SETUP AND CALIBRATION
Your 220 indicator has been thoroughly tested and
calibrated before being shipped to you. If you
received the indicator attached to a scale,
calibration is not necessary. If the indicator is
being connected to a scale for the first time or
recalibration is necessary for other reasons,
proceed as indicated.
The calibration switch is located on the enclosure
rear panel. You may gain access to this switch
simply by removing the calibration switch access
screw on the rear panel. Refer to Figure No. 8.
Figure No. 8
During the setup and calibration process it is necessary to enter operational parameters via the
220's keypad. Pressing the
ENTER
key without
entering a new value will retain the current
setting and advance the 220 to the next prompt. To change a setting, enter a new value and
press the
ENTER
key. This will save the new value and advance the 220 to the next prompt.
Pressing the
ASTERISK
key will "backup" to the previous prompt or return to normal operation.
CAUTION: The membrane keypad is not to be operated with pointed objects
(pencils, pens, fingernails, etc). Damage to keypad resulting from this practice will
NOT be covered under warranty.

calibration switch access hole on the rear panel. Press and release the calibration switch. The
