2.) If necessary, clean the probe with alcohol to re-
move any residual oils. Rinse the electrode tip in de-
ionized (or distilled) water and then rinse it in the
calibration standard.
3.) Switch unit on with the ON/OFF key. Place
probe tip into a container of calibration standard
(2.76 mS/cm). Take care that the 4 exposed elec-
trodes on the tip are not touching the side or bottom
of the container holding the buffer solution. Wait for
display to stabilize (display value is unchanged and
stable for 3 seconds).
4.) Pressing either calibration key will put the meter
into CALIBRATION mode. Press the INC or DEC
key to adjust the reading. If a key is held down, the
adjustment will happen more rapidly.
5.) When the EC of the calibration standard is
reached, release the keys for 3 seconds. The tem-
perature reading will briefly flash “CO”. The Water-
proof EC Tester accepts the calibration value and
returns to MEASUREMENT mode.
Important - The meter will NOT calibrate to the com-
