Attach an external module

An external module must be used as an interface between some sensor types and the logger. The
external module is mounted on the side of the logger (Figure 7 on page 14). Refer to the
documentation that is supplied with the module for mounting instructions.

Attach a sampler

The logger can attach to a Sigma 900 Standard, Sigma 900 Max, Hach SD900 or Hach
AS950 sampler for flow-paced and set point sampling. Connect the AUX port on the logger to the
auxiliary port on the sampler using a full auxiliary cable. If it is necessary to externally power the
logger while connected to an AS950 sampler, use the power input aux cable assembly. To make a
sampler program, refer to the documentation supplied with the sampler.

User interface

The indicators on the user interface show the status of the instrument and the modem. Refer to
Figure 8 and Table 3.
