SETUP AND CALIBRATION
Calibration of the 708 Weight Indicating Instrument
is accomplished by turning on the instrument with
the calibration switch set to the CAL position. The
calibration switch is mounted on the printed circuit
board and is behind the right-hand end cap (as
viewed from the indicator front) of the desktop
enclosure. See Figure No. 11 for location of the
switch. To gain access to the switch, first remove
the instrument from the gimbal mounting by
removing the two (2) large knobs and sliding the
enclosure from the bracket. Remove the top and
bottom screws from the end cap as shown.
Access to the calibration switch in the NEMA 4X enclosure is gained through the front cover of the
enclosure. Refer to Figure No. 9 for the location of the switch.
Once the calibration switch has been located, make certain the instrument is turned off, then set the
calibration switch to the CAL position. Press the ON key. When the display shows int= release the
calibration switch to the OPR (operation) position. The instrument is now ready for setup and
calibration.
NOTE! During the setup and calibration process it will be necessary to respond with
either a YES or NO to questions asked by the indicator. Pressing the 1 key will display a
YES response while pressing the 0 key is a NO response.
The membrane keyboard is not to be operated with pointed objects (pencils, pens,
fingernails, etc.). Damage to keyboard resulting from this practice will
NOT be covered
under warranty.
