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
Coping action
PA.Err.
Parameter setup
error
An attempt is made to rewrite a
parameter while parameters are write-
protected.
(In the standard model, write protect
feature is set in OFF and will not appear.)
Can be reset by placing No.
1 of display board SW2 in
OFF. (This enables you to
change parameters.)
PA.Err.1
Parameter error 1
Backup data retained for parameters
has been damaged.
CPU initialization and then
reconfiguration of
parameters are required.
PA.Err.2
Parameter error 2
Some of the backup data retained for
the display mode, accumulate total flow
reading, or resettable total flow reading
have been damaged.
Can be restored with MODE
switch, but the accumulated
total flow and resettable total
reading will be reset to 0.
PA.Err.Pu
Pulse weight error
Pulse weight "Pu" setting is too small
with respect to meter factor "F" and
conversion factor "H."
Change the setting to an
appropriate value that the
relationship between F, H,
and Pu satisfies the following
formula:

AnA.Err
Analog output error
Analog output level is exceeded 120%
of full scale for either reason:
①
Flowrate excessive
②
Analog full scale setting too small
①
: Reduce flowrate.
②
: Select an appropriate
analog full scale setting
relative to the flowmeter
specification.
Out.Err
Pulse output error
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
①
: Reduce flowrate.
②
: Choose an appropriate
factored pulse width
"Pon" relative to the
flowmeter specification.
BATT
Battery life
Supply voltage has dropped.
Replace the battery with a
new one.
