3.1
Turn on the power
.
O pen the switch
.
T he displaying windows displays from “ F----
1 ” to “ F----9 ” and after a certain time for stabilizing, “ 0·0” appears; T hen preheat s
for 15 minutes
.
Instability of the display ing at every beginning is normal; after a
certain time, the display ing will stabilize.
3.2
W ith empty scale platform, the displaying deviates from zero, pressing “ TARE ” key ,
then the display ing will return to zero.
3.3
I f 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
.
T hen press “ CAL ” , the displaying window show s “ CXX X ” and the balance
will auto matic calibrat e (XXX should be the weight of standard weight s )
.
A t the same
time, only place calibrating weight s on the scale platform
.
A fter stabilizing, the scale
displays the weight of the calibrating weight s 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 indicat es 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 ”
.
T hen place the article in container , at this time, it
shows the net weight of the article
.
R emove the article and the container. T he scale
show s a negative value of container weight
.
S till press “ TARE ” to return to “ zero ”
3.5
Count
3.5.1 F irst choose samples.
To
precisely count the articles , firstly the quantity of
samples for counting should be chosen in accord ing 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. A nd all the samples are one unit. Then
press “ Count ” , the displaying w ill show between 1-10-20-50-100
.
The quantity
of articles and samples must be the same, and place the similar articles. T he 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.

Data Output
B alance 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. T he following soft wares are needed, when connects to computer:
3.7.1 Transmission format: serial asynchronous
3.7.2 Serial communication protocol: Baud rat:600, data units: 8 units, starting unit:
1 unit, ending unit: 1unit
