Checking Electrical Signal Continuity and Electrode Isolation
It is recommended that you routinely check the EC signal to verify that all functions are
working properly. See Maintenance and Lubrication Section for a step-by-step
procedure. It is advisable to perform this test on a routine basis (weekly or every 20-25
hours of data collection) to ensure you are obtaining reliable data.

piston (Figure 7) Set probe speed --- not recommended over 3cm/sec. This is
adjustable via the probe speed flow control on the side of the control panel. (Figure 9)
Lower the EC - Force Probe until the EC tip is at the desired starting point, usually just
below the surface of the soil. Press LOG in the EC
