Dear Customer,
Thank you for choosing a Hanna Instruments product.
Please read this instruction manual carefully before using the

instrument. If you need additional technical information, do not
hesitate to e-mail us at [e-mail].
This instrument is in compliance with the CE directives.

OPERATIONAL GUIDE

• To switch the meter on, press the ON but­ton. All the used segments on the LCD will
be visible for a few seconds, followed by a
percent indication of the remaining battery
life (e.g. % 100 BATT).

• Immerse the probe in the solution to be
tested, while paying attention to the mini­mum immersion level marked on the meter
shaft.

• Select either EC or TDS mode with the
SET/HOLD button.

• The reading is stable when the hourglass
symbol on the LCD disappears.

• The EC (or TDS) value is shown on the primary LCD, while
the secondary LCD displays the temperature of the sample.
The ATC symbol on the LCD means that measurements
are Automatically Temperature Compensated.

• To freeze the display, press the SET/HOLD button until
HOLD appears on the secondary LCD. Press either button
to return to the normal mode.

• The meter will automatically switch off after 8 minutes

of non-use.

Note: The CAL symbol on the LCD means that the meter has

been calibrated. If necessary, contact your Dealer for re­calibration.

BATTERY REPLACEMENT

• The meter displays the remaining battery percentage every
time it is switched on. When the battery level is below 5%,
the battery symbol appears on the LCD to indicate a low
battery condition. The batteries should be replaced soon.

• HI 983311 also features the Battery Error Prevention Sys­tem (BEPS), that automatically turns the meter off when
the battery level is too low to support proper operations
and ensure reliable readings.

• When batteries need to be replaced,
simply remove the two screws on the
bottom cover and replace the two 1.5V
AAA batteries with new ones, while pay­ing attention to the correct polarity.

• Battery replacement must only take place in a non-hazard­ous area and using two 1.5V AAA alkaline batteries.
