Compact Weighing Indicator
The R320 is a digital weighing indicator that is fully trade approved under OIML and NSC to 4,000 divisions. Powering options include: 12-24VDC or 4 AA batteries. It can be panel, desk or wall mounted. The unit's software is run from flash memory and can be upgraded in the field using the rin-link connection.
The programmable function key can be configured for any one of the built-in functions (Counting, Manual Hold, Peak Hold, Live Weight Totalising). The built-in RS-232 serial port is 15kV protected. Two isolated setpoint outputs provide for basic weight-control or level-control functions.
