Dual-Point with Zero (First Zero) Calibration
This is a standard calibration method requiring one weight, an empty scale, and has one
conversion factor.
This method uses two calibration points (
CAL1=
and
CAL2=
) to establish a zero (no load)
calibration value and to span the indicator. The two points correspond to zero weight and the
test load or test weight and can be applied in any order.
NOTE:
This method should be used for first-time calibration and complete recalibration.
CAL1=
– First Calibration Weight
1.
The display will show
CAL1=
. This is the first of two calibration weights. This weight
could be ZERO (NO LOAD) or the TEST WEIGHTS (TEST LOAD).
2.
Press the
TARE
key to view the current setting.
3.
If the first calibration weight is to be ZERO (NO LOAD), press the
TARE
key.
4.
If the first calibration weight is to be the TEST WEIGHTS (TEST LOAD), use the
UNITS/
and
Fn/
keys to input the value of the test weights.
5.
Place the weights on the scale platform, then press the
TARE
key.
6.
Starting at the left and proceeding right, a series of dashes will appear on the display.
7.
Next, starting at the left and proceeding right, the dashes will disappear, after which
the display will show:
CAL2=
.
CAL2=
– Second Calibration Weight
1.
The display will show
CAL2=
. This is the second of two calibration weights. This
weight could be ZERO (NO LOAD) or the TEST WEIGHTS (TEST LOAD).
2.
Press the
TARE
key to view the current setting.
3.
If the second calibration weight is to be ZERO (NO LOAD), press the
TARE
key.
4.
If the first calibration weight is to be the TEST WEIGHTS (TEST LOAD), use the
UNITS/
and
Fn/
keys to input the value of the test weights.
5.
Place the weights on the scale platform, then press the
TARE
key.
6.
Starting at the left and proceeding right, a series of dashes will appear on the display.
7.
Next, starting at the left and proceeding right, the dashes will disappear, after which
the display will show:
CAL3=
.
CAL3=
– Last Calibration Weight
1.
The display will show
CAL3=
. This weight is not used.
2.
Press the
UNITS/
