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.
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)
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 7 to access and configure parameters within the service menu.
2. Press until

displays.
3. Press to enter

parameter.

is the default.
4. Press to change it to

and then press . The original calibration gravity constant setting displays.
5. Press to accept. The local calibration gravity constant displays.
6. Press to increase the flashing digit .
7. Press to accept the value entered and move to the next digit.
8. Repeat Step 6 and Step 7 until the local calibration gravity constant is complete.
9. Press until

displays.
10. Press until

displays.
11. Press to accept and save the setting. The scale returns to weigh mode.

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.
