Connect the EC/TDS probe to the
7-pin connector located on the top
of the instrument. Tighten the
threaded ring.
Make sure the probe sleeve is prop-
erly inserted, as shown in the figure.

Press the ON/OFF key to turn the meter on.
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 the meter displays "
----" the reading is out of range.
II
If the reading is unstable, the stability indicator " " blinks.
III
The "gm" indication on the LCD means g/L.
IV
Make sure the meter is calibrated before taking measurements.
V
If measurements are taken successively in different samples, to
have accurate readings it is recommended to rinse the probe
thoroughly with deionized water before immersion in the samples.

To maximize battery life, the meter is automatically switched off
after 5 minutes of non-use. To reactivate the instrument press
the ON/OFF key. This feature can be disabled by entering the
setup mode and selecting the "AoF" item (see SETUP for de-
tails).

VII TDS reading is obtained 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 0.80 range by entering
the setup mode and selecting the "tdS" item (see SETUP for
details).
