SELECT MEASURE Changes the measured parameter to conductivity

(default), TDS (total dissolved solids), salinity or

resistivity. When the parameter is changed, all other

configured settings are reset to the default values.

DISPLAY FORMAT Changes the number of decimal places that are

shown on the measure screen to auto (default),

X.XXX, XX.XX, XXX.X or XXXX. When set to auto, the

number of decimal places changes automatically with

changes in the measured value.

MEAS UNITS Changes the units for the selected measurement—

conductivity: µS/cm (default), mS/cm, µS/m, mS/m or

S/m.

Option Description

TEMP UNITS Sets the temperature units to °C (default) or °F.

T-COMPENSATION Adds a temperature-dependent correction to the

measured value—linear (default: 2.0%/°C, 25 °C),

ammonia, temp table (enter x,y points in ascending

order), none, natural water or pure water. For special

applications, a user-defined linear compensation can

be entered (0–4%/°C, 0–200 °C). Natural water

compensation is not available for TDS.

CELL CONSTANT Sets the cell constant range to 0.05, 0.5, 1.0 (default),

5.0, 10.0, 0.01 Polymetron, 0.1 Polymetron, or

1.0 Polymetron. After the range is selected, the user

can enter the certified K value from the label on the

sensor cable. When the certified K value is entered,

the calibration curve is defined.

CABLE LENGTH Sets the actual length of the sensor cable to improve

measurement accuracy (default: 20 ft (Polymetron

sensors default: 5 ft)).

TEMP ELEMENT Sets the temperature element for automatic

temperature compensation to PT100 or

PT1000 (default). After selection, the user should

enter the certified T-factor from the label on the sensor

cable for best accuracy. If no element is used, the

type can be set to manual and a value for temperature

compensation can be entered (manual default: 25 °C).

Note: If a sensor with a PT100 or PT1000 element is

set to manual and the sensor is replaced or the sensor

days are reset, the TEMP ELEMENT automatically

changes to the default setting.

FILTER Sets a time constant to increase signal stability. The

time constant calculates the average value during a

specified time—0 (no effect, default) to 60 seconds

(average of signal value for 60 seconds). The filter

increases the time for the sensor signal to respond to

actual changes in the process.

10 English

Option Description

LOG SETUP Sets the time interval for data storage in the data log

—5, 30 seconds, 1, 2, 5, 10, 15 (default), 30,

60 minutes.

RESET DEFAULTS Sets the configuration menu to the default settings. All

user-defined settings are lost.

Adjust the T-factor for non-standard cable lengths

When the sensor cable is extended or shortened from the standard 6 m

(20 ft), the resistance of the cable changes. This change reduces the

accuracy of temperature measurements. To correct for this difference,

calculate a new T-factor.

Note: This procedure applies only to sensors with a PT1000 temperature element.

Sensors with a PT100 temperature element are less accurate.

1. Measure the temperature of a solution with the sensor and with an

independent, reliable instrument such as a thermometer.

2. Record the difference between the temperature measured from the

sensor and from the independent source (actual).

For example, if the actual temperature is 50 °C and the sensor

reading is 53 °C, the difference is 3 °C.

3. Multiply this difference by 3.85 to get an adjustment value.

Example: 3 x 3.85 = 11.55.

4. Calculate a new T-factor:

• Sensor temperature > actual—add the adjustment value to the T-

factor on the sensor cable

• Sensor temperature < actual—subtract the adjustment value from

the T-factor on the sensor cable

5. Enter the new T-factor in the Configure, Temp Element menu.
