Notes: If the meter displays the top of the range blinking, the reading is out of range.
If the stability indicator “ ” blinks, the reading is unstable.
Make sure the meter is calibrated before taking measurements.
If measurements are taken successively in different samples, for accurate readings it is recommend-
ed to rinse the probe thoroughly with deionized water before immersing it into the samples.
TDS reading is obtained by multiplying the EC reading by the TDS factor, which has a default
value of 0.50. It is possible to change the TDS factor in the 0.40 to 1.00 range by entering
SETUP mode.
The probes designed to work with this instrument have an internal ID identification. Every time the
instrument detects probe changing, it reminds the user to update the cell constant of the new probe
being used and to calibrate in the appropriate EC range.
To reach this range press Mode while in Salinity range until the practical salinity scale [PSU] is
displayed.
