Calibration & Connections
Use an external 500 g calibration weight with ±0.01 g tolerance, purchased separately. The comparator cannot be used in lb-oz or tael modes. For take-away checkweighing, follow the supplementary instructions, which apply to software p-1.01 and later, and re-zero the filled container before measurement.
No USB, RS-232C or printer connection is specified. Do not assume that an A&D cable or converter adds data output to this scale.
