Unload the pan and dose the weighing chamber. lf necessary,
re level the balance using the level indicator as a guide.

Internal Calibration:

The internal calibration weight conforms to accuracy class E of
1
the International Organization of Legal Metrology (OIML).
Select the weighing range of 0 to 1500 mg (both LEDs next
to the Symbols " ~ 750 mg" and " ~ 1500 mg" go out).
Press the CAL key (13). "CAL" will now be displayed below the
weight readout.
Remove both Substitution weights. "L" is now displayed on the
balance. Afterwards, place the weights back on the pan. The
weight readout is displayed again.
Zero the display and press the CAL key (13) again when the
display shows a zero readout. The weight display now
indicates "C."
lf "CE" is displayed instead, zero the display and press the
CAL key again.
After a few seconds, "CC" will be displayed followed by 0.000
mg. An acoustic Signal indicates the end of the calibration pro-
cedure.
Important Note!
While calibration is in progress, indicated by "C" or "CC" in the
display, do not press any key.
However, should you do so by mistake, just turn the balance off,
then on again with the ON/OFF key. Following this, repeat cali-
bration.
