SETUP AND CALIBRATION
Your 758 indicator has been thoroughly tested and calibrated before being shipped to you. If you
receive the indicator attached to a scale, calibration is not necessary. If the 758 is being
connected to a scale for the first time or recalibration is necessary for other reasons, proceed as
indicated.
Calibration of the 758 Weight Indicating Instrument is
accomplished entirely by the keypad. To enter the
setup and calibration mode, the calibration jumper (J1),
must be removed before turning on the indicator. To
gain access to the calibration jumper, first remove the
instrument from the gimbal mounting by removing the
two large knobs and sliding the enclosure from the
bracket. Remove the two (2) screws from the left end
cap (as viewed from the indicator front) and remove the
end cap.
Locate the calibration jumper J1 on the circuit board
and remove it. See Figure No. 7. With the calibration
jumper removed, press the ON / OFF key. The display
will show intint=. The 758 is now ready for setup and calibration.
During the setup and calibration process it will be necessary to enter operational parameters via
the 758's keyboard. Pressing the PRINT key will cause the data entered or displayed to be
retained and the 758 will advance to the next prompt. The cursor location is identified by the
blinking character and can be advanced to the right to the next position by pressing the UNITS
key. Pressing the ZERO key will change the blinking character to the next value.
Scale Interval
With the display showing int=int= press the UNITS key to show the current setting. Press the ZERO
key until the proper scale interval (1, 2 or 5) is displayed, then press the PRINT key to store the
displayed value and proceed to the next prompt.
Decimal Point Location
With the display showing dP=dP= press the UNITS key to show the current setting. Press the ZERO
key until the number corresponding to the desired decimal point position is displayed. Press the
PRINT key to store this setting and proceed to the next step.
0 = XXXXX 1 = XXXX.X 2 = XXX.XX 3 =X X.XXX
Scale Capacity
With the display showing CAP=CAP= press the UNITS key to show the current setting. Press the
ZERO key to enter the proper digit at the blinking location. Press the UNITS key to step to the
right and the next digit location. Repeat the process until all five (5) digits of the capacity have
been entered. Should you make a mistake and press the UNITS key with an incorrect digit
entered, it will be necessary to press the UNITS key until the blinking character returns to the
proper location, then use the ZERO key to enter the correct digit. After all digits have been
correctly entered, press the PRINT key to store the capacity and advance to the next step.
Weighing Units
With the display showing Unt=Unt= press the UNITS key to show the current setting. If the value
shown is acceptable, press the PRINT key again to save it, otherwise press the ZERO key to
enter the new weighing units and press the PRINT key to save the new setting.
1 = Pounds Only 4=Kilograms/Pounds
2 = Kilograms Only 5=Ounces Only
3 = Pounds/Kilograms 6=Grams Only
