Level Adjusting
Place the scale on a table.
Check the water mark. If, bubble is not centre adjust
the leveling feet until reach centre. Check the level
when you change the location.
Charging Battery
To charge the battery insert the adaptor pin to jack, jack is locating rear side of
the scale. Adaptor simply plug into the mains power. The scale no needs to be
turned on.
The battery should be charged for 12 hours for full capacity.
In the LCD display has an battery indicator to indicate the status of battery
charging, When the scale is plugged into the mains power the internal battery
will be recharged. When turn on the indicator ,if the battery indicator is full then
the battery has a full charge. If it is half then the battery is nearly discharged
and empty indicates the battery should be charged.
Do not use any other type of power adaptor than the one supplied with the scale.
Verify that the AC power socket outlet is properly protected.
Note: Please charge the battery before using the scale for the first time

Installation
Place the scale on a table..
Connect the adaptor pin in to the scale adaptor jack. Adaptor jack is locating,
rear side of the scale.
Adaptor connects into your AC power socket. Pluggable equipment must be
installed near an easily accessible socket outlet with a protective ground/
earth contact.
Turn on the On/Off key. If you want to turn off, press the key again.
Display will be show the version number and will be starting self checking.
After self checking, display will be come to normal weighing mode.
Warm-up time of 15 minutes stabilizes the measured values after
switching on.
Calibrate with exact calibration weights, minimum 1/3 of the scale capacity want
to use for calibration. For calibration, see details in parameter.
Then you can start your operation

6. OPERATION
Initial Start-up
Warm-up time of 15 minutes stabilizes the measured values after switching on.
6.1 Power ON/OFF
Switch on the scale by pressing . The display is switched on and the self
test is started.
If you want to switch off press the key again.
6.2 Zero
Environmental conditions can lead to the balance exactly zero in spite
of the pan not taking any strain. However, you can set the display of
your balance to zero any time by pressing key and therefore
ensure that the weighing starts at zero.
6.3 Tare
The weight of any container can be tared by pressing button so that with
subsequent weighing the net weight of the object being weighed is always
displayed.
Load weight on the pan.
Press key. Zero is displayed, and tare is subtracted.
Remove weight from the platform. Tared weight is displayed. It can
set only one tare value. It can display with a minus value.
Press key. Zero is displayed, tare weight is cleared.
6.4 Weighing Unit
Press key in the weighing mode to change the
Weighing unit: g / ct

6.5 Percent Weighing
The scale can set a sample weight to be shown as 100%. Then any other
weights place on the scale, it will be displayed as a percentage of the original
sample.
For example:
350g weight place on the scale and follow by press the key is pressed the
display will show 100.00%.
Remove the weight, and ensure display is zero
Place 300g weight on the platform, display will be show 85.71 % as per the
percentage of 350g (100%)
The weighing may be amended on the basis of greater numbers of samples,
improves the accuracy of percentage large quantities.

then will be show the total saved value. These displays will be shown only three
seconds. If the optional RS-232 interface is installed the weight data will be
send to printer.
Remove the weight from the pan.
When display get zero and stable then place the second weight.
It can continue until the memory gets fully.
6.7.1 Memory Recall
To recall the memory press key.
Display will be show
(X: Total number of accumulation) then will be show the total saved value. These
displays will be shown only three seconds.
