12 BenchPro Series Operation Manual
3.3 Split Multi-Range and Multi-Interval
The split (

) menu option is used to configure the scale to display weight as a single range, multi-range or
multi-interval.
Single Range — a scale having one weighing range.
Multi-range — a scale having two or more weighing ranges with different maximum capacities and different scale
intervals for the same load receptor, each range extending from zero to its maximum capacity.
Multi-interval — a scale having one weighing range which is divided into partial weighing ranges each having
different scale intervals; the weighing range is determined automatically according to the load applied, on both the
increasing and decreasing load.
The default setting for the Model BP 1214-35P is 2rng , however, the unit can be configured for single and 3rng .

3.4 Gravity Mode Setting
Gravitational variations may affect the accuracy of the BenchPro Series scale upon initial installation. The scale
includes a feature that allows for adjustment of the gravity setting to the location and reducing the need for initial
calibration.
The BenchPro Series is a Legal for Trade device. Rice Lake Weighing Systems recommends contacting an
authorized scale technician to perform a calibration using certified accurate weights. The Gravity Mode must be
turned off when calibrating the scale with certified weights.
The factory default values are:
• Original Calibration Constant Setting: 9.7882 or 9.8056
• Local Calibration Constant Setting: 9.8056 (Rice Lake, Wisconsin)
To determine local gravity, use the Internet to identify local latitude and altitude. Type these values into a local
gravity calculator to determine the local gravity constant. The
BenchPro Series uses 4 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. Remove the weight platter.
2. Remove the main cover plate.
3. Locate and press the service setup switch.
4. Place the weight platter back onto the scale. The scale is now in calibration mode and
