1.4 Safety Precautions

CAUTION: Read all safety warnings before installing, making connections, or servicing this equipment.

Failure to comply with these warnings could result in personal

injury and/or property damage.

Retain all

instructions for future reference.

zVerify that the AC adapter’s input voltage range and plug type are compatible with the local AC main power

supply.

zMake sure that the power cord does not pose a potential obstacle or tripping hazard.

zDo not position the balance such that it is difficult to reach the power connection.

zThe balance is for indoor use only. Do not operate the equipment in hazardous or unstable environments.

zOperate the equipment only under ambient conditions specified in these instructions.

zDo not drop loads on the pan.

zUse the balance only in dry locations.

zDisconnect the equipment from the power supply when cleaning.

zUse only approved accessories and peripherals.

zService should only be performed by authorized personnel.

EN-4 PX Series Balance

2. INSTALLATION

2.1 Unpacking

Carefully remove your PX balance and each of its components from the package. The included components vary

depending on the balance model (see the list below). Save the packaging to ensure safe storage and transport.

Please read the manual completely before installing and using the PX balance to avoid incorrect operation.

Components included:

x Balance

x Power adapter + Attaching plug

x Stainless steel pan

x Pan support (for 0.1 g / 0.01 g model only)

x Warrenty card

2.2 Select the Location

Avoid heat sources, rapid temperature changes, air current or excessive vibrations. Allow sufficient space.

2.3 Leveling

Be sure the balance is level before it is used or after its location is changed.

The PX balance has a level bubble in a small round window beside the display.

To level the balance, adjust the 4 Leveling Feet until the bubble is centered in the circle.

Please refer to Figure 2-1 for leveling.

Figure 2-1. Leveling

PX Series Balance EN-5

2.4 Connecting Power and Acclimatising the Balance

Connect the DC output connector to the power receptacle on the rear of the balance. Then connect the AC adapter

plug to a suitable electrical outlet.

Acclimatising

It is suggested that the balance should not be used until it has been connected to power and acclimatised to the

environment for a certain period of time. In the case of a balance with the precision above 0.1 mg, the

acclimatisation time should be 1.5 hours; in the case of balance with the precision of 0.01 mg, the acclimatisation

time should be more than 4 hours.

2.5 Connecting the Interface

The PX balance has two data interfaces, RS232 and USB.

Use the RS

-232 port to connect either to a computer or a printer with a standard (straight-

through) serial cable.

Use the USB port to connect to a computer with a USB 2.0 Type A to Type B cable.

Note:

For Connecting, Configuring and Testing the Printer / Computer Interface, see the Printing section.

2.6 Initial Calibration

When the PX balance is first installed, or when it is moved to another location, it must be calibrated to ensure

accurate weighing results. PX balances are classified into two categories, InCal models and ExCal models. InCal

models have a built-in calibration mechanism which can calibrate the balance automatically and does not require

the use of external calibration masses. If preferred, InCal models can also be manually calibrated with external

masses. ExCal models are calibrated with external masses. Make sure to have the appropriate calibration masses

available before beginning calibration.

4.5 Density Determination

Note: Before using any application, be sure the balance has been leveled and calibrated.

Use this application to determine an object’s density.

A Density Determination Kit, Part Number 80253384, is designed to be used with PX series balances.

Illustrations in this procedure refer to the density kit, however, you may use whatever lab apparatus that will suit

the requirements for density measurements. A built in reference density table for water at temperatures between

10ºC and 30.9ºC is included in the balance software. Review this entire section before attempting density

measurements.

Operation Method

Press and hold the Function / Mode button until the Density appears on the screen.

After confirmation by pressing Yes, the message "Change parameter?" will display on the screen. The settings

can be kept or changed as desired.

Item Settings:

x Sample Type: Solid, Liquid

x Auxiliary Liquid: Water, Alcohol, Other

x Porous Material: Off, On

x Water Temperature: 20Ԩ (by default)

x Alcohol Temperature: 20Ԩ (by default)

Four types of density determination can be made:

1. Solid more density than the auxiliary liquid

2. Solid less density than the auxiliary liquid

3. Liquid density

4. Porous material (impregnated with oil)

The following are the operating procedures for determining density of solid, liquid and porous material with water

as the auxiliary liquid. Other auxiliary liquids are also applicable for density determination.

4.5.1 Measuring the Density of a Sinking Solid Using Water

Press and hold the Function / Mode button until Density

appears.

Press Yes to initiate the Density Determination.

Item Settings:
