PS200/CH200 12 V Charging Regulators
See Appendix A.4.1, Zero Out QLoss SDI12 Programming Example, for an
example program.

Below is a CR1000 programming example that acquires all 9 measurements
once per minute from a PS200/CH200. Note that the PS200/CH200 does
internal averaging of the voltage, current, and temperature measurements, with
an averaging period that is set by the scan rate, so that in this example, the
measurements are 30 second averages:
