This tab allows access to the setup mode to make changes to parameters such as full scale, count accuracy and baud rate etc. Please refer to the 675 Series Technical Reference Manual for details on more advanced setups and configurations. An access code is required to enter the Model 672 setup mode. PPLICATION Access the Application Menu to switch to another operating mode or the factory default mode.
This chapter will give detailed operation instructions on how to use each preprogrammed mode. The Model 672 is designed to operate from the 5 soft keys or the dedicated keys of the keypad. The advantage of using the soft keys is they are placed in succession for easy operation.
b. Place the sample in the container. Key in the sample size and then press the key. The scale will accept the current weights as a sample and will display the quantity. -or- 1) If the sample size is known and no container is used: Place the sample on the scale.

Chapter 4: Calibration The calibration mode is accessible through the configuration menu or from the weigh mode. APW L CCESS ALIBRATION FROM OOKUP 1. From the main menu press the (Setup) key. 2. Press (Setup Menus) key. 3. Press (CAL) key. 4.
• A calibration weight can be applied before or after entering the calibration weight value. The display prompts you to Keyin CalWt (key in calibration weight) or Add CalWT (add calibration weight) at the appropriate time. • The digital filter is automatically set to 4 seconds during calibration. •...
Last Zero Last Zero allows span re-calibration without removing the applied test weight. The last zero established by pressing from the weigh mode will be used as the zero reference. This procedure is especially useful when performing routine tolerance checks on large capacity scales. A scale found to be out-of- tolerance can be easily calibrated without having to remove the test weights to reestablish a zero reference.
Temporary Zero Temp Zero is used to calibrate without establishing a new zero. Calibration can be performed without removing the currently applied gross load. A temporary zero is established so that test weights can be added during calibration. The original zero reference determined during the previous calibration is not affected.
Only Zero Only Zero is used for zero calibration only. This calibration procedure is primarily used for the zero reference after changing a scale’s dead-load, such as adding safety rails to a scale deck or installing a mixer motor on a hopper scale. Because the full scale capacity is referenced from the last zero calibration, performing a zero calibration helps to ensure that the full scale over-load will not occur prematurely due to the additional dead-load.
Known Loadcell Output Known LCOut is used to calibrate without test weights. The exact full scale mV/V rating must be known for each load cell. All load cells must be of the same full scale capacity. This procedure works best for hopper scales where weight is evenly distributed and signal trimming is not required.

Where applicable, enabling the restrict parameter will over-ride the current setting of other parameters. If the counting feature is enabled, NTEP requires a label on the front of the Model 672 stating “The counting feature is not legal for trade”. See Other Requirements on page 35 for other application...
NTEP C USTOM ETUP The “Custom Setup” parameter, P60205 of the information parameters, displays a list of parameters which, if configured improperly, could facilitate fraud in a legal-for-trade installation. A weights and measures inspector might check this parameter and inquire about the configuration of any parameters that appear in this list.
The Model 672 has two types of sealing provisions, a physical seal and a three event audit trail counter. Check with your local weights and measures authority to determine your requirements.
UDIT RAILS Three separate incrementing, non-resetable audit trail parameters are used by the Model 672 to indicate changes to various parameters, P60201 – OIML, P60203 – Calibration , and P60204 – Setup. An audit trail counter will increment only once upon exiting the Setup Mode and saving changes regardless of how many settings were changed.
Most NTEP requirements will also apply. See the NTEP section of this chapter for additional considerations. Enabling OIML Operation See the Model 672 Technical Reference Manual for details on enabling the OIML parameters. THER EQUIREMENTS Several parameters must be considered on an individual basis as their configuration may vary with different applications.
Chapter 6: Troubleshooting PERATIONAL RRORS ESSAGE ESCRIPTION Input signal less than negative full scale. If this is due to excessive loading, reduce the load. Otherwise check the load cell connections. If a Code02 4 wire load cell cable is being used, check that the sense jumpers are in Under place.

ESSAGE ESCRIPTION The Model 672 did not check it’s receive data register in time, thus missing a character. To prevent the problem, try reducing the baud rate portX (P200). The ‘X’ in the error message represents the COMM port number error on which the problem occurred.
