5.6. ZERO Key
When an empty scale has drifted away from a true zero reading, this key is used to
perform a zero adjustment on the scale display. In the K35x versions, the zero
adjustment is stored when power is removed and is re-used when next powered up.
The amount of weight that may be cancelled by the <ZERO> key is limited via an
item in the Setup of the instrument. Refer to Z.RANGE (Allowable Zero Operating
Range) page 34 for more information.
Long Press: When the indicator is set to Industrial mode a long press of the
<ZERO> key will remove any stored zero adjustment. Refer to Industrial vs OIML
and NTEP Modes page 25 for more information on modes.
This key is used to temporarily set the scale to zero (such as cancelling the weight
of a carton before performing a filling operation). The display will show the Net
weight and the NET annunciator will be lit.
The <TARE> key can operate in all modes (i.e. Industrial, OIML and NTEP). Refer
to Industrial vs OIML and NTEP Modes page 25 for more information.
The weight tared is deducted from the allowable range of the scale, reducing the
maximum weight that can be displayed.
In the K35x versions, the tare adjustment is stored when power is removed and is
re-used when next powered up.
This feature allows the operator to manually enter the tare weight.
After setting the preset tare value, indicator will display Pt followed by selected
preset tare value.
When a preset tare weight is being used the instrument will display Pt before
displaying the net weight.
Any printing of the tare weight will be followed by the letters Pt if a preset tare value
is active.
A long press of the <TARE> key will allow editing of the Preset Tare value. Press
the <OK> key to enter the Preset Tare setting. Change the Preset Tare setting
using the <SEL> and <EDT> keys.
The Preset Tare setting can be cleared by one of two means:
• Using a long press of the <TARE> key and editing the preset tare value to
zero.
• While the gross load is zero;
• Using a short press of the <TARE> key to re-tare the instrument in the usual
manner.
• OR, Using a short press of the <ZERO> key to zero the instrument in the
usual manner.
In the K35x versions, the tare adjustment is stored when power is removed and is
re-used when next powered up.
This key is used to toggle the weight display between the Gross weight and the Net
weight (provided that a Tare has previously been acquired using the <TARE> key).
