Automatic zero setting is enabled for metric scales (kg) and disabled for US scales (lb).
If enabled, automatic zero setting is performed if the weight has remained below zero and stable (for example, no motion on the platter) for at least 5 seconds. The scale is automatically set to zero when the 5 seconds expires.
If the weight units change from lb to kg, this setting is enabled after a cold power start of the MP72. A scale reset (for example, via the Scale Reset STISCLRST barcode) WILL NOT enable this setting. Likewise, if weight units change from kg to lb, this setting is disabled. This setting is illegal for US (lb) scales.
