Connect the analog outputs (optional)
Use double-insulated shielded cables to connect to external digital or analog circuits.
The analyzer contains two isolated analog outputs (CH1 and CH2). Use the analog outputs for
analog signaling or to control external devices.
Assign the analog outputs to a measured parameter (i.e., pH, temperature, flow or calculated
values).
Refer to
Figure 5
on page 12 to make analog output connections. Refer to
for wiring and load impedance specifications.
The default analog output is 4–20 mA (no jumpers). Install jumpers across the links as shown in
Table 3
to change the analog outputs to 0–10 V or 4–20 mA with I– terminals connected to ground
(PE) as necessary.
If the configuration of the analog output jumpers is changed, it may be necessary to calibrate the
analog outputs.
Notes:
• The analog outputs are isolated from the other electronics, but are not isolated from each other.
• The analog outputs are self-powered. Do not connect to a load with voltage that is independently
applied.
• The analog outputs cannot be used to supply power to a 2-wire (loop-powered) transmitter.

Plumbing
Make sure to use the size specifications given for tubing. The flow path must increase in diameter as
water flows through the system to prevent build-up of backpressure.
Plumbing overview
To keep the environmental rating, make sure that the plumbing ports that are not used are closed.
Tubing and plumbing hardware are supplied by the user.
