Yamato Manuals & User Guides

Yamato is a diversified manufacturer recognized for its precision instruments and industrial machinery. The brand is widely known for its commercially rated weighing solutions, marketed under the Yamato and Accu-Weigh names, which serve the food service, packaging, and retail industries with high-accuracy digital and mechanical scales. These products range from compact kitchen portion control scales to heavy-duty industrial weighing platforms.

Beyond weighing technology, Yamato is a prominent name in the textile industry, producing high-speed industrial sewing machines such as overlock and flatlock interlock machines designed for garment manufacturing. The brand also encompasses climate control products, including split-type room air conditioners tailored for residential and commercial cooling needs.

• What does 'Err' mean on my Yamato digital scale?

  The 'Err' message appears when the weight on the platform exceeds 105% of the scale's maximum capacity. Remove the item immediately to prevent damage to the load cell.

• How do I fix the 'Lo' indicator on the display?

  The 'Lo' symbol indicates that the battery voltage is low. Open the battery compartment and replace the old battery (typically a 9V alkaline battery for kitchen models) with a new one.

• Why is my Yamato scale showing a negative reading?

  If the display shows '----' or a negative number, it likely means the scale was zeroed (tared) with a container that has since been removed. Press the ON/Zero key to reset the scale to zero.

• How do I switch between grams and pounds?

  Most Yamato digital scales feature a button labeled 'LB/G'. Press this key during weighing to toggle the unit of measurement between imperial (lb/oz) and metric (kg/g) units.
