”Graph” mode
Values displayed in this mode depend on the set type of recorded value (see description
of parameters "
Channel 1
"..."
Channel 8
" in the "
Logging setup
" menu).
In the case of recording momentary values in this mode (
) the display shows
measurement results in the form of a graph, numeric form and in the form of a vertical bar.
Numeric values (displayed over the graph) and vertical bar (displayed to the right of the graph)
indicate the value corresponding to the result of the current measurement, irrespective of the
set time scale of the graph. The graphical indicator (bar displayed to the right of the graph)
always indicates the measurement result to the
graph scale range
ratio (see description of
"
Hi value
" "
Lo value
" parameters in the "
Inputs settings
" menu).
Depending on measurement inputs type
graph scale range
is defined as:
•
for I version
-
graph scale range
=
allowable measurement range
•
for U version
-
graph scale range = allowable measurement range
•
for RTD version
-
graph scale range
=
user defined range
•
for TC version
-
graph scale range = allowable measurement range

Exceeding the
graph scale range
) is announced on the bar in the form of an
arrow indicating the direction of exceeding the range. If the measurement result for the given
channel exceeds the
graph scale range
) instead of the current numeric value
(displayed in the upper right corner) the display shows a "
-Hi-
" or "
-Lo-
" message (depending
on the direction of exceeding).
