The display panel shows the relative magnitude of conductance (reciprocal of resistance) between the two test probes when these are inserted in the soil. The tester measures the dryness or wetness through soil resistance readings (0 to about 5 kilo-ohms) and indicates in dot mode by sequential lighting of LED1 through LED8.
