3.3.5 User Calibration
User calibration is used when it is desired to calibrate the balance using a mass of known value. User calibration limits
are no less than the 1/2 nominal capacity point and no more than the display over limit. For example, on a 210g
balance, it's no less than 100.00g and no more than 210.09g. To use this calibration feature, proceed as follows:
(FLASHING)
• Clear the pan.
• Press the Setup button, CAL is displayed.
• Press Enter button, CAL TYP is displayed.
• Press Enter button.
• Press and scroll to select USER calibration,
CAL TYP USEr is displayed.
• Press Enter button, the display indicates the last
calibration mass value which was entered with the
first digit flashing. (Sample illustrates 200g).
• Press to change value of digit and
button to advance to next digit. Enter the desired
mass value for your balance. This number must be
at least 50% of the full span value.
• After entering value, press Enter button, BUSY is
displayed.
NOTE: If a weight is left on the pan, the balance will
display CLR PAN (remove the weight from the pan).
The balance automatically resumes calibration.
• Display changes to PUT WT 200 g.
• Place specified calibration mass on pan.
• Press Enter button, BUSY is displayed. After a
few seconds CAL SET is displayed, the display then
