Cal Weight
The cal weight value sets the weight of product applied per revolution of the metering roller. The Viper Pro may
be used to help calculate the cal weight value by using the cal weight calibration assistance feature while
performing a catch test.
Cal Weight Calibration Assistance (Ground Drive Carts)
The following procedure steps through the Calibration Assistance wizard for the cal weight.
1. Touch within Data Box 2 on the CAN Controller Status screen. The first Node Settings screen will be
displayed.
Note:
The application type must be set for Gran 4 in order to use the cal weight calibration assistance
feature. See the Application Area section on page 51 for more information on selecting the

2. Press the Calibration Assistance button below the cal weight value. The Cal Weight Calibration screen
will display.
