Outline and Features

  • The HW-G series is a platform scale with a minimum resolution of 1/10000.
  • Type L scales have an LCD (Liquid Crystal Display) and use batteries as a power source to provide portability. This type can also use an AC mains adaptor.
  • Type V scales have a fluorescent display so the weighing value can be read in dim light. This type uses the AC power line as a power source.
  • The base unit (platform) is water-resistant by IP-65 specifications.
  • The counting mode function converts the total mass value (total weight) of articles to a count, assuming all items to have the same mass.
  • The percentage mode function displays the mass of an item as a percentage of a stored 100% mass.
  • The accumulation function accumulates each weighing value and counts the number of weighings.
  • The comparator function compares the display value with the upper limit value (HI) and the lower limit value (LO) and displays the result. The result can be output if option OP-03 is installed.
  • The simple batch function or full/dribble batch function can be used for filling to a target mass value. The status of a weighing value can be output if option OP-03 or OP-04 is installed. The outputs are Zero Band, Preliminary, and Final.
  • The optional RS-422/RS-485 serial interface can control up to 16 scales from a computer when this option is installed in place of the standard RS-232C serial interface.
  • Type V scales can be equipped with option OP-06, a built-in impact dot matrix printer.

Caution

Precautions for installing the scale

Consider the following conditions to get the most from your scale. The best operation is where the temperature and relative humidity are stable, the scale is installed on a solid floor or bench and there is no draft.

  • Do not install the scale in direct sunlight.
  • Do not install the scale near heaters or air conditioners.
  • Do not install the scale where there is flammable or corrosive gas present.
  • Do not install the scale near equipment which produces magnetic fields.
  • Do not install the scale where there is likely to be static electricity discharges in a place where the relative humidity is lower than 45%RH. Plastic and isolators are likely to be charged with static electricity.
  • The display unit is not water resistant. Use the display unit cover to avoid damage.
  • Do not use an unstable power source.

Precautions for operating the scale

Periodically check the scale with a known weight. Calibrate the scale before using it and after moving it to another location. Do not place anything on the pan which is heavier than the weighing capacity Do not drop anything onto the pan.

  • Do not use a sharp instrument such as a pencil or ballpoint pen to press the switches. Press the switches gently using only your finger.
  • We recommend pressing the  ZERO  or  TARE  switch before each weighing to prevent possible errors.
  • Replace used dry cells with six new ones when the BATT symbol is displayed.
  • The dry cell (battery) is size D.

Precautions for storing the scale

  • Do not disassemble the scale.
  • Do not use solvents to clean the scale.
  • For the best cleaning of the display unit, wipe with a dry lint-free cloth or a lint-free cloth that is moistened with warm water and a mild detergent.
  • The base unit can be cleaned with gentle water jets while brushing the base unit.
  • Weigh only after the unit is dry.
  • Protect the display unit from dust and water by using the vinyl cover.
  • Remove batteries from the display unit when the scale is not in use for a long time. If you leave the batteries installed they may leak and damage the scale.
