Hints on Fully-automatic Span Calibration

x

Fully-automatic span calibration

PSC (Not

with CAUY series) (Refer to 10.3.2 for detail.)

Default setting of PSC is ON. Upon detection of temperature change, span calibration is
automatically performed to maintain accuracy. Weight symbol ( ) blinks prior to fully-
automatic calibration.

How to skip a PSC

Press [POWER] key while Weight symbol (

)

is blinking.

How to switch off PSC

From mass display,

press [CAL] key

repeatedly until “SEttinG” appears.

→

Press [O/T] key

to display “CAL dEF”.

→

Press [CAL] key

repeatedly until

“PSC:on” appears.

→

Press [O/T] key.

“PSC-on” appears.

→

Press [CAL] key

. “PSC-oF” appears.

→

Press [O/T] key

.

Stability mark (

¨

) is added.

→

Press [POWER] key

returns “PSC:oF”.

→

Press [POWER] key

repeatedly to return to the mass display.

When PSC is off, perform span calibration according to

Span Calibration Procedure

when it is necessary.

Clock-CAL
Clock-CAL is a practical alternative that performs regular automatic span calibration
according to time setting (CAUW-D/CAUW series only, up to 3 times a day, refer to 10.3.3).
