TEMPERATURE GRAPH + DOOR OPEN BAR CHART
When you select this from the DATALOGGER screen, the Door Open bar chart is
shows at the top of the screen to associate it with a temperature disturbance
(note the correlation in Figure 10 below). A temperature reading is recorded
every 18 seconds while the temperature is outside the specification of
± 0.1°C
and each reading is shown as a single pixel.
When the temperature has settled within specification, the recording is
compressed to one pixel representing ten 18-second readings (as long as the
temperature remains in specification). This allows up to ten hours of readings to
be displayed on one screen. When the temperature moves outside specification,
for instance if the door is opened, the graph reverts to individual 18-second
readings until temperature is within specification again.
When the data is compressed or decompressed, a light dotted line is displayed
vertically on the screen to signify that the time axis is changing from 15-minute
to 2½-hour increments or vice versa. A heavy dotted line is displayed when the
incubator is switched on.
