* The digital zero function sets a desired measurement point as zero and displays the
deviation from this zero point. When weighing a load, it can be used as the tare, etc.
* The zero value is saved in non-volatile memory (EEPROM) and is maintained even
if the power is disconnected.
* To change the zero adjustment operation, use the function (
Cf-11
) .
To protect against accidental operation, press the + keys or press and
hold the key for more than 1 second to turn the digital zero function on.
4.4. Operation mode
- Upper / lower limit setting mode
Use this mode to set the upper and lower limit values of the comparator.
- Calibration mode
Use this mode to perform zero and span calibration with an actual load (calibration
weight).
- Function mode
Use this mode for setting functions.
- Check mode
Use this mode to confirm input and output operation.
