• The “CSt” message appears for a few seconds, then
the LCD displays the not calibrated temperature
compensated EC (or TDS) reading. Pressing SHIFT
and RANGE keys, the LCD will show the temperature
compensated EC (or TDS) reading, factory calibrated
with cell value k=1. Since zero calibration is not
allowed in custom mode, if one of the above readings is
zero, the display will show “buF” message and readings
alternately.
• Using the arrow keys, adjust the displayed EC (or TDS)
measurement to the desired value.
• The maximum allowed adjustment is ± 40% around the
temperature compensated reading, factory calibrated
with cell value k=1.
