Basic operations8● Connecting an electrodeTo perform calibration/ measurement, it is necessary to use the appropriate electrode formeasurement parameter. Recommended electrodes for various sample are listed in ourproduct catalog. Use the following procedure to correctly connect the electrode to theinstrument:1. Insert the electrode connector by fitting its groove with the connector pin of theinstrument (refer below table).2. Turn the electrode connector clockwise by following the grooves.3. Slide the connector cover on the connector.4. When using a combination electrode equipped with a temperature sensor, insert thetemperature jack (T) to the ATC socket on the meter.CH1 CH2pH Electrode Conductivity ElectrodeElectrode connectorTemperature jack (T)
