Each data field displays the results of the specified calculation type for the
+CHANNEL input channel minus the results for the –CHANNEL input chan-
nel. For instance, if +CHANNEL is 2, –CHANNEL is 1, and CALCULATION
is AVERAGE, the data field will show the average for input channel 2 minus
the average for input channel 1. If either channel is specified as 0 it will be ig-
nored for that part of the calculation. For instance, if +CHANNEL is 1,
–CHANNEL is 0, and CALCULATION is INPUT, the data field will simply
show the resistance or voltage for input channel 1. If both channels are 0 the
data field will show 0. Measurements are displayed with the units, the channel
number or numbers for difference calculations, and calculation type.
5.3.1.3 Graph Window
The GRAPH WINDOW soft-key selects the graph type window for viewing.
The graph window shows a plot of measurements over time as shown in Figure
9. The graph type window plots all temperature measurements regardless of
channel. The vertical axis scales automatically. The time scale for the graph de
-
pends on the DELAY setting of the MEAS function (see Section 5.1.1). The
time scale, in minutes, is three times the DELAY setting or 6 whichever is
larger. The graph is cleared using the CLEAR GRAPH function described
next.
