6.5.2 TEMPERATURE GRAPH + DOOR OPEN BAR CHART
When you select this from the DATALOGGER screen, the Door Open bar chart is shown at the top of the
screen to associate it with a temperature disturbance (see Fig. 6-6 on p. 38). 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 (10) 18-second readings (as long as the temperature remains in specification). This allows up
to 10 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 18-second to 10 x 18-second increments or vice versa (see
Fig. 6-7 on p. 38).
A heavy dotted line (not shown) is displayed when the incubator is switched on.
