Below, position
Weight A kg
refers to the switch position furthest away
from the test/data socket.
Weight A lb
refers to the switch position next to
Weight A kg
.
1.
NO calibration Jack is required for this version 5,6 and 7 UC321.
2.
Set the mode switch on the bottom of the UC321 to the position furthest
away from the test/data socket.

7.
To check the calibration type set the mode switch to the position furthest
away from the test/data socket and press the measure switch.
By default, scale is set to

:2 point, (0lb,350lb).
llll----3333
:3 point, (0lb,176.4lb(80kg),350lb).
Slide Mode switch to position furthest away from the test/data socket press
Measure Switch
repeatedly to show
“

momentarily, the display will show the temperature
at calibration; i.e. (
