INITIAL PREPARATION

Each meter is supplied complete with batteries and 12 VDC adapter.

To power the instrument with batteries, remove the back cover,

unwrap the batteries and install them while paying attention to the

polarity.

If using external power supply, connect the 12 VDC adapter to the

power adapter plug.

To prepare the instrument for use, connect the pH or ORP electrode to

the connector located on the top of the instrument.

To switch the meter on, press the ON/OFF key.

The batteries charge status or "LINE" message

(if external power adapter is connected) will be

displayed on the LCD for a few seconds.

The meter is now ready to operate.

To maximize battery life, the meter is automatically switched off after 5

minutes of non-use (this feature can be disabled through setup code

20). To reactivate the instrument press the ON/OFF key.

Before proceeding with pH measurements follow the calibration proce-

dure.

Note: When the use of an alternate function (SETUP, CAL, CAL DATA

and CALT) is requested, press and hold the ALT key first and

then the second desired key.

Note: To prevent damage to the electrode, remove it from the sample

before turning the meter off.

When the meter is OFF, detach the electrode from the meter

before immersing it in the storage solution.
