9.6 PRE-TARE function
When a tare weight (rubber mat, clothes, ...) is known, this value can be entered
manually.
If the PRE-TARE key is pressed shortly, the flashing display will be shown.
The PRE-TARE function is active as long as the small arrow is pointing the ”PRE-
TARE” symbol on the display.
The value used as the last one will be displayed. If a different value is required, a
new weight value can be entered with the numerical keypad. By pressing the ENTER
key, the new value is confirmed and used. Then the entered value with minus sign
will be shown on the display.
When a person is placed on the scale plate, the display will show a weight value less
the value entered previously.
Pressing the PRE-TARE key again will return the scale to the normal weighing mode.
