above the connections. Using the meter orientation shown below, the channel 2 connections
are on the left and the channel 1 connections are on the right.
Connecting Electrodes and Cables to the Meter
1. Connect the pH electrode, ion selective electrode (ISE) and/or ORP/redox electrodes to
the BNC inputs on the meter. Attach a BNC connector to the meter input by sliding the
connector onto the input, pushing down on the connector and turning the connector
clockwise to lock it into position.
2. Connect the reference electrodes to the reference inputs on the meter.
Note: If a combination electrode is used, a reference electrode is not needed.

has a clip that locks the connection and prevents it from detaching from the meter.
4. Connect the stirrer probe, Catalog Number 096019, to the stirrer input on the meter.
5. To connect a printer to the meter, connect an RS232 printer cable to the RS232 inputs on
the meter and printer. The Orion
Star series printer, Catalog Number 1010006, is
recommended for use with this meter and includes the appropriate RS232 printer cable.
6. To connect a computer to the meter, connect the USB computer cable to the USB inputs
on the meter and computer or connect the RS232 computer cable, Catalog Number
1010053, to the RS232 inputs on the meter and computer.
