Calibrating is necessary to ensure the meter’s display produces accurate
Solutions known as ‘conductivity standards’ are made to
recipes and are used for this purpose. Refer to your meter's
instructions for the calibration procedure. To ensure the calibration
procedure is successful, note the following:
Step 1. Ensure that the calibration
solution temperature is ambient.
Step 2. To prevent contamination of
the stock conductivity standard, decant a portion (sufficient to
completely cover the electrodes) into a smaller narrow container for the
calibration procedure. Discard this once used.
Step 3. Rinse the electrode in
distilled water and gently shake off the excess water prior to placing it
in the conductivity standard.
Step 4. Leave the electrode immersed
in the conductivity standard for 5-10 minutes, or until a stable reading
is obtained, before adjusting the readout as per the instructions.
