Features:

• Easy to get judgment by Hi/OK/Lo or HiHi/Hi/Lo/LoLo comparator lights with buzzer.
• Foreign material detection input is newly added.
• Bar graph shows where the weight of an object falls within the OK range.
• Built-in timer controls weighing process by signal from an external photoelectric switch or by programmable weight recognition function that is beneficial for transparent objects.
• Weight, accepted piece, accumulated piece count, name of the object weighted, and standard deviation can be displayed at the touch of button.
• Up to 100 sets of target (OK weight), Hi, Lo and tare can be stored by individual code number.
• 5 digits of target and 4 digits of upper and lower limit can be set by the front key operation and number of digit and its location can be customized.
