Error Messages
The following table provides a guideline to enable diagnosis of possible problems indicated by the
messages generated by the OAKTON WD-35610--series benchtop meters. The table also provides
possible solutions to the problems encountered.
For conductivity measurements, the “ERR” annunciator appears on the display whenever the
calibration value input into the meter is different from the initial value displayed by more than 20%.
“ERR” displayed warns you of improper probe use, a bad calibration solution, or incorrect calibration
technique.
You will see the errors in the primary display (the row of larger digits). To eliminate the errors, switch
off the meter and switch it ON again, which makes all keys inactive. Reset the meter as described in
the Setup program P2.2 on page 18. If error persists, or the meter shows incorrect values, return the
meter.*
