Curve display of samples that are too cold
Display of a curve
In using samples that are too cold, the maximum AutoTemp time is not sufficient to
reach the temperature adaption of the sample: By warming the sample, excess
pressure can result.
Display: Negative values of the curve are truncated and the curve emerges from
the time axis but not from the origin.
Measured values outside the measurement ranges
In the following cases, the evaluation displayed is not the measured value but “undef.“
(undefined):
- The measurement curve exceeds the measurement range at some point of its path.
- The measurement curve undercuts the measurement range at its end point.
Sample displays:
The measured value exceeds the
measurement range (overflow).
The measured value undercuts
the measurement range
(underflow).
The measured value temporarily
leaves the measurement range.
Printing
Switch on the TD 100 IR printer.
Point the controller at the printer: 10 cm to 100 cm
The controller outputs the report data of the selected sample on the
IR interface.
Printout of:
- sample information
(start date and time, final date, type, measurement range,
identification number)
- curve + BOD final value
- report printouts:
- current settings
- start information
- info
- controller info
