11.5.5 About Error Messages
The electronics unit can be reconfigured for new parameters at your option. However, if some parameters
you set up conflict, or when an erratic condition arises, the LCD display will tell you with an error message
from Table 11.1 below.

Description
Remedy
An attempt is made to re-
write a parameter while pa-
rameters are write-protected.
(In the standard model,
write-protect feature is set in
OFF and will not appear.)
Backup data retained for
parameters has been
damaged.
Some of the backup data
retained for the display
mode, accumulate total flow
reading, or resettable total
flow reading have been
damaged.
Pulse weight "Pu" setting is
too small with respect to
meter factor "F" and conver-
sion factor "H".
Analog output level is exce-
eded 120% of full scale for
either reason:
①
Flowrate excessive
②
Analog full scale setting
too small
Pulse "OFF" width in the
factored pulse output falls
short of 1 msec for either
reason:
①
Flowrate excessive
②
Factored pulse width
setting too great
Supply voltage has dropped.
Can be reset by placing No.
1 of display board SW2 in
OFF. (This enables you to
change parameters.)
CPU initialization and then
reconfiguration of
parameters are required.
Can be restored with MODE
switch, but the accumulated
total flow and resettable total
reading will be reset to 0.
Change the setting to an
appropriate value that the
relationship between F, H,
and Pu satisfies the following
formula:
F

H
≦

①
: Reduce flowrate.
②
: Select an appropriate
analog full scale setting
relative to the flowmeter
specification.
①
: Reduce flowrate.
②
: Choose an appropriate
factored pulse width
"Pon" relative to the
flowmeter specification.
Replace the battery with a
new one.
