INITIAL PREPARATION
The instrument is supplied complete with batteries. In order to place the
batteries inside the instrument follow the instructions from page 28.
To prepare the instrument for use, connect the EC probe to the input
socket on the top of the instrument.
Turn the instrument ON by pressing
On/Off.
At start-up the display will show all
the used segments for a few seconds
(or while the button is held), followed
by the percentage indication of the
remaining battery life. During
instrument startup the “ ” and
“
WAIT” tags will blink.
The meter is now ready to operate.
Submerse the probe into the solution to be tested. The
sleeve holes must be completely submersed. 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.
The auto-off feature turns the instrument off after a set period (default
20 minutes) with no button pressed to save battery life. To set another
period or to disable this feature, see SETUP menu on page 18.
The auto-off backlight feature turns the backlight off after a set period
(default 1 min) with no buttons pressed. To set another period or to
disable this feature, see SETUP menu on page 18.
