Connecting Electrodes and Accessories
Connect the accessory connectors at the rear of the instrument panel. During operation, it is
important that water does not get onto the BNC connector. Also avoid touching the
connector with soiled or wet hands.
Connecting the Sensor Electrode
Slide the electrode connector over the meter BNC socket marked “INPUT”. The meter can
accept a standard pH or ORP electrode with a BNC connector. Align the slot of the electrode
connector with the posts of the socket. Rotate the connector clockwise until it locks. For a
separate reference half-cell electrode, push the reference electrode pin into the meter jack
marked “REF”.
Connecting the ATC Temperature Probe
Insert the temperature probe into the connector marked “ATC”.
Connecting the AC Adapter
Slide the jack of the AC adapter into the meter input marked “DC” until it is firmly seated.
Ensure the power is switched off before installation and the correct voltage adapter is used.
Connecting a Chart Recorder
Chart recorders or external output devices can be connected to the meter for continuous
printout. Plug in the input connector and ground pin of the chart recorder into the ports
marked “REC” and “GND” respectively.
