Alternative
:
• Press the MENU key in the results screen.
• Select 'Order', press the right navigation key and click on the re-
quired order.
Scaling
To magnify the scaling of the diagram, press the navigation key up. If
a phase vector then moves out of the diagram as a result, the maxi-
mum display range is also specified relative to the longer (no longer
visible) vector (e.g. '92% of A').
Coherence (Cross Channel)
The coherence factor is a measure of the quality of the measurement
and indicates how strongly the signals of both channels are coupled.
If the factor is close to 1, the measurement is usable.
Phase trend
If you would like to record the phase trend as a function of time or
rpm, save the individual measurements by 'Appending' to a file (see
also p. 3-29). In the Display Setup for the trend display (p. 4-20),
select either 'Time' or 'rpm' ('Phase over...' parameter). The rpm value
and the date of each measurement appear in the lower display field.
To open an individual measurement result in the trend display, press
the F key, and click on 'Details' (see below).
