2 levels of data protection.
1st level 0 to 4999 com-
pletely protected. 2nd level
5000 to 9999 access to
programming is protected,
while alarm set-points are
directly programmable
from the measuring mode.
Programmable and inde-
pendent per each channel
(only in case of dual fre-
quency meter), from 1 to
9999.
Programmable among Hz,
kHz, rpm, krpm, rph, krph,
and independent per each
channel (only in case of
dual frequency meter).
Selection of the decimal
point, min value and max
value of the input range
(expressed in engineering
units). Selection of the dec-
imal point, min value and
max value of the displayed
range correspondent to the
input range.
Programmable and inde-
pendent per each channel
(only in case of dual fre-
quency meter).
