4. Place the probe head into the solution to be measured.
5. To insure Automatic Temperature Compensation,
immerse the probe head and temperature sensor
completely. For accurate Automatic Temperature
Compensation, the temperature sensor must reach
equilibrium with the liquid being measured, this could
take several minutes.
6. Insure that there is adequate movement of the liquid
around the tip of the probe head (0.2 - 0.3 meters per
second minimum). This can be achieved by stirring the
meter in the liquid.
The meter will automatically select the range that is the most appropriate for the value being measured. For example, when measuring a 500 µS solution, the meter will select the µS range and display 500 µS as opposed to displaying 0.50 mS. To manually select the range, press and hold the Ç
MODE
button for approximately three
(3) seconds, if the value being measured is able to be displayed in the alternate range, the meter will switch ranges (see the “Range Mode Selection” section).
7. Take the desired measurements.
8. Press the ON/OFF
SET
button to turn the meter off.
To preserve battery life, always turn the meter off when
not in use.
9. Rinse the probe head with distilled/deionized water and
replace the protective cover. Always replace the
protective cover to prevent damage to the probe head.
If no button is pressed for twenty (20) minutes, the meter will turn off automatically to preserve battery life (see the
“Automatic Shutoff” section).

When the meter is turned on (by pressing the ON/OFF
SET button), the display will cycle through showing the following items:

CONDUCTIVITY CALIBRATION
One calibration point may be entered for each of the measurement ranges (0 to 1999 µS and 0.00 to 19.99 mS).
To insure accuracy:
–Always use Traceable
–Select a Traceable ®
® Conductivity Standards
Conductivity Standard with a value as close as possible to the value of the unknown sample.
–If possible, the Traceable ® Conductivity Standard and unknown sample should be at the same temperature.
The ideal temperature is 25 °C.
Previous calibration points are cleared when the meter is calibrated to a new value.

SELECTING TEMPERATURE NORMALIZATION
VALUE
Conductivity is greatly influenced by temperature. Most fluids increase in conductivity as temperature increases.
Depending on the value selected here, Automatic
Temperature Compensation (ATC) will automatically make corrections to the reading and display a value as if the sample was 25 °C or 20 °C, no matter what the actual sample temperature is. The international standard temperature normalization value is 25 °C.
The following procedure is used to change the temperature normalization value from 25 °C to 20 °C, or from 20 °C to 25 °C.

SETTING TEMPERATURE COMPENSATION
COEFFICIENT
Conductivity is greatly influenced by temperature. Most fluids 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 fluid will have a different temperature coefficient, a temperature compensation coefficient of
2.0% is a generally accepted standard compensation value. If the temperature coefficient of the solution being measured is known, that value should be entered in order to obtain the most accurate results. To take nontemperature compensated measurements, a temperature compensation coefficient of 0.0% should be entered.
The following procedure is used to set the temperature compensation coefficient.

SETTING TDS FACTOR
The Total Dissolved Solids (TDS) value that appears on the display is a result of the conductivity measurement of the fluid being multiplied by the TDS factor.
Every liquid will have a different TDS factor. An approximation of the dissolved solids for a fresh-water source can be arrived at by using a TDS factor of 0.66. If the TDS factor of the solution being measured is known, that value should be entered in order to obtain the most accurate results.

Upper Display Messages:
--- Indicates that the meter is in the manual range selection mode and the value being measured is higher than 1999 µS or 1999 ppm.
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 difficulties. Replacing the batteries with new fresh batteries will solve most difficulties.
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 flat side with the engraving. Replace the battery cover and tighten securely.
