SETTING TEMPERATURE COMPENSATION
COEFFICIENT
Conductivity is greatly infl uenced by temperature. Most
fl uids increase in conductivity as temperature increases.
The value set here will determine how much the
Automatic Temperature Compensation (ATC) feature will
adjust the value for every 1 °C in order to automatically
make corrections to the reading and display a value as
if the sample was 25 °C or 20 °C (see the “Selecting
Temperature Normalization Value” section), no matter
what the actual sample temperature is.

Although every fl uid will have a different temperature
coeffi cient, a temperature compensation coeffi cient of
2.0% is a generally accepted standard compensation
value. If the temperature coeffi cient of the solution being
measured is known, that value should be entered in
order to obtain the most accurate results. To take non-
temperature compensated measurements, a temperature
compensation coeffi cient of 0.0% should be entered.

The following procedure is used to set the temperature
compensation coeffi cient.

1. Turn the meter on by pressing the

ON/OFF

SET

button.

2. Press and hold the

ON/OFF

SET

button for approximately

three (3) seconds,

P1.0 will appear at the bottom of

the display.
3. Press the

ON/OFF

SET

button three (3) times, the

temperature coeffi cient value will fl ash on the display.
4. Press the and/or

HLD/CAL

buttons to adjust the

display to the desired temperature coeffi cient value.
5. With the desired temperature coeffi cient value
appearing, press the

ON/OFF

SET

button one (1) time,

P1.0 will appear at the bottom of the display.

6. Press and hold the

ON/OFF

SET

button for approximately

three (3) seconds, the meter will return to the
measurement display.

The temperature coeffi cient value selected will be the
default value until changed.

RESET TO FACTORY DEFAULTS
Resetting the meter will clear all calibration data and
reset the user selectable values to the factory defaults.
Factory defaults are as follows:
Temperature display:

°C

Normalization Temperature: 25 °C
Temperature Coeffi cient:

2.1%

The following procedure is used to reset the meter to the
factory default values.

1. Turn the meter on by pressing the

ON/OFF

SET

button.

2. Press and hold the

ON/OFF

SET

button for approximately

three (3) seconds,

P1.0 will appear at the bottom of

the display.
3. Press the button one (1) time,

P3.0 will

appear at the bottom of the display.
4. Press the

ON/OFF

SET

button, the

n

will fl ash on the display.

5. Press the button, the

y

will fl ash on the display.

6. With

y

appearing, press the

ON/OFF

SET

button,

P3.0

will appear at the bottom of the display and the values
will have been reset to the factory defaults.
7. Press and hold the

ON/OFF

SET

button for approximately

three (3) seconds, the meter will return to the
measurement display.

DISPLAY MESSAGES
Upper Display Messages:
--- Indicates that the meter is in the manual

range selection mode and the value being

measured is higher than 1999 µS.

E03 Indicates that the value of the solution being

measured exceeds the measurement range of

the unit.

E04 Indicates that the value of the solution being

measured exceeds the measurement range of

the unit based on a temperature measurement

error (see the “Lower Display Messages” section).

Lower Display Messages:
E0

1

Indicates that the temperature sensor is damaged.

E0

2

Indicates that the temperature of the solution

being measured is below the measurement

range of the unit.

E0

3

Indicates that the temperature of the solution

being measured is above the measurement

range of the unit.

ALL OPERATION DIFFICULTIES
If this meter does not function properly for any reason,
replace the batteries with a new, high quality batteries
(see the “Battery Replacement” section). Low battery
power can occasionally cause an number of “apparent”
operational diffi culties. Replacing the batteries with new
fresh batteries will solve most diffi culties.

BATTERY REPLACEMENT
An erratic display, faint display, no display, or a battery
symbol appearing on the display are all indicators that
the batteries need replacement. The battery cover is
located at the top of the unit. Unscrew the battery cover
by turning it counter-clockwise. Remove the exhausted
batteries and replace them with four (4) new #357/LR44
size silver oxide batteries. Make certain to insert the
new batteries with the proper polarity as indicated by the
“+” and “–” symbols in the battery compartment. The
“+” side of the silver oxide battery is the fl at side with
the engraving. Replace the battery cover and tighten
securely.
