Reference Temperature
(
Linear
or
Non-Linear
temperature compensation only)
Note:
ISO 7888-1985 requires a reference temperature of 25 °C.
To set the reference temperature:
• Press
while in
Conductivity
mode.
• Press
.
• Use
or
to highlight the
Temperature
option.
• Press
and then use
or
to highlight
the
Reference Temperature
option.
• Press
and then use
or
to increase /
decrease the value.
• Press
to save or press
to cancel operation.
Compensation Coefficient
(
Linear
temperature compensation only)
The temperature coefficient is a factor used to express the rate a solution’s conductivity increases with an
increase in temperature and is expressed as a % increase in conductivity, for a temperature change of 1 °C. The
coefficient differs for different binary solutions. For typical aqueous dilute salt mixtures, 1.9 %/°C is used.
Ultrapure water is 5.5 %/°C.
To set the compensation coefficient:
• Press
while in
Conductivity
mode.
• Press
.
• Use
or
to highlight the
Temperature
option.
• Press
and then use
or
to highlight
the
Compensation Coefficient
option.
• Press
and set the desired compensation coefficient
using
or
to increase/decrease the value.
• Press
to save the current value or press
to
cancel operation.
To set the
temperature compensation
mode:
• Press
while in
Conductivity
mode.
• Press
.
• Use
or
to highlight the
Temperature
option.
• Press
and then use
or
to highlight
the
Temperature Compensation
option.
• Press
and then use
or
to select
Linear
,
Non-Linear
or
Disabled
option.
• Press
to confirm your selection or press
to
cancel operation.
Note
: Whatever form of compensation is used, the reading will not be as accurate as taking a reading of the
sample’s conductivity at the reference temperature.
Temperature Unit
The user can choose from the
Celsius
,
Fahrenheit
or
Kelvin
temperature units.
To set the temperature unit:
• Press
while in
Conductivity
mode.
• Press
.
• Use
or
to highlight the
Temperature
option.
• Press
and then use
or
to highlight
the
Temperature Unit
option.
• Press
and then use
or
to select
Celsius
,
Fahrenheit
or
Kelvin
unit.
• Press
to confirm your selection or press
to
cancel operation.
