OPERATIONAL GUIDE
TAKING MEASUREMENTS
• Turn the meter on.
• Immerse the tip (5 cm/2”) of
the probe in the sample.
Note:
For better accuracy, allow
the reading to stabilize. Any
initial variation may be due
to temperature compensa-
tion and the fact that the
probe is adjusting itself to
the new sample.
For better accuracy, a frequent calibration is recommended.
Moreover, the instrument should be recalibrated at least once
a month, after cleaning the probe or replacing the batteries.
• Turn the meter on.
• Press and hold the ON/OFF
button for approx. 3 seconds.
The display will start blinking
“1500 ppm” for
HI 981409
and “5.00 ms” for
HI 981410
to indicate that the calibra-
tion mode has been entered.
• Immerse the probe in the proper cali-
bration solution: use
HI 70442
(1500
ppm) for
HI 981409
, or
HI 70039
(5.00 mS/cm) for
HI 981410
.
• Stir gently and wait for approximately
20 seconds for the meter to perform
the automatic calibration.
Note:
The probe should be submerged
approximately 5 cm (2”) in the
solution.
• Once the display stops blinking, the
instrument is calibrated and ready to
use.

Electrical Safety
Recommendations for Users
Before using this product, make sure that it is entirely suitable for the environment in
which it is used. Operation of this instruments in residential areas could cause unacceptable
interference to radio and TV equipment.
The metal band at the end of the probe is sensitive to electrostatic discharges. Avoid touching
this metal band at all times. During operation, ESD wrist straps should be worn to avoid possible
damage to the probe by electrostatic discharges.
Any variation introduced by the user to the supplied equipment may degrade the instrument’s
EMC performance. To avoid electrical shock, do not use this instrument when voltage at the
measurement surface exceed 24 Vac or 60 Vdc.
Use plastic beakers to minimize any EMC interferences.
To avoid damage or burn, do not perform any measurement in microwave ovens.

ERROR CODES
BATTERY REPLACEMENT
When the batteries are weak, EC and TDS
will
display the warning symbol “Eb”.
To replace the batteries, remove the rear panel and replace
both batteries, while paying attention to their polarity.
Batteries should only be replaced in a safe area and using
1.5V AA alkaline batteries.
Note
: Once the batteries have been replaced, turn the meter
OFF and then ON again. Wait for 30 seconds to allow
the meter to complete the selftest before performing a
new calibration.
Error in calibration, wrong buffer solution
or probe requiring cleaning or replacing.

PROBE CONNECTION & MAINTENANCE
In order to protect the DIN connector against
vapors and humidity, the meter is provided
with a waterproof sheath.
• Slide the protective sheath down, connect the
HI 1220
probe to the DIN connector and then slide the protective
sheath back up. To ensure maximum protection, make
sure the connector is completely covered.
• If the meter is not used for a long time, it is recommended
to clean the internal sensitive pins with alcohol. Immerse
the tip of the probe up to the air-vent hole in alcohol for
a few minutes.
• After use, clean the probe with tap water and dry it.
• After prolonged use, clean the probe by immersing it in
HI 7061
cleaning solution for 30 minutes.
