The R420-K401 indicator introduces a fresh new design concept to Rinstrum's series of digital indicators. It is a variant of the R420-K402 indicator minus the ability to add Calendar modules.

The R420’s Digital Counter tracks all changes made to TRADE settings only. This allows alterations on NON-TRADE settings without forcing a re-certification and full weights test as would happen when a physical seal was broken.

The exceptionally large LCD display has very bright LED backlighting to ensure easy reading in all lighting conditions - including bright sunlight. There are three separate lines of data that can be viewed: 29mm high main digits, 18mm high secondary digits/text and a third line of 6mm high digits for displaying product names, totals, etc.

The silicon keypads offer superb feedback with a precise soft-touch operation. There are three assignable function keys to alleviate confusion when performing special keystroke operations.

All R420 series indicators feature our rin-LINK innovation for direct PC access to all set-up and configuration settings via a magnetically latched data cable connected directly to the display glass. The R420 firmware can be updated (flashed) with dedicated software functionality at a later date with a minimum of fuss.

The unit is fitted with two on-board serial output ports (RS232 bi-directional & RS485 transmit only). There are various standard printing formats available for the RS232 output.
