5.1 Tips to Maintain Meter Performance
The SC72 meter appears to be very simple, but is a precision instrument. To ensure that
measurement accuracy is maintained, observe the following precautions regarding
preliminary setting, measurement, maintenance and storage.

Setting cell constant
• Set specific electrode cell constant.
Setting temperature coefficient
• Set liquid temperature coefficient when the standard temperature
conversion is required (see Section 2.5)
If standard temperature conversion is not requiresd, set 0.00.
• Select one of the three conductivity measurement ranges (0 to
200 ␮ S/cm, 0 to 200mS/cm, or 0 to 2S/cm) corresponding to the type of
electrode used.
Temperature measuring range is 0 to 80
؇
C.
• When measurement is completed, thoughly wash electrode to remove the
measured liquid.
• If the electrode gets stained or deformed, its cell constant may change.
In this case, calibrate the meter with standard solution (see Section 5.4).
• Avoid high-temperature, high-humidity storage locations.
