8. Operating the 2300 without a Network
The 2300 may be operated with or without a network connection, but web access and email
notifications will not be available for the latter. However, logs will still be compiled and
temporary network access will allow these to be downloaded. Once set up, the 2300 will allow
front panel setting of relay trip points and calibrations, making network access not necessary
for controlling and monitoring actions by the 2300. Front panel control and functions are
described in Sections 1.3 and 1.4. Calibrating probes and changing relay set points via the
front panel are described below. Note that only the linear (2-point) calibration and K-Factor
are supported on the front panel: non-linear and scaling factors may not be changed except
via a network. Saving and restoring the unit’s configuration is described in Section 8.3, while
setting up the unit’s IP address is described in Section 9.
8.1. Front Panel Calibration
Hit Menu, the go down one line to Calibrate/Disable Probe and hit Enter to get to a list of
the defined probes. Use the navigation buttons to select the one you want to calibrate, and
hit Enter. A new menu appears with two choices, shown in the left portion of Figure 22
below: Enable/Disable Probe and Perform Calibration. Choosing the former will allow you
to toggle the probe from enabled to disabled and back again. Choose calibrate and hit Enter
to show the right portion of Figure 22. This screen displays the existing calibration points for
this probe, with the input current on the left and the value readout to its right. Each point can
be modified or left alone: changing any value and selecting Done (scroll down to see) will
update the calibration points and reset the calibration date.
