BenchPro BP-P Postal Bench Scale

4.3 Gravity Mode Setting
Gravitational variations may affect the accuracy of the BenchPro scale upon initial installation. The scale includes a feature which allows for adjustment of the gravity setting to the location and reducing the need for an initial calibration pending regulatory requirements in the region.
The BenchPro is a Legal for Trade device. Rice Lake Weighing Systems recommends contacting an authorized scale technician to perform a calibration using certified test weights.

IMPORTANT: Gravity compensation must be turned off when calibrating the scale with weights.
The factory default values are: · Original Calibration Gravity Constant Setting: 9.7951 or 9.8056 · Local Calibration Gravity Constant Setting: 9.8056 (Rice Lake, Wisconsin) NOTE: The original calibration gravity constant is the location the test weights were placed on the scale to calibrate it. The local calibration gravity constant is the location the scale is to be used.
To determine the local calibration gravity constant, use the Internet to identify the local latitude and altitude. Type these values into a gravity calculator to determine the local calibration gravity constant. The BenchPro uses four values to the left of the decimal place and it may be necessary to round the values prior to input. Use the following steps to modify the local gravity () constant setting.
1. See Section 4.2.1 on page 11 to access and configure parameters within the service menu.

Below are links to websites used to determine local latitude and altitude. Please note these website address's are provided for reference only and may change.
National Geophysical Data Center: www.ngdc.noaa.gov.
Measurement Canada: www.ic.gc.ca.
Map Coordinates: www.mapcoordinates.net/.
Once local latitude and altitude have been determined, use the following link to calculate local gravity: www.sensorsone.com/local-gravity-calculator/.
IMPORTANT: It is up to the authorized scale dealer to ensure the device is accurate at the intended point of use, especially for Legal for Trade installations.

5.0 Calibration

This section provides information regarding the calibration of the BenchPro Postal scale.

5.1 Span Calibration
The BenchPro allows for calibration with weight values other than max capacity. Table 5-1 displays the alternate calibration weights for each model.
Calibration should only be performed using certified tests weights and performed by the local scale distributor.
NOTE: Turn off Gravity Compensation, see Section 4.3 on page 14 prior to performing a calibration using certified weights. The default capacity () setting is in lb if using the lb scale, otherwise the default capacity setting is in kg if using kg calibration weights, change the  to the appropriate scale capacity of the scale model. The model number of the scale is located on the serial tag on the bottom of the scale.

18. Place the calibration weight on the scale and wait for the value to stabilize.

19. Press

to accept. The calibration data is saved and the scale returns to the weigh mode.

The weight value displayed must match the value of the calibration weight used. If not, perform the calibration a second time and follow each step carefully. If  displays, there is a calibration error. Ensure the correct calibration weight value was selected in comparison to the actual calibration weight used. See Section 7.1 on page 26 for more information on troubleshooting.

5.2 Linear Calibration
IMPORTANT: Only perform a linear calibration function if instructed by Rice lake Weighing Systems and an authorized scale technician.
The BenchPro includes an optional linear calibration feature. This is an additional feature to perform after a span calibration has been completed at maximum capacity and linear calibration is performed with two lower calibration weight values.

Seal Scale Lift the weigh platter from the scale.
Guide sealing wire through the drilled hex screw and through the PCB compartment door handle.
Seal the wire to secure.

7.0 Maintenance and Troubleshooting

Prior to calling customer support, have the software type and software version number available. These are displayed briefly when powering on the scale.
7.1 Troubleshooting

Error Code

Description

Possible Cause

Corrective Action


 
     
--

Calibration error

Ensure the calibration value selected is equal to Repeat calibration; Replace load cell the weights being placed on the scale for performing span calibration; damaged load cell

Power up or initial zero error Semi-auto zero error

Upon power up, weight or item on the platform is Remove weight and power cycle the scale greater than  setting
When pressing the zero button, the weight value -displayed is greater than the % in Zero configuration

Configuration error Overload error

Invalid configuration settings Too much weigh applied

Check configuration settings Perform calibration, check LC mV

Memory error

PCB is corrupt

Replace main PCB

Low battery A/D Conversion error

Battery power voltage is below 4.2 V --

Replace batteries Calibrate, replace main PCB

Failure at initial power up

--

Power cycle the unit by unplugging the power adapter from the outlet or removing the batteries for 30 seconds; Replace the batteries or plug the adapter back in and turn the scale on

Scale is weighing properly up to a Overload stop has been tampered with and certain weight but will not weight to adjusted too far in
full capacity

Load scale to 125% of capacity, adjust overload
screw so it's touching the bottom of the load cell, back screw off 1/6'' of a turn then Loctite in place

Table 7-1. Error Codes

7.1.1 Diagnostics Menu The diagnostic menu () is used to troubleshoot scale operation. Use DIV-A or DIV-O to test functionality of the load cell.
1. From the diagnostics menu, press DIVA or DIVO.A value is displayed. 2. Add weight onto the scale to see if the counts increase. 3. Remove the weight to see if the value returns the value displayed in Step 1. 4. Calibrate the scale before determining a load cell is bad.

7.1.2 Power Troubleshooting
Loss of power to a USB device or intermittent loss of power to the scale causes the scale to turn off. The display may remain at the last display state. Power cycle the scale to reactivate the display.

Maintenance and Troubleshooting

7.3 Periodic Maintenance
Refer to the following table for periodic maintenance guidelines:

Task Routine cleaning Ensure scale is level Verify power
Test repeatability and accuracy Inspect for damage
Calibrate Certification

Process

Daily/Weekly

Remove dirt, dust and debris

X

Check level and adjust scale feet as needed

X

If AC powered, ensure the power LED illuminates

If battery powered, ensure  doesn't show on the display

X

(see Table 7-1 on page 26)

Place a minimum of 5% of full scale capacity on the scale 3 times in each quadrant

Check AC power adapter and scale for visible damage or missing parts Inspect batteries for corrosion or damage

Perform certified calibration

Review and renew test weight certifications
