Under Capacity Limits
Under capacity indication will be given with
dashes appearing on the bottom line of the
display whenever the display is below the initial
zero value.
Over Capacity Limits
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.
Sealing
Access to the calibration switch can be secured
with a lead wire or pressure sensitive security
seal. The remote or primary indicators have no
metrological features that require the use of a
security seal.
Internal Counts
The scale has 100,000 internal counts.
Dynamic Response
The time interval when weight is applied to the
scale until a stable weight is displayed:
0–1000d,1.5 seconds
1000d+, 2.0 seconds
maximum mean average
Communications
Factory default settings: 9600 baud, 7 data bits,
even parity, 1 stop bit.
Specific cable requirements are determined by
particular POS terminal. A standard 9-pin pass
through RS-232 interface cable is necessary for
most PC interfaces. Not a null modem.
RS-232 bidirectional, configurable 1200 to 19.2K
baud. Transmits weight and scale status when-
ever ASCII "W" <CR> is sent by the POS termi-
nal. Standard ECR protocol is OPOS compatible.
For Protocol details contact factory.
