Setup
This section provides information regarding the setup of the BenchPro Postal scale.
Unpacking the Scale
Remove all contents from the packaging. Inspect contents for damage. Contact Rice Lake Weighing Systems and the shipper immediately if items are damaged. Each carton contains the following:
- Scale with operator display attached
- In-line power supply
- U.S. power cord (three-prong AC power adapter)
- USB cable
- RS-232 cable
- Stainless steel weigh platter
Scale Setup
- Remove the protective cover from the weigh platter.
- Place the scale on a sturdy, level surface near a power outlet. Ensure the scale and weigh platter are clear of obstructions.
- Level the scale by adjusting the leveling feet until the bubble level (under the weigh platter) is within the circle.
- Tighten the jam nuts on the feet of the scale, once the scale is level.
Display Mounting
A display mount is included with each scale and comes assembled to the scale’s die-cast base housing. The included operator display uses two magnets to attach to the mount during use. The display mount can be detached from the scale and mounted to a table or on a wall.

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.
- See Section 4.2.1 on to access and configure parameters within the service menu.
- Press until displays.
- Press to enter parameter. is the default.
- Press to change it to and then press . The original calibration gravity constant setting displays.
- Press to accept. The local calibration gravity constant displays.
- Press to increase the flashing digit.
- Press to accept the value entered and move to the next digit.
- Repeat Step 6 and Step 7 until the local calibration gravity constant is complete.
- Press until displays.
- Press until displays.
- Press to accept and save the setting. The scale returns to weigh mode.
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.

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

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 for more information on troubleshooting.
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.

Communication
This section provides information regarding the connection of the BenchPro Postal scale.
Scale to Computer Port Connections
The BenchPro Postal scale can be connected to a computer using a compatible third party software program. In order for the scale to transmit the weight, identify the interface protocol included in the third party program and compare with the BenchPro Software Compatibility Chart, see Section 6.3 . The most current version of the compatibility chart can be found on the Rice Lake Weighing Systems website.

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.
Troubleshooting
Table 7-1. Error Codes
Diagnostics Menu
The diagnostic menu ( ) is used to troubleshoot scale operation. Use DIV-A or DIV-O to test functionality of the load cell.
- From the diagnostics menu, press DIVA or DIVO.A value is displayed.
- Add weight onto the scale to see if the counts increase.
- Remove the weight to see if the value returns the value displayed in Step 1.
- Calibrate the scale before determining a load cell is bad.
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.
