SF/SG Series Operating Instructions

1. Zero Point Adjustment

The zero point is automatically adjusted when power is turned on. If the display shows a positive or negative weight, the scale must be re-zeroed.

How to re-zero:

Step 1: Assure that nothing is on the weighing pan.

Step 2: Press .

Step 3: The WEIGHT display should read:

NET

ZERO

0

ZERO

SG series SF series

0.000

NET ZERO

2. Tare Adjustment

When weighing with a container, it is necessary to TARE out the weight of the container in order to get an accurate price/weight reading.

How to operate TARE:

Step 1: Place an empty container (e.g., 100 g) on the weighing pan. The display reads “ 100 ”.

Step 2: Press .

Step 3: The WEIGHT display should read:

T

TARE

SG series

NET

ZERO

Step 4: When removing the container from the pan, the display reads “ -100 ”.

0.000

SF series

0.000

NET ZERO

Note:

When a TARE weight has been set, it is not possible to set a new TARE weight of a lower value by the procedures above. It is necessary to delete the previous TARE first, before entering a TARE of lower value.
