Seaward DO7010 - Manual (Page 27)

Then the DO7010 performs a checking routine and display the measurement result of
a built-in 5 m
Ω resistor.
If the measurement result is within the tolerances (uncertainty of DO7010 unit + built-
in resistor equal about +/- 19 digits) then the green LED lights, if not the red LED
lights.
If red LED lights, we recommend to stop operating the unit and to send it back to our
Service department for diagnostic.
