• You will find a brief explanation of the result data shown here in the
description of the full report in section 4.2.6.
• On this subpage you have the possibility to ignore undesired peak
results (e.g. spikes) for subsequent calculations. Proceed as follows:
− Use the cursor keys to select the desired result by its VR num-
ber.
− Press the softkey <Suspend/activate> . In addition to the VR
number, the marking ! appears to show that this peak result will
be ignored in subsequent calculations (this marking can also be
canceled using the same softkey).
− Press the softkey <New calcul.> . This initiates a new calculation
whose effects on the substance evaluation are immediately ap-
parent on this page.
3 Switch to dialog page "RESULTS/Calibration"
• Press the softkey <Calibr.> . The dialog page "RESULTS" with the
subpage "Calibration" appears showing the results of the substance cali-
brations:
