TAKING MEASUREMENTS
• Immerse the probe into the solution to
be tested. The sleeve holes must be
completely submerged.
• Tap the probe repeatedly to remove
any air bubbles that may be trapped
inside the sleeve.
• If needed, press RANGE until the
desired EC (
AD310
), TDS (
AD410
)
or temperature range is displayed.
•
Allow for the reading to stabilize. The LCD will show
the EC (
AD310
), TDS (
AD410
) or temperature reading
in the selected range.
Notes:
•
If the meter displays only dashes “----”, the reading
is out of range.
•
If the stability indicator (hourglass symbol) blinks,
the reading is not stable.
