Overview of the User / Service SETUP Program

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”).
