Automatic zero setting is ±10% of maximum
capacity—active at power up. Manual zero
setting range is ± 2% of maximum capacity—
active using the ZERO key.
Under capacity indication will be given with
dashes appearing on the bottom line of the
display whenever the display is more than 2
percent below the initial zero value.
Over capacity indication will be given with dashes
appearing in the upper line of the display when-
ever the weighed item exceeds 9 divisions over
the rated capacity of the unit. The scale will use
the initial zero value for reference for over
capacity determination.
Access to the calibration switch can be secured
with a lead wire or pressure sensitive security
seal. The remote and primary indicators have no
metrological features that require the use of a
security seal.
