loggers for measuring humidity and temperature using
two single-ended analog inputs are given in Table 7-1 (p. 7). See Long cable lengths (p. 12) for a
discussion on errors caused by long cable lengths.
Table 7-1: Wire color, function, and data logger connection for single-ended measurement
Wire color Wire function Data logger connection terminal
Yellow Temperature signal Uconfigured for single-ended analog input1,
SE (single-ended, analog-voltage input)
Blue Relative humidity signal Uconfigured for single-ended analog input,
SE
Black Signal reference ⏚(analog ground)
Clear Shield ⏚
Red Power 12V or SW12V
1Uterminals are automatically configured by the measurement instruction.
7.2 Data logger programming
Short Cut is the best source for up-to-date programming code for Campbell Scientific data
loggers. If your data acquisition requirements are simple, you can probably create and maintain a
data logger program exclusively with Short Cut. If your data acquisition needs are more complex,
the files that Short Cut creates are a great source for programming code to start a new program
or add to an existing custom program.
