7.5 Long Lead Lengths

Long lead lengths cause errors in the measured temperature and relative

humidity. The approximate error in temperature and relative humidity is

0.52°C and 0.52% per 100 feet of cable length, respectively.

When long lead lengths are required and the above errors in temperature and

relative humidity are unacceptable, use the HC2S3 or HMP155A temperature

and humidity probe.

Understanding the following details are not required for the general operation

of the HMP60 with Campbell Scientific’s dataloggers. The signal reference

and the power ground (black) are the same lead in the HMP60. When the

HMP60 temperature and relative humidity are measured, both the signal
