5.1 For Optimum 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.

Table 5.1 Observe the following precautions
Preliminary
setting
Setting cell constant
• Set specic electrode cell constant.
Setting temperature coecient
• Set liquid temperature coecient when the standard temperature
conversion is required (see Section 2.5)
If standard temperature conversion is not requiresd, set 0.00.
Measurement •
Select one of the three conductivity measurement ranges (0 to
200µS/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.
Maintenance •
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).
Storage •
Avoid high-temperature, high-humidity storage locations.
