3.1 Precautions
(1) Be sure to check that the cell constant and the temperature coefficient are set
correctly.
(2) Check that the plastic cover (for general-purpose sensor) and outer electrode (for
high purity water measurement) are secure.
(3) Do not use the SC72 meter to measure liquids with temperatures over 80
؇C. (If the
sensor grip is immersed, liquid temperature shall be below 50
؇C.) Do not use the
meter to measure extremely corrosive liquids such as solutions of hydrofluoric
acid.
(4) Remove dirt and stains from the meter with soft tissue. If necessary, wipe the
meter case with neutral detergent.
(5) If any problem with the meter arises during measurement, refer to the
Troubleshooting section later in this manual to determine the cause.
(6) After finishing measurement, flush stains on the sensor and measured solutions
with water, and store the meter (refer to Chapter 5, “Handling of the SC72
Personal Conductivity Meter”).
