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 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. |
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 |
|
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.

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…
0.00is 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.
ZERO Key – The ZERO key will zero the scale if weight is stable, and acts as the NO or SCROLL key in the Menu mode.
TEST Key – The TEST key can be used to perform the initial power-up test sequence, recall diagnostic routines, or to view the scale configuration information. This key also acts as YES or ACCEPT in the Menu mode.
The 6700 models power up ready for weighing operations. Access the Menu mode by setting Switch 1 shown in Figure 1 or 2 to the OPEN or Menu mode position.
