FIGURE 3-1. The CS205 mounts on the mounting stake with the CS505
3. INSTALLATION AND WIRING
Insert a 107 temperature probe into the CS205
Fuel Moisture Stick. The CS205 installs in the
white compression fitting on the 10974 Fuel
Moisture/Temperature Mounting Stake.
Loosen the compression fitting so that the
CS205 can be inserted. The CS205 inserts
into the compression fitting so that compression
is applied to the split end of the stick gripping
the 107 probe.
Connections to the datalogger for the 107 are
shown in Figure 1-1. The probe is measured by
a single-ended analog input channel. The red
lead is connected to either a HI or LO input.
The black lead connects to any excitation
channel.
Please refer to the 107 probe manual for a
complete discussion of the 107 probe.
4. PROGRAMMING
Instruction 11 is used to measure temperature.
Instruction 11 provides AC excitation, makes a
single ended voltage measurement, and calcu-
lates temperature with a fifth order polynomial.
A multiplier of 1.0 and an offset of 0.0 yields
temperature in Celsius. For Fahrenheit, use a
multiplier of 1.8 and an offset of 32.
