PROBE CARE AND MAINTENANCE
Keep the probe clean. Rinse the probe twice, and
gently swirl it while readings are being taken.
For best results, soak a dry probe for at least 5-10
minutes before calibration. Rinse the probe with
clean water before storing. Never scratch the bands
with an abrasive or hard substance. Do not strike the
probe against hard surfaces or submerge the cable
for extended periods.
Do not immerse the probe in oily solutions,
aggressive solvents, or strong acids. Clean the probe
with a mild detergent or isopropyl alcohol then rinse
thoroughly. Dry storage is acceptable. Recalibrate
the probe after cleaning.
The conductivity probe features a removable probe
guard for easy cleaning. To remove the guard — grip
the yellow probe guard and twist it clockwise to
release the locking notch, and then slide it o
ff
.
NOTE: Remember to reattach the probe guard
before use – failure to do so will result in erroneous
readings!
