Typical chart plot
The X-axis (time) has a default range of 5 min and the graph is incremented (drawn) at
the interval set up under SETTINGS (see Section 2.6.1). The Y-axis shows the measured
value, with respect to time.
The current, maximum and minimum values of the displayed parameter are shown to
the right of the plot and the units of the selected parameter are displayed below these
readings.
The chart can be re-set at any time by pressing the Enter key.
This provides options to either re-set the chart by pressing the scroll right key or to
return to the chart, without re-setting, by pressing the scroll left key.
A typical key sequence is shown in Figure
2.17.
If the instrument is not logging, pressing the
scroll right key, while the chart is displayed,

provides a list of all the previously saved log
files, together with an indication of the available
memory capacity (see Figure 2.18). To scroll
through the list, use the scroll up and scroll
down keys as required.
The content of the datalog files cannot be
examined but, by enabling the instrument’s
Bluetooth mode, (see Section 2.6.3), the
HygroPort I.S. application files may be used to
upload the datalog files to a PC.
While in the datalog file list screen, a shortcut
to the LOGGING Set-Up Menu is provided by
pressing the Enter key. Refer to Section 2.6.2 for
Logging set up details.
