OPERATION

This section contains basic operating instructions, to insure accurate results and for more advanced functions, refer to the additional sections that follow.

1. Remove the protective cover from the probe head.

2. Turn the meter on by pressing the

ON/OFF

SET

button.

3. Place the probe head into the solution to be measured.

4. 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.

5. 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

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).

6. Take the desired measurements.

7. Press the

ON/OFF

SET

button to turn the meter off. To preserve battery life, always turn the meter off when not in use.

8. 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).

POWER ON DISPLAY SEQUENCE

When the meter is turned on (by pressing the

ON/OFF

SET

button), the display will cycle through showing the following items:

All Segments - Display check tnr Normalization temperature value (see the “Selecting Temperature Normalization Value” section) tco Temperature Compensation Coefﬁ cient value (see the “Setting Temperature Compensation Coefﬁ cient” section). ran Range display mode (see the “Range Mode Selection” section).

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® Conductivity Standards –Select a Traceable® 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.

1. Remove the protective cover from the probe head.

2. Turn the meter on by pressing the

ON/OFF

SET

button.

3. Place the probe head into the Traceable® Conductivity Standard.

5. 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.

6. Press and hold the

button for approximately

SELECTING TEMPERATURE NORMALIZATION VALUE

Conductivity is greatly inﬂ uenced by temperature. Most ﬂ uids 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.

The temperature normalization value selected will be the default value until changed.

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 nontemperature 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.

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:

Indicates that the temperature sensor is damaged.

Indicates that the temperature of the solution

being measured is below the measurement range of the unit.

Indicates that the temperature of the solution

being measured is above the measurement range of the unit.

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.
