Note for the entering of the Pri.tc and Pri.tP :
The instrument will always try to display with the highest resolution.
eg. : for Pri.tP = 400.0, the display will be
for Pri.tP = 0400, the instrument will save the value Pri.tP = 400.0 and
we will have the same display in measure
likewise for Pri.tc = 0010, the instrument will save Pri.tc = 10.00 and in
measure we will have as display
The decimal point position is set once and for all on the configuration
saving (taking into account the display with the highest possible reso-
lution). It may in no case be modified in measure, that is to say after a
display of , if the input signal carries on increasing you will
have (display overstepping), and not
with
moving of the decimal point to the right.
Beware
: By pressing and
you can change the display resolu-
tion if you do not want to have a maximum resolution (
see p18
).
