3.1 Turn on the power. Open the switch. The displaying windows displays from "F----
1"to "F----9" and after a certain time for stabilizing, "
for 15 minutes. Instability of the displaying at every beginning is normal; after a
certain time, the displaying will stabilize.
3.2 With empty scale platform, the displaying deviates from zero, pressing "TARE" key,
then the displaying will return to zero.
3.3 If the scale has not been used for a long time or just bought, the scale should be
calibrated. Firstly, the scale is fully preheated (over 15 min.) with empty scale
platform. Then press "CAL", the displaying window shows "CXXX" and the balance
will automatic calibrate (XXX should be the weight of standard weights). At the same
time, only place calibrating weights on the scale platform. After stabilizing, the scale
displays the weight of the calibrating weights and the unit is "g"; till now the
calibration is completed and the scale can be normally used. If press "CAL", but
display "C----F", which indicates the Zero point is not stable. Then re-press "TARE"
to make "zero" point stable; and re-press the "CAL" to carry out calibration.
If weight of a weighed article exceeding the scale measuring range, the scale will
warn"F----H".
3.4 If needing to tare, first place the container on the platform, after stabilizing, press
"TARE" ;the scale displays "zero". Then place the article in container, at this time, it
shows the net weight of the article. Remove the article and the container. The scale
shows a negative value of container weight. Still press "TARE" to return to "zero"
3.5 Count
3.5.1 First choose samples. To precisely count the articles, firstly the quantity of
samples for counting should be chosen in according with the weights of the
articles. The quantity of samples can be chosen from "1-10-20-50-100". For a
small number of articles, the larger quantity of samples, the more precise.
3.5.2 Place the samples on the pan, the balance will show the total weights of samples.
Then press "Count", balance will show "1", and unit will show "pcs", which
indicates that balance is now counting. And all the samples are one unit. Then
press "Count", the displaying will show between 1-10-20-50-100. The quantity
of articles and samples must be the same, and place the similar articles. The total
amount of objects is showed. Press the "Count" again back to the normal
situation.
3.6 The units can be changed between "g", "ct", "ozt", "oz", "GN", "dwt", "lb". Press
"Units" to change the units during weighting.
3.7 Data Output
Balance is targeting data output interface RS232C and can be directly connected to the
printer. 6 feet and 8 feet of RS232C can connect to an external print button or to
computer. The following soft wares are needed, when connects to computer:
3.7.1 Transmission format: serial asynchronous
