INITIAL PREPARATION
The instrument is supplied complete with rechargeable batteries. Proceed with
a complete charging process before starting (see page 63).
To prepare the instrument for field measurements close the serial communica-
tion socket with proper stopper (to ensure waterproof protection).
Connect the EC probe to the DIN connector on the top of the instrument. Tighten
the thread ring. Make sure the probe sleeve is properly inserted.
Turn the instrument ON by pressing ON/OFF key.
At start-up the display will show the Hanna logo for a few seconds followed by
the percentage indication of the remaining battery charge and the "Loading
Log..." message, then enters the measurement mode.
The auto-off feature turns the instrument off after a set period (default 30 min)
with no button pressed to save battery life. To set another period or to disable
this feature, see SETUP menu on page 35. The instrument continues to
monitor the inputs and memorize readings if the automatic logging is enabled
and started. To stop autologging press StopLog key or simply power off the
instrument by pressing ON/OFF key.
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 35.
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 repeatedly until the desired range (EC, Resistivity,
TDS, Salt) is selected on the LCD.
Allow for the reading to stabilize. The main LCD line displays the measurement
in the selected range, while the temperature is displayed on the lower LCD line.
