OUTLINE
Thank you for purchasing YP series electronic balance. The YP models are high performance electronic
balances that we confidently recommend based on 20 years of precision balance manufacture. While there
models are of course capable of fast and accurate weighing, the YP models all work on high precision strain
gauge load cell which implements high speed stabilization and high reliability. The YP series balances also
feature operation keys, improving operating convenience and making the balances easier to use.
These balances also feature a variety of other functions that make it more convenient for
customers to use for their own applications, including the Window Direct communication function,
which enables measuring results to be transferred to a PC without installing any software.
To ensure that you can make full use of the performance and function of your YP series balances,
read this instruction manual carefully and use the balance correctly in accordance with the
directions in the manual. When you have finished reading the manual, keep it in a safe place
together with the balance so that you can refer to it at any time.
YP-S series precision balance work on high precision strain gauge load cell which implements
high speed stabilization and high reliability.

Unpacking and delivery inspection
Check that all of the items indicated below are included in the package, and that nothing has been
damaged.
1. Main Body.
2. Pan.
3. Introduction Manual.
4. Adapter.
Turning the power on
1. Insert the plug of the Power Cord into the DC IN connector on the back of the balance.
2. Connect the Power Cord to the power outlet.
3. Press “ON”.
The display will automatically go through the changes indicated below.
Warming up
Before performing span calibration on the balance or measuring its accuracy, you must ensure
that is it in a stable state.
When stabilizing the balance, it is important that its temperature is stable.
Putting the balance in weighing mode and leave it with the power on for at least half an hour in
advance of calibration.
This is called “warming up”.
Using the balance
1. Enter the weighing mode.
2. Place a container on the pan.
3. Once the display has stabilized, press “zero/tare”.
3.1. The indication changes to zero.
4. Insert the sample into the container.
5. When the display has stabilized, (the stability mark) lights up, read the display.

PERFORMING SPAN CALIBRATION
Always perform span calibration for a balance after moving it. Weights are required for external
calibration balances.
Before performing span calibration, warm up the balance in advance.
Also, carry out the adjustment at a location where there are few people moving around and there
is no air flow or vibration.
1. Press “CAL”.
The weight value will flash.
The calibration record is being output. When the output has finished, span calibration will start
automatically.
2. Place the calibration weight on the pan.
Wait until the flashing weight value display changes to a steady 500.00.
3. Take the weight off the pan.
“0.00” will be displayed and the balance will return to the weighing mode.
