User Guide

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 needed, press the RANGE key repeatedly until the

desired range (EC, TDS, NaCl) is selected on the

LCD.

Allow for the reading to stabilize. The upper

LCD displays the measure in the selected

range while the temperature is displayed on

the lower LCD.

Notes

I 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.

VI 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).

VII When the use of an alternate function (FNC, CFM,FIXED,TC and

CALT) is requested, press and hold the ALT key first and then

the second key.
