INITIAL PREPARATION

The meter is supplied complete with batteries.

Remove the back cover, unwrap the batteries and

install them while paying attention to polarity.

To prepare the instrument for use connect the pH electrode and the

temperature probe to the BNC and temperature sockets on the top of

the instrument. The temperature probe can be used independently to

take temperature measurements, or it can be used in conjunction with

the pH electrode to utilize the meter's ATC capability. If the probe is

disconnected, temperature can also be set

manually with the UP and DOWN keys. To

switch the instruments on, press and hold the

ON/OFF key for a fraction of a second. The

meter has a built-in protection against electro-

magnetic interference and the delayed response

of the keys assures that the commands are not

mistaken for stray signals.

pH MEASUREMENTS

To take a pH measurement remove the elec-

trode protective cap and simply submerge the

tip (4cm/1½") of the electrode and the tem-

perature probe (wherever applicable) into the

sample to be tested.

Turn the instrument ON and allow for the electrode to adjust to the

solution and stabilize.

In order to take more accurate pH measurements, make sure that the

instrument is calibrated.

It is recommended that the electrode is always kept wet and rinsed

thoroughly with the sample to be measured before use.

The pH reading is directly effected by temperature. In order for the
