PROBE MAINTENANCE
After measurements, rinse the probe with clean water.
If a more thorough cleaning is required, remove the probe
sleeve and clean the probe with a cloth or a non-abrasive
detergent.
Make sure to reinsert the sleeve onto the probe properly
and in the right direction.
After cleaning the probe, recalibrate the instrument.

INTRODUCTION
AD310 and AD410 are portable microprocessor-based
instruments for measuring EC or TDS, and temperature.
The autoranging feature of the EC and TDS readings
automatically sets the instrument to the scale with the
highest resolution.
Measurements are compensated for temperature
effect automatically (ATC) or manually (MTC).
The temperature compensation feature can also be
disabled to measure actual conductivity or TDS.
The temperature coefficient is user selectable.
The instruments also feature a measurement stability
indicator.
25
BATTERY REPLACEMENT
When batteries become weak,
the battery symbol lights up.
It is recommended to replace the
batteries soon.
When the battery level is too low to ensure reliable
readings, the meter automatically turns off.
Battery replacement must only take place in a safe area
and using the battery type specified in this instruction
manual.
To replace rundown batteries,
remove the battery compartment
cover on the rear of the meter and
substitute all four 1.5 V AAalkaline
batteries with new ones, while
paying attention to the correct
polarity.
Reattach the battery compartment
cover.

To freeze the reading on the LCD, press
the HOLD key from measurement mode.
The “H” tag lights up.
RANGE key is active while in “Hold” mode.
Press the HOLD key again to return to normal measurements.

SETUP
Setup mode allows to view and modify the instrument
parameters.
To enter setup mode, press SHIFT and then SETUP
key from measurement mode. The “SEt” message is
displayed for a few seconds, followed by the code of the
setup item.
Select the desired setup item using the arrow keys, then
press SHIFT and then CFM to select and edit the setup
item value. Use the arrow keys to change the current
value. Press SHIFT and then CFM to confirm.

TEMPERATURE ADJUSTMENT
Temperature reading can be manually fine-tuned following
below instructions.
To enter the temperature adjustment,
press SHIFT and CAL keys from
temperature range. The LCD will
display the factory default temperature.
Adjust the temperature reading on the
LCD using the arrow keys. The maximum allowed
adjustment is ±1.0ºC around current reading.
Press SHIFT and CFM keys to confirm. The meter
returns to measurement mode and displays the new
temperature.
Notes:
•Press SHIFT and CAL keys to escape without
any changes.
• To enter temperature adjustment mode, the
probe must be connected and the ATC mode
must be set.

• When the reading is stable, the hourglass tag stops
blinking. Press SHIFT and CFM keys to confirm
calibration.
• The instrument displays the “Str” message and returns
to measurement mode.
Notes:
• The calibrated custom value is considered the
value of the calibration solution at the selected
reference temperature.
•It is possible to set the cell constant value directly,
without following the calibration procedure. To
set the cell constant enter the setup mode and
select the “CEL” item (see “Setup” section for
details).
• The temperature reading is not used during custom
calibration.

• Each meter is supplied complete with four 1.5 V AA
alkaline batteries. Remove the battery cover, unwrap
the batteries and install them while paying attention to
their polarity (also see “ Battery Replacement” section).
• Connect the supplied probe to the DIN connector and
tighten the threaded ring. Make sure the probe sleeve
is properly inserted.

• The “CSt” message appears for a few seconds, then
the LCD displays the not calibrated temperature
compensated EC (or TDS) reading. Pressing SHIFT
and RANGE keys, the LCD will show the temperature
compensated EC (or TDS) reading, factory calibrated
with cell value k=1. Since zero calibration is not
allowed in custom mode, if one of the above readings is
zero, the display will show “buF” message and readings
alternately.
• Using the arrow keys, adjust the displayed EC (or TDS)
measurement to the desired value.
• The maximum allowed adjustment is ± 40% around the
temperature compensated reading, factory calibrated
with cell value k=1.
