6. General Function
6.1. Zero function
Use to correct drifted zero value when the scale is unloaded, and motion is not detected.
This function works when ZERO KEY is pressed, and the ZERO LAMP is on.

6.2. Setting Tare Weight Function

Press the TARE KEY. Then, the scale will memorize the weight of the tare and will display
zero value “0”kg. The TARE LAMP will be on.
To escape this function, remove everything from the scale, and press the TARE KEY.
Then, the TARE LAMP will be off and this function is terminated.

6.3. Hold Function

This function will only work with IR remote control.
Also, F08 of CCB setting mode must be set to 4.

■ Automatic hold
- Press * KEY when the scale is empty (Initial zero state).
- The weight display will indicate . HOLD LAMP is on.
- After loading a thing, if the weight turns stable then, a display shows and
average weight will appear.
- The weight of a loaded thing is displayed.
- To escape the automatic hold mode, when zero point is on, press * KEY.
Then, the message of is displayed and HOLD LAMP is off and normal weighing
mode is reverted.

■ Manual hold
- Press * KEY loading a thing.
- This message of is displayed and sequentially the message of is
shown with appearing the average weight.
- The weight of a loaded thing is displayed.
- To escape the manual hold mode, remove everything from a hook, or press the * KEY.
Then, HOLD LAMP will be off and the scale changes from a hold mode to a normal mode.

When a thing is over-weighed within the maximum weight value, the error message
is displayed.
Do not weigh the thing whose the limit of a maximum weight value is exceeded.
If a load cell is broken, then the load cell has to be replaced.

Something wrong in a Load cell connection or in an A/D conversion.

Please contact us to resolve this technical problem.
