OPERATIONAL GUIDE
• To switch the meter on, press the ON but-
ton. All the used segments on the LCD will
be visible for a few seconds, followed by a
percent indication of the remaining battery
life (e.g. % 100 BATT).
• Immerse the probe in the solution to be
tested, while paying attention to the mini-
mum immersion level marked on the meter
shaft.
• Select either EC or TDS mode with the
SET/HOLD button.
• The reading is stable when the hourglass
symbol on the LCD disappears.
• The EC (or TDS) value is shown on the primary LCD, while
the secondary LCD displays the temperature of the sample.
The ATC symbol on the LCD means that measurements
are Automatically Temperature Compensated.
•To freeze the display, press the SET/HOLD button until
HOLD appears on the secondary LCD. Press either button
to return to the normal mode.
•The meter will automatically switch off after 8 minutes
of non-use.
