If when weighing in air the weighing unit starts to flash a message of “ADD”, this
informs you that the weight of the sample may not be enough to give accurate
calculations and therefore it is recommended that a larger sample weight is used.
At this point the USER can add more weight to the lid until the flashing stops which
signifies that the minimum sample weight required has been met.
Once the flashing stops remove the sample from the lid of the chamber, press the
[Unit/Clr]
key and make sure the display shows zero, place the sample back onto
the lid to start the process again.
Minimum sample weights are as follows:
HCB J302 – 5g
HCB J1002 – 10g
HCB J2002 – 20g
* Please note that if extra weight is not added to meet the minimum sample weight
requirements when the message “ADD” is being displayed, the balance will continue
to calculate based on the sample weight at that time.

DISPLAY
DENSITY
Press the
[Density]
key to display the density of the sample, ie- “14.2 den”
Press the
[Density]
key a second time to display the Karat value for the sample. For
example if gold with silver is selected the display would show “ 14
KAg
”. Like wise
for other display options the display might show “ 14
KCu
” for gold with copper, “ 14
K11
” for gold with silver and copper in a 1:1 ratio, “ 14
KMn
” for a ratio other than 1:1
and “ 14
K o
” for other density of alloys that might be used. See section 6.2 for
details of setting the alloy options.
Press the
[Density]
key a third time to display the content of gold determined during
the test, ie- “583 Cnt”.
If the density value is outside of the expected range (see table opposite), the karat
value and content value will not be displayed. Only the density value will be
available.
