2.3 Probe Connections
2.3.1 Connecting pH Probes
Attach electrodes with 5-pin connectors to the sensor input by
lining the pins up with the holes in the meter port (see Figure 4).
Push 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.
Note: If using a combination electrode with a BNC or 5-pin connector,
the reference pin-tip jack is not used.
2.3.2 Connecting the Temperature Probe
Hach electrodes with the 5-pin connector have the temperature
sensing unit included in the electrode probe. If using an electrode
with BNC connector, connect a Hach temperature probe to the
5-pin connector. Alternatively, measure the temperature manually
and enter the value as the default temperature on the meter.
2.4 Printer and Computer Connections
The meter can send data to a computer or printer via the 9-pin
serial port (see Figure 4). The printer cable and computer
cable are different. The printer cable is a 9-pin to 25-pin cable
and the computer cable is a 9-pin to 9-pin cable. Be sure to use
the correct cable.
The meter can print to serial printers without an adapter. For
parallel printers, a converter and cable adapter are required. The
Citizen PN60 printer (Cat. No. 26687-00) requires a special
Citizen adapter. Pressing the
PRINT
key will send the currently
