ORP MEASUREMENTS

Connect the ORP electrode to the meter and press the ON/OFF key.

The meter automatically sets the mV range.

If the electrode is not connected the LCD will display the "no probe"

message and then dashes.

To take ORP measurements, remove the electrode protective cap and

simply submerge the tip (4 cm/1½") of the electrode in the solution

to be tested, stir gently and allow for the reading to stabilize.

Note: The ORP electrodes are not provided with the temperature

sensor.

By continuously pressing the DISPLAY key the following information

will be displayed on the primary LCD:

• Time

• Day / Month

• Year

Pressing DISPLAY again, the meter returns to mV reading.

Note: If measurements are taken successively in different samples, it

is recommended to rinse the electrode thoroughly with deion-

ized water or, if not available, tap water first and then with

some of the next sample to condition the electrode before

immersing it in the sample to be tested.

TEMPERATURE MEASUREMENTS

The temperature sensor is integrated in the pH electrode.

Immerse the pH electrode in the solution, wait a few minutes for the

temperature to stabilize and press the ON/OFF key. The temperature

will be displayed on the secondary LCD.

Note: If temperature measurement is out of range the LCD will

display "- - -".
