Notes: • If the reading is too far from the expected value, the
“ WRONG” and “ ” tags will blink. Calibration can not be
confirmed.
In this case check if the calibration solution has been used
correctly or clean the probe by following the Probe Maintenance
(see page 31).
• If the meter is in Atc or Mtc mode and the temperature is
out of the 0.0 to 60.0 ºC interval, “ WRONG”, “ºC” tags
and the temperature will blink.
• For best results choose an EC standard value close to the
sample to be measured.
• In order to minimize any EMC interference, use plastic or
glass beakers.
• It is possible to set the cell constant value directly, without
following the calibration procedure. To set the cell constant,
enter SETUP mode and select “
CELL” (see SETUP for details,
page 21).
