6.4 21X, CR7 Dataloggers

Some Edlog dataloggers such as the 21X and CR7 do not have a burst mode.
For those dataloggers, you can use a “Loop Measurement Method” similar to
the method used with the CR200X. This method is also an option for our
CR510, CR10X, and CR23X, but only three measurements per period will be
made. FIGURE 6-3 shows a graph produced by a CR10X program with a loop
that samples 90 times. A portion of this program is shown below.
