Electrode Resistance:

Test C & D

8) The possible results are as follows:

• If the test rods are making good contact with the soil, all connections are correct, and the

actual value is less than 2kΩ, the measured value (RG) will be displayed in ohms (Ω).

Continue to Step 9.

• If the test rods are making good contact with the soil, all connections are correct, and

the actual value is greater than 2kΩ, "o.r." (over range) will be displayed. Recheck

connections, verify rod to soil continuity and treat if necessary, and/or use longer test rods.

9) Note the value of Rg, or press the SAVE button.The value of Rg at P 2 @67% will be

saved

to the next available memory location. Note the memory location.This is your elec-

trode or grid system resistance.
