6.2.3 Setting a manual temperature compensation value

To use manual temperature compensation, you need to enter the temperature value of your process

into the meter. This is the value at which reading will manually temperature compensate. You can

select any temperature between 0 and 100 °C (32 to 212 °F). Default value is 25 °C (77 °F).

To select a manual temperature compensation value

1. Switch the meter on. Press the MODE key to select conductivity or

TDS measurement mode.

2. If necessary, select ATC off as described in P7.3 on page 35. The

ATC indicator will not appear on the display.

3. Press the CAL/MEAS key to enter conductivity or TDS calibration

mode. The CAL indicator will appear above the primary display.

4. While in conductivity (or TDS) calibration mode, press the MODE

key to enter temperature calibration mode. The primary and

secondary displays show the last set temperature value.

5. Check the temperature of your sample using an accurate

thermometer.

6. Press the  or  key to offset the temperature to the measured

value from step 5.

7. Press ENTER to confirm the selected temperature and to return to

the conductivity measurement mode. See Figure 18.

The meter will now compensate conductivity or TDS readings for

manually set temperature.

NOTES

: To exit this program without confirming the manual

temperature compensation value, DO NOT press ENTER in step 7.

Press CAL/MEAS instead.

Setting the manual temperature compensation value for conductivity

will change the manual temperature compensation value for pH to the

same value, and vice versa.

6.2.4 Taking Measurements (Conductivity or TDS)

To take readings:

1. Rinse the probe with de-ionised or distilled water before use to

remove any impurities adhering to the probe body. Shake or air

dry. To avoid contamination or dilution of your sample, rinse probe

with a small volume of your sample liquid.

2. Press ON to switch meter on.

3. Press the MODE key to select conductivity or TDS measurement

mode. The MEAS annunciator appears on the top center of the

LCD. The ATC indicator appears in the lower right hand corner to

indicate Automatic Temperature Compensation.

NOTE

: For conductivity manual temperature compensation, you must de-activate the temperature

sensor built into the conductivity probe and set a manual temperature compensation. See page 14 for

more information. The ATC indicator will disappear from the display.
