Things to Know Bef ore Use
1)
A few drops of water are added to the probe cap to keep the conductivity electrode in an activated state
before the tester leaves factory. Generally, users can start using the tester directly. For conductivity
electrode that hasn’t been used for a long time, users should soak the electrode in 12.88 mS calibration
solution for 5-10 minutes or in tap water for 1 to 2 hours before use. Rinse the electrode in
distlled/deionized water after each measurement.
2)
The sensing rod of Model 2301T-S conductivity electrode is coated with platinum black to minimize
electrode polarization and expand measuring range. The platinum black coating adopted our special
processing technology, which improves the electrode performance and the firmness of the coating. If the
black sensing rods are stained, gently clean the electrode with a soft brush in warm water containing
detergent or alcohol.
3)
Things needed in addition to what’s in the box:
a)
Distilled or deionized water (8-16oz) for rinsing the probe after each test
b)
Tissue paper for drying the probe

How to calibrate
1)
Press key to switch to conductivity measurement mode (
Cond
). Rinse the probe in distilled water
and dry it.
2)
Pour certain amount of 1413
μS/cm and 12.88mS/cm conductivity calibration solution into corresponding
calibration bottles (to about half volume of the bottle).
3)
Long press key to enter calibration mode, short press to go back to measurement mode.
4)
Place the probe into 1413
μS/cm conductivity calibration solution, shake it for a few seconds and allow it
to stand still in the solution until a stable reading is reached. When stays on the LCD screen, short
press key to complete 1
st
calibration, the tester returns to measurement mode and indication icon
will appear at the bottom left of the LCD screen.
