A.2 Service Calibration
Valor 1000 offer a choice of two calibration methods: Span calibration and Linearity Calibration.
Attention: Do not disturb the balance during any calibration.
SPAN [
SPAN
]
Initiates a span calibration procedure using a span calibration weight equal to the full capacity of
the scale. Press
On/Off
to enter the SPAN calibration routine, or press
Tare
to proceed to a Lin
calibration.
When 0.000kg is shown, short press
On/Off
to capture the zero weight if the platform is empty.
When the full capacity of the scale is shown, place a weight equal to the capacity of the scale and
short press
On/Off
.
If the scale displays "
Cal-E
", one of the weights used to calibrate is wrong and the scale did not
complete calibration.
To exit calibration at any point, short press
Tare/Menu
.
LIN [
LIN
]
Initiates a linearity calibration procedure (zero, mid-point and span).
When performing a linearity calibration, the scale will prompt you for a zero weight -- the platform
without anything on it and weight display at zero -- a Midpoint weight equal or close to 50% of the
Span weight, and a Span weight equal to the full capacity of the scale.
When 0.000kg is shown, short press
On/Off
to capture the zero weight if the platform is empty.
When the half capacity of the scale is shown, place a weight on the pan according to the value
shown on the display and short press
On/Off
.
When the full capacity of the scale is shown, place a weight equal to the capacity of the scale and
short press
On/Off.
If the scale displays "
Cal-E
", one of the weights used to calibrate is wrong and the scale did not
complete calibration.
To exit calibration at any point, short press
Tare/Menu
.
