soldered at each soldering point as shown on the right.
1.1.4. Insert power cord from A/C adapter into Jack on PCB.
1.1.5. Pass the load cell wire through the path in rubber shield block.
1.1.6. Put the shield sheet and the kid in its position.
3.2. Start–up
•Specification data and weight calibration are required for proper operation.
1. Press [ON/OFF] key to turn on the scale.
The software version number is displayed. Ex. Ver.0.04. all segments count
up, the display blanks, then shows all 8’s.
•If “Lo-Vol is displayed , this indicates that the input voltage is too low to operate
the scale. The input drop detection circuit is equipped to prevent the unit from
mal-functioning when the voltage drops.
To exit this error, reset the scale by turning off and on.

3.7.Weight Calibration (SPAN Adjustment)
Before performing calibration procedure check the following:
A. Decimal Point Position according to capacity weight - - (SPEC-05 BIT1-0)
B. LOAD CELL Output Sensitivity - - - - - - - - - - - - - - - - - (SPEC-04 BIT 3-0)
C. The DS-160 has an Animal mode (SPEC 11 BIT 0), if this spec is set to “1”
= effective, then calibration is locked out. To perform the calibration set
spec to ”0” = inhibit and reset it when calibration is complete.
D. Minimum Display required - - - - - - - - - - - - - - - - - - - - (1 or 2 or 5)
E. The DS-160 pole must be mounted to the base before performing
calibration.
Note: Frame grounding of the load cell requires the unit to be
assembled before calibration, it will not weigh correctly if it is
assembled after calibration.
Next is the adjusting procedure

!ZERO Lamp!sign will light when the current zero point is within _d
of true zero and true zero.
!TARE Lamp!sign will light when tare weight is set.
!STABLE Lamp!sign will light when weight / scale is in stable condition.
4.2. ZERO Resetting
Place some weight on the platform. (example 1lb)
4.2.1. Press [RE-ZERO] key. Zero re-setting will be performed.

to 0.00. If the weight is out of range, the display will lock up with all 8’s.
4.3. One Touch Tare Reduction
4.4.1 Place tare weight on platform. (example: 1lb.)
4.4.2 Press [ T ] key.
4.4.3 If the weight is within the available range of tare reduction, the display will return to 0.00
and the tare “!”lamp will light up. If it is out of range, the weight will remain in the display.
