7INITIAL PREPARATIONEach meter is supplied complete with batteries. Remove the backcover, unwrap the batteries and install them while paying attentionto the polarity.To prepare the instrument for use, connect the pH (or ORP) electrodeand the temperature probe to the connectors located on the top ofthe instrument.In order to achieve the maximum protec-tion against vapors and humidity, theBNC connector of the supplied pH electrodeHI1230B/C is shielded behind a water-proof sheath.Slide the protective sheath down; connectthe HI1230B/C pH electrode to the instru-ment and then slide the protective sheathback.
