2. INSTALLATION
2.1 Unpacking
Carefully remove your PXP 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 Adventurer 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 / 0.00001 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 PXP 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

PXP 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 PXP 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 PXP balance is first installed, or when it is moved to another location, it must be calibrated to ensure
accurate weighing results. PXP 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.

PXP Series Balance EN-15
5.2 Calibration
PXP balances offer a choice of three calibration methods: Internal Calibration (for InCal models only), Span
calibration and Linearity Calibration.
Attention: Do not disturb the balance during any calibration.
5.2.1 Calibration Sub-menu (InCal models)
Note: ExCal models only have Span Calibration and Linearity Calibration.
5.2.2 Internal Calibration (not applicable to ExCal models)
Calibration is accomplished with the internal calibration mass. Internal Calibration can be performed at any time,
provided the balance has warmed up to operating temperature and is level.
With the Balance turned ON and no load on the pan, the internal calibration can be performed.
Alternatively, press the Tare / Menu-Cal button and select Internal Cal to initiate the internal calibration.
The screen shows the status, and then press any button to return to the current application after calibration.
5.2.3 InCal Adjust (not applicable to ExCal models)
Use this calibration method to fine tune the effect of the Internal Calibration.
Calibration Adjust may be used to adjust the result of the Internal Calibration by +100 divisions.
Note: Before making a calibration adjustment, perform an Internal Calibration. To verify whether an adjustment is
needed, place a test mass equal to the span calibration value on the pan and note the difference (in divisions)
between the nominal mass value and the actual balance reading. If the difference is within +/- division, calibration
adjustment is not required. If the difference exceeds +/-1 division, calibration adjustment is recommended.
Example: Expected weight reading: 200.000 (Test mass value)
Actual weight reading: 200.014
Difference in gram: – 0.014
Difference in division: – 14 (InCal Adjust value)
To perform a Calibration Adjustment, select InCal Adjust from the list of Calibration Menu; enter the value (positive
or negative divisions) to match the difference noted earlier in the procedure.
Recalibrate using Internal Calibration. After calibration, place the test mass on the pan and verify that the mass
value now matches the displayed value. If not, repeat the procedure until Internal Calibration reading agrees with
the test mass.
Once completed, the balance stores the Adjustment value and the display returns to the current application.
5.2.4 Span Calibration
Span calibration uses two calibration points, one at zero load and the other at specified full load (span). For
detailed calibration mass information, please see the specification tables in section 9.1.
With the balance turned On and no load on the pan, Span Calibration can be performed. The best accuracy is
achieved using the mass closest to the full span value.

EN-16 PXP Series Balance
Steps for span calibration
1. Press and hold the Tare / Menu-Cal button, and the
Calibration Menu will display.
2. Press Yes to enter the Calibration Menu. To change
the calibration mode, press No
until Span Cal (span
calibration) is displayed.
3. Press Yes to begin the span calibration.
4. Calibration masses value will be shown in the screen.
5.
After the display shows "Place weights" and "100.0000
g", place weight(s
) of 100 g on the pan for calibration.
To change to the calibration point of half full capacity
(e.g. 50 g), press the Function / Mode button.
6.
After the screen shows "Place weights" and "50.0000
g", place weight(s) of 50 g on the pan for calibration.
7. Remove the weight(s) from the pan.

PXP Series Balance EN-17
8. Once the span calibration is completed successfully,
"Calibration done" will display.
Press any button to return to the previous screen.
5.2.5 Linearity Calibration
Linearity calibration uses three calibration points, one at zero load and the others at specified loads.
For detailed calibration mass information, please see the specification tables in section 9.1.
With no load on the scale, press Linearity Calibration to begin the process.
The balance captures the zero point, and then prompts for the next weight.
Continue to follow the instructions on the display until the calibration is completed.
Steps for linearity calibration
1. Press and hold the Tare / Menu-Cal button, and the
Calibration Menu will display.
2. Press Yes to enter the Calibration Menu. To change
the calibration mode, press No
until Linearity Cal
(linearity calibration) is displayed.
3. Press Yes to begin the linearity calibration.

EN-18 PXP Series Balance
4. Calibration masses value will be shown in the screen.
After the di
splay shows "Place weights" and "50.0000
g", place weight(s)
of 50 g on the pan for calibration.
5. Remove the weight(s) of 50 g from the pan. After a
while, "100.0000 g" will display. Place weight(s) of
100
g on the pan for calibration.
6. Once the linearity calibration is completed successfully,
"Linearity done" will display.
Press any button to return to the previous screen.
