The overall probe accuracy is a combination of the thermistor’s interchangeability specification, the accuracy of the
bridge resistor, and error of the Steinhart-Hart equation. The major error component is the interchangeability
specification (tolerance) of the thermistor. The bridge resistor has a 0.1% tolerance with a 10 ppm temperature
coefficient. Effects of cable resistance is discussed in
Long cable lengths (p. 14).
7. Installation
If you are programming your data logger with Short Cut, skip Wiring (p. 10) and Data logger
programming (p. 12). Short Cut does this work for you. See QuickStart (p. 2) for a Short Cut
tutorial. This section discusses the following:
7.1 Placement on a photovoltaic (PV) module 7
7.2 Mounting/cable strain relief 8
7.3 Wiring 10
7.4 Data logger programming 12
7.1 Placement on a photovoltaic (PV)
module
The PV module may or may not have distinctive photocells. If the PV module does not have
distinctive photocells, center the sensor on the back of the PV module. If the module has several
distinctive photocells, center the sensor on the back of the photocell that is the middle of the PV
module.
