INSTRUCTION MANUAL
FOR PRECISION BALANCE YP SERIES
Thank you for choosing our electronic balance.

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.

Choosing the Installation Site
The measuring performance of the balance is greatly influenced by the
environment where it is installed.
Observe the following points to ensure safe and accurate weighing.
Caution
Do not use the balance anywhere exposed to explosive, combustible or
corrosive gases.
This could cause fire or trouble.

6
Precautions on Use
Use the correct power supply and voltage with the balance.
Using an incorrect power supply or voltage with the balance will lead to fire or trouble with
the balance.
Note also that if the power supply or voltage is unstable or if the power supply capacity is
insufficient, it will not be possible to obtain satisfactory performance from the balance.
Avoid locations where the balance will be exposed to any of the following.
¤Air flow from an air conditioner, ventilator, door or window
¤Extreme temperature changes
¤Vibration from surroundings or nearby equipment

7
Unpacking and Delivery Inspection
Check that all of the items indicated below are included in the package, and
that nothing has been damaged.

[2] Pan
[3] Introduction Manual
[4]Adapter
¤Direct sunlight
¤Dust, electromagnetic waves or a magnetic field
Install the balance on a strong and stable flat table or floor.
Placing the balance in an unstable site could lead to injury or trouble with the balance.
When selecting the installation site, take into account the combined weight of the
balance and the item to be weighed.

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”.
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.

9
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

10
USING THE BALANCE
1 Enter the weighing mode
2 Place a container on the pan.
3 Once the display has stabilized, press “zero/tar”.
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.
Selecting the Display
Switching Units
You can display different units from among those set to be available.
1 press “UNIT” in the weighing mode.
Repeatedly pressing this key will cycle you through the registered units.
