2.6 Initial Calibration

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

5.2 Calibration

PR 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, press the Tare / Menu-Cal button and select InCal 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 Cal 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:

To perform a Calibration Adjustment, select InCal Adjustment 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 r eading agrees with
the test mass.

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 refer to the specification tables in the "Span Calibration Points",
SPECIFICATIONS, Section 9.

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.

Steps for span calibration

Expected weight reading: 200.000g (Test mass value)
Actual weight reading: 200.014g
Difference in grams: – 0.014g
Difference in divisions: – 14 (InCal Adjust value)

Linearity calibration uses three calibration points, one at zero load and the others at specified loads.
With no load on the balance, 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.

When the balance is used in trade or a legally controlled application it must be set up, verified and sealed in
accordance with local weights and measures regulations. It is the responsibility of the purchaser to ensure that all

pertinent legal requirements are met.

6.1 Settings

Before verification and sealing, perform the following steps in order:

1. Verify that the menu settings meet the local weights and measures regulations.

2. Verify the units turned On meet the local weights and measures regulations.

3. Perform a calibration as explained in Section 5.2.

4. Set Approved Mode to On in the Balance Setup menu.

5. As shown in Figure 6-1, press the push button inside the hole.

Note: When Approved Mode is set to On, external calibration can’t be performed.

6.2 Verification

A weights and measures official or authorized service agent must perform the verification procedure.

6.3 Sealing

After the Balance has been verified, it must be sealed to prevent undetected access to the legally controlled
settings. Before sealing the device, ensure the Approved Mode setting in the Balance Setup menu has been set to
ON.

x If using a paper seal, place seals over the security switch and the bottom housing as shown.

x If using a wire seal, pass the sealing wire through the holes in the security screw and the bottom housing

as shown.

7.1 Connecting, configuring and Testing the Printer / Computer Interface

Use the built-in RS-232 Port to connect either to a computer or a printer.
If connecting to a computer, use HyperTerminal or similar software like SPDC
described below.
(Find HyperTerminal under Accessories/Communications in Windows XP.)

Connect to the computer with a standard (straight-through) serial cable.
Choose New Connection, “connect using” COM1 (or available COM port).
Select Baud=9600; Parity=8 None; Stop=1; Handshaking=None. Click OK.
Choose Properties/Settings, then ASCII Setup. Check boxes as illustrated:

(Send line ends…; Echo typed characters…; Wrap lines…)
Use RS232 Interface Commands (Section 9.6.1) to control the balance from a PC.

SPDC Software
The Serial Port Data Collection / SPDC software is provided by Ohaus and can be used on operating systems that

do not have the HyperTerminal software mentioned above. SPDC software can preliminarily collect and transfer
the data to Microsoft files (such as Excel, Word, etc.).

Choose the export file type and export file path and then press Run as shown below.

Important notice for verified weighing instruments in the EU

When the instrument is used in trade or a legally controlled application it must be set up, verified and sealed in
accordance with local weights and measures regulations. It is the responsibility of the purchaser to ensure that all
pertinent legal requirements are met.

Weighing Instruments verified at the place of manufacture bear the following supplementary metrology marking on
the descriptive plate.

Weighing Instruments to be verified in two stages have no supplementary metrology marking on the descriptive
plate. The second stage of conformity assessment must be carried out by the applicable weights and measures
authorities.

If national regulations limit the validity period of the verification, the user of the weighing instrument must strictly
observe the re-verification period and inform the weights and measures authorities.

As verification requirements vary by jurisdiction, the purchaser should contact their local weights and measures
office if they are not familiar with the requirements.
