OVEN - indicates whether the resistor oven is stable and ready for measurement. After power up, the OVEN
field will first indicate "SETTLING" while the oven warms up and settles to the proper temperature. When the
oven temperature is stable, the field will display "READY" to indicate that the Super-Thermometer is ready
for measurement. It typically takes about 30 minutes for the temperature to settle and the indication to change
to "READY." If only external reference resistors are used, it is not necessary to wait for the oven to settle.

Statistics Fields

The Statistics Fields section of the display contains user-selectable statistics fields associated with the cur-
rently displayed measurement (see Section 5.7.4.2, FIELD SETTINGS (F2), on page 48)
The Statistics Fields are displayed during measurement regardless whether Graph or Data display mode is
selected. The fields are reset when the RESET STATISTICS (F3) function key is selected.
5.6.4

Data/Graph Section

The Data/Graph section displays either a data table for each active channel as it is measured or a graph of each
channel's measurement trend. The display is toggled from Data to Graph mode by pressing the SHOW DATA/
GRAPH (F2) function.
When the data table is selected, the Up/Down arrow keys are used to scroll through the data table to view
channels off the screen. The data fields are reset when the RESET STATISTICS (F3) function key is selected.
The graph settings are configured in the Graph Settings Screen, see Section 5.7.4.4, GRAPH SETTINGS (F4),
on page 49. The graph window can be configured to display a separate graph for each channel or all chan-
nels on one graph.
5.6.5

Status and Alert Section

The Status and Alert section resides at the bottom of the display above the function keys. Depending on the
situation, the following are displayed in the Status and Alert section:
Measurement Progress Bar- indicates the progress of the current measurement
Countdown Timer- shows the time remaining before measurement stops. The timer is set in the Timing Set-
tings screen of the Measure menu see Section 5.7.3.2, TIMING SETTINGS (F2), on page 39. If measure-
ment is stopped and restarted, the timer starts over again.
Active Channel- indicates the channel currently being measured. When the measurement is completed, the
measurement value and channel number will appear in the channel measurement display.
Recording Status- indicates whether recording is in progress.
Alert Messages- displays alert messages. Alert messages only appear when the Measurement Screen is dis-
played. See the following table for a list of alert messages. When an alert message is displayed, the CLEAR
MESSAGE (F4) function key may be pressed to clear the message.

Priority Message
1 RECORDING ERROR
2 MAXIMUM TEMPERATURE
EXCEEDED
3 ITS-90 SUBRANGE EXCEEDED
4 RESISTOR DUE FOR CALIBRATION
The following function keys are located in the Measurement screen:
Description
A recording error occurred, such as memory full or USB device was
removed, that prevents further recording.
The measured temperature exceeds the Maximum Temperature
setting specified in the probe definition.
The measured temperature is outside either of the selected ITS-90
subranges in the probe definition.
The Rs resistor used for the measurement is due for calibration; as
specified by the Due Date setting in the resistor definition.
