13. PERCENT MODE (Pct)

This is the mode to display the weight value in percentage compared to a 100% reference mass and is used for target weighing or checking the sample variable.

Selecting the percent mode

1Set “Unit selection ( Unit )” parameter of the function table to pct (percent mode). For details, refer to “5-2 Changing the Unit”.

Storing the 100% reference mass

2Press the SAMPLE key to enter the 100% reference mass storing mode.

To return to the percent mode without storing the 100% reference mass, press the CAL key.

3Place a container on the weighing pan, if necessary. Press the RE-ZERO key to cancel the weight (tare). The balance displays 100 0 pct .

4Place the sample to be set as the 100% reference mass on the pan or in the container.

5Wait for the stabilization indicator to be displayed. Press the PRINT key to store the reference mass. The balance displays 10000. pct . (The reference mass stored, even if the AC adapter is removed, is maintained in non-volatile memory.)

Notes

If the balance judges that the mass of the sample is too light to be used as a reference, it displays lo . Do not use the sample.

The decimal point position depends on the 100% reference mass.

7Place a sample to be compared to the reference mass on the pan. The displayed percentage is based on the 100% reference mass.

While the stabilization indicator is on, pressing the PRINT key will output the weight value, using the RS-232C serial interface.

Note

Peripheral equipment, that is sold separately, such as a printer or a personal computer is required.
