2.3 Probe Connections
Attach electrodes with 5-pin connectors to the sensor input by
lining the pins up with the holes in the meter port (see Figure 6).
Push the electrode connector toward the instrument.
For probes with BNC connectors, slide the connector into the
input. Push towards the instrument and turn clockwise to lock
into position.
Electrodes may be attached to both the 5-pin and BNC connectors
at the same time as long as they are not in contact with the same
solution. To select either of the connectors for measurement, go
to the
Setup 1
menu and select one.
When using half-cells, connect reference electrodes with pin tip
connectors by pushing the connector straight into the center
reference input. If using a combination electrode with a BNC or
5-pin connector, the reference pin-tip jack is not used.
