2. Press the UNIT key until the display shows “%” to indicate percent weighing mode.
3. The display will show “100.00%” with the reference sample on the scale. You may now remove the
reference sample and add the unknown sample to determine its relative weight. Press UNIT to exit.
Note: The reference sample value is erased upon exiting Percent Weighing mode.
3.5. Calibrating The Balance
The balance may need to be calibrated in certain situations such as:
• Before weighing for the rst time
• After the balance has not been used for some time
• If the balance location has changed
• If ambient temperatures have changed greatly
1. Prepare the calibration weight (see pg. 4 for required calibration weights).
2. Clean the weighing pan and press TARE to re-zero the balance.
3. When the balance is stablized, press and hold the CAL button for 5 seconds.
4. The display will show “-CAL-”, then the required calibration weight will ash on the display.
5. Place the calibration weight onto the center of the platform and wait for the display to stop ashing.
6. You may now remove the weight. The scale will return to normal weighing mode
3.6. Linear Calibration
Linear calibration adjusts the balance at two or more points, rather than just one. To enter linear calibration,
follow these steps:
1. Prepare the calibration weights (see pg. 4 for required calibration weights).
2. Clean the weighing pan and press TARE to re-zero the balance.
3. When the balance is stablized, press and hold the CAL button for 5 seconds.
4. The display will show “-CAL-”, then ash the rst required weight for span calibration.
5. At this point, press and hold the MODE button for 5 seconds. The display will ash the rst required
calibration weight for linear calibration.
6. Place the required weight onto the center of the platform.
7. When the display stops ashing, you may remove the weight.
8. Once the weight is removed, the next required weight for linear calibration will ash.
9. Repeat steps 6 and 7 until the display returns to zero when the weight is removed - indicating that linear
calibration is complete.
