2.3.1 Initial Calibration
When the scale is operated for the first time, a zero and span calibration are recommended to ensure
accurate weighing results.
Before performing the calibration, be sure to have the appropriate calibration weights as listed in table
below. Ensure that the LFT switch/calibration lock is set to the unlocked position.
You can also adjust the GEO setting according to your location
.
For detailed GEO information, please check
the
Geo Code Adjustment
section below.

2.3.2 Zero Calibration
[
ZErO
]
Zero calibration uses one calibration point. The zero calibration point is established with no weight on the
scale. Use this calibration method to adjust for a different static load without affecting the span or linearity
calibration.
Calibration procedures:
1.
Long press the
Menu
button until you see
mM.E.N.U
.
2.
Release the button and wait for the display to show

button to establish the zero point.
5.
The display shows
--C--
, and then
-DONE-
when the Zero calibration is finished.
Note:
If zero calibration is failed or if after 40 seconds the calibration is still not successful,
CAL E
is
displayed for 3 seconds and the previous calibration data will be restored.
6.
Then the display shows
SPAN
. Press the
Exit
button to exit.
