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
Sealing
Internal Counts
Dynamic Response
Communications
Over capacity indication will be given with dashes appearing in the upper line of the display whenever 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 or primary indicators have no metrological features that require the use of a security seal.
The scale has 100,000 internal counts. 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
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 whenever ASCII “W” <CR> is sent by the POS terminal. Standard ECR protocol is OPOS compatible. For Protocol details contact factory.

1. Remove contents of the shipping container.
2. Inspect the scale for evidence of shipping damage. Immediately report any damage to the shipper.
1. Mount the scale on a stable, level surface that is free from air currents and vibration. Be sure the scale platter does not touch any adjacent surfaces.
2. To install the scale surface flush with a countertop, use the dimensions on the following page to guide construction.

3. Loosen the collets or jam nuts on the leveling feet. Level the scale by using the level bubble under the scale platter as a guide. Be sure all four feet are in firm contact with the counter, then tighten all collets and jam nuts.
4. Make sure all power cords, remote display cables, etc., are not touching the live weigh­ing surface.
5. Plug the unit into an appropriate voltage outlet that is properly grounded.
6. The 6720 scale can support more than one display; however, only one keypad is operable. Switch 3 selects internal or external display keypad operation.
Switch 3 Settings Closed= internal display keys operational Open = external display keys operational
The normal setting for the 6720 with the internal display is Switch 3=Closed. On 6720 w/remote only or 6710 and 6702 scales, Switch 3=Open.
Operation
Power Up Test
Sequence
If RAM or ROM error is reported, you must press the TEST key to acknowledge the condition. See “Error Codes” section.
When the scale is first powered up, it will perform a test sequence. During this sequence, the display will show the following:
• The model number and the software
version/revision level.
• A numeric counting test for all segments
of the display. During this test, a test of Random Access Memory (RAM) and a test of Read Only Memory (ROM) is performed.
If everything is OK, the display will show zero weight and the scale is ready for use.
Model 6700 Family User’s Manual
Page 9
Performing a Normal
Weighment
If the scale is outside the ± 2% zero window, center dashes are displayed “- - - -.” If necessary, reapply power to reset the initial zero setting.
1. With the scale powered on, make sure the scale platter is empty and the display is at zero. If it is not, press the ZERO key…
0.00 is displayed.
2. Place an item to be weighed on the scale platter…
The scale will display the gross weight.
3. Remove the item from the scale platter.

Diagnostics Mode
Diagnostic (DIAG) Mode
Tip: Easy access to the diagnostic mode is available directly from the front panel without opening the scale to access the Menu mode switches. See
Setup Review/Test
section.
The Diagnostic (DIAG) mode menu allows testing of specific areas of the scale’s function and viewing current configuration settings. This includes the following:
DISPLAY (DISP) – Shows the version and revision of the software, followed by a display segment test.
RAM (RA) – Performs a nondestructive test of RAM in the processor.
ROM (RO) – Performs a checksum of all loca­tions of ROM in the processor.
INPUT/OUTPUT (I/O) – Data is output by the scale and through the use of a loopback con­nector. The data is immediately read back into the receive channel and verified against what was sent. Requires a jumper (short) between transmit and receive data lines.
DIVISION TEST, w/AZT (DIV-A) – Weight data is normalized to 100,000 counts of displayed resolution. AZT (Auto Zero Tracking) is enabled.
DIVISION TEST, w/o AZT (DIV-N) – Weight data is normalized to 100,000 counts of dis­played resolution. AZT is disabled.
Viewable configuration settings include:
