Service Switches
The Masterpro balances are equipped with a service mode; in this mode, both
the SETUP functions and the calibration/adjustment functions are expanded.
Note: Open the access switch (B) to calibrate/adjust the balance in the service
mode (with the PSION Server or SARTOCAS Service Program for PCs).
Access Switch
The access switch (B) and the BPI switch (A) are located under the cap on the
raer panel of the balance, under a protective cap on the right side. On veri-
fied balances, this protective cap is sealed.
On high-capacity LP balances (≥16 kg), the access switch is located on the
left, behind screw (217), and the BPI switch is behind the two-hole screw
(216); both screws are next to the DC power jack (212).
Activating the BPI Mode / Deactivating the Write Protection
You must activate the BPI mode / deactivate the write protection:
– to calibrate/adjust the balance with the PSION Server, or
– to replace the balance PCB.
– Turn on the balance.
– When 0.00 g is displayed (depending on the balance model) remove the
protective cap or the two-hole screw (216) and move the BPI switch (A).
– The display goes blank; the line for metrological data begins flashing.
Wait for this line to flash at least 3 times, and then return the BPI switch to
the original position.
– Wait for the display to return to the weighing mode.
– Turn the balance off and then turn it back on again.
– The balance is now ready to operate in the BPI mode (the write protection
on the EEPROM has been deactivated).
Note: When the balance is in the BPI mode, it is not possible to operate peripheral
devices that use the RS-232 protocol.
“Err30” is displayed when you press p.
Note: If the balance does not communicate with the service software in the BPI
mode, you must remove the display and control unit (see page 17,
“Removing the Display and Control Unit from the Weighing Cell”).

Activating the Service Mode
The LP balances are equipped with a service mode that enables expanded
calibration/adjustment functions. With these expanded functions, you do not
need to use the PSION Server or SARTOCAS Service Program for PCs to cali-
brate/adjust the balance.
The service mode only remains active until:
1. you press Mto exit the menu, or
2. cis pressed when the “Service CAL Selection” menu is displayed (see
the overview on page 9).
The weighing mode is active (0.00 g is displayed - depending on the balance
model)
– Enter the service password: 202122.
– Press M.
– The SETUP menu is displayed and an “S” is shown in the lower left corner.
– The service mode is now active.
– Press cto exit the SETUP menu; press qto activate the calibration/
adjustment menu.

Adjustment options in the service mode:
1. int. adjust * – Span adjustment with internal weight
2. def. ext.lin. – External linearization with default weight
3. ext. linear. – External linearization (enter weight value in the IN-
PUT mode)
4. reprotest * – Reproducibility test of the internal adjustment
5. det. int. wt. – Overwrite the internal calibration weight
6. det. ext. wt. – Determine and store the external weight (user-defined
weight)
7. disp. *10 – 10-fold increased display resolution; SuperRange

8. def. ext.adj. * – External span adjustment with default weight
9. auto ext.adj.* – External span adjustment with automatic recognition
of calibration weight
10. ext.adj. * – External span adjustment with stored (user-defined)
weight (entered in the INPUT mode)
Note: In most cases it is not necessary to use service software programs (PSION or
Sartocas) to adjust the LP balances, because all necessary adjustment func-
tions are accessible when the balance is in the service mode.
You only need to use the adjustment software if the current adjustment error is
greater than 2% or if multiple adjustment steps are necessary due to unfavor-
able ambient conditions.

Performing External Linearization
After defining the linearization weights, the linearization procedure can be
started.
Note: If linearization weights of sufficient accuracy are available (at least one digit
greater than the display accuracy), it is not necessary to define the lineariza-
tion weights (in the INPUT mode).
In this case, you can start linearization by selecting the “def. ext.lin.” menu
item.
The procedure is described below.
– Activate the service mode again (see page 11).
– Press q.
– Press v (several times) to select the “ext. linear” menu item, tare the
balance if necessary and press qto start the linearization routine.
– The first linearity weight is displayed.
Center the corresponding weight on the weighing pan.
Note: Depending on the menu code setting (under 1 10 X), either calibration/ad-
justment is performed automatically (code 1 10 1: calibrate, then auto-ad-
just), or the deviation from the last calibration is displayed, but no adjust-
ment is made until you press a key (code 1 10 2: calibrate, then manual
adjust).
– The deviation from the last adjustment is displayed.
– If the error exceeds the tolerance limits, either press qto make the corre-
sponding adjustment, or press cto cancel the adjustment procedure.
– The second linearity weight is displayed.
– Center the corresponding weight on the weighing pan and press qto
confirm.
– Repeat this procedure until all linearity weights have been adjusted.
