OPERA TION
1.Remove the protective cap from the
bottom of the tester .
2. Press ON/OFF button to turn the tester
on.
3. Place the tip of the tester into the sample
to be measured.
4.Record the conductivity value. The
tester will automatically compensate
temperature variations.
5. Press ON/OFF button to turn the tester
off.
MAINTENANCE
If readings became unstable, clean the
probe by rinsing it in alcohol for ten
minutes. If the readings fades or disappears,
batteries should be replaced.

CALIBRA TION
1. Switch the tester on by pressing ON/OFF
button.
2.Place the tip of the probe into the
calibration solution and wait for reading
to stabilize:
- For AD203: use the 1413 µS/cm
conductivity solution.
- For AD204: use the 12.88 mS/cm
conductivity solution.
3. Using the screwdriver supplied, adjust
the calibration trimmer on the back of
the tester to match the calibration
standard value:
- For AD203: 1413 µS/cm
- For AD204: 12.88 mS/cm
4. The tester is now ready to use.
AL WAYS USE A FRESH SOLUTION
FOR CALIBRA TION.
BA TTERY REPLACEMENT
Open the battery compartment at the top
of the tester. Place the batteries noting the
polarity listed in the battery compartment.
