Do not use the adapter when using alkaline batteries
(primary batteries). Use the adapter only when using
rechargeable batteries.

Caution for Usage
!
CAUTION
The calibration solution and cleaning solution must be changed often, depending on
the frequency of usage.
Calibration before each use ensures a more accurate measurement data.
The sensor must be rinsed with cleaning solution before and after each step of
calibration and measurement procedures..
Wipe off the surface of the sensor with tissues after each step of calibration and
measurement procedures.
Before calibration and measurement, wait for an one minute after the sensor has
been inserted in the sample for the sensor to be stabilized.
After calibration is completed, measure the standard solution to check the accuracy
of the calibration. If the result is over the error range (±10%), polish the surface of the
sensor or change the calibration solution before re-calibrating.
The sensor should be at the same temperature as the sample and calibration solution
at calibration and measurement procedure.
Itf the temperature gap is above 10
between the sample and the sensor, may be
℃
decreased accuracy of measurement results.
The recommended temperature range of samples to be measured is 10
~30
.

℃
Polish the surface of the sensor frequently with sand paper. Impurities on the surface
may impede accuracy of measurements. After polish the surface of the sensor
immerse the sensor in cleaning solution for an hour before reuse.
