BT84-Calibration Proceedure Push Buttons – Calibration Mode

Dead EXIT Set Digit Digit Zero CAL Weight Select Increment Calibration Sequence 1) Press the (Gross/Net) key and the (Units) key at the same time for 3 seconds with

switches SW4 and SW3 closed. Or with SW 3 Open, Close SW 4 to enter Cal. Display will now show CXXXXX with the “C” flashing, the “X”’s could be any number on initial calibration.

2) Remove all weight from scale and press the[ZERO] button. Indicator should now read [C 00].

3) Apply >10% of capacity in weight to scale platform. 4) Press [TARE] button. The display will now show [XXXXXX] with the “X”’s being a

digit 0-9. Press the units button to move the digit to the right and the print button to increment the digit. When you have the display reading the same as the amount of weight you put on the scale, press the [TARE] button again. The displayed weight will now be steady and the “C” will be flashing.

5) Take the weight off the scale and check zero. Then reapply the weight and make sure the meter reads correctly.

6) If everything is correct, press the (Gross/Net) key and you are finished calibrating the scale, or open SW 4. If the readings in step 5 are not correct, repeat steps2-5.

Audit Trail To View the audit trail hold the (G/N), (UNITS), and (PRINT) for 3 seconds. AU-C## = Calibration, Number range is 1 – 99 (Returns to 1 after 99) AU-P## = Configuration, Number range is 1 – 99 (Returns to 1 after 99) Push Buttons – Audit Trail

ignored.) ? Commands must be capital letters, lower case will not function. NOTE: CONTINUOUS TRANSMISSION If 1200 baud is selected with 10 updates/sec., there will be missed serial updates since the time of transmitting a 14 character string takes about 117 ms., select at least 2400 baud. Page 10

Extended LED Values and Display Messages To see extended LED Values, close SW1-1 and SW1-2 and press the[ZERO] button until you go past parameter 31. The extended values will be displayed with their corresponding LED. To step through these values press[ZERO] button. When finished turn off SW1-1 and SW1-2 and this will return you to normal weighing mode. LED’s
