12. CALIBRATION
• The GBK/GFK scales can be calibrated using kilogram weights or using
pounds weights, depending on the weighing unit selected at the time of
calibration.
• To start the calibration, either get into the calibration section through
the Scale Settings (“FUnC 3”- see Section 13.3) or turn the scale off and
switch on again then press [Tare] during the self-test. Enter code
number 0000 and press [Tare]. This will take you directly to the
calibration section.
• The display will show "UnLoAd"
• Remove all weight from the platform and then press the [Tare] key
when the display is stable. After the Zero point is set, the display will
show “Ld xx”. Place the suggested calibration mass on the platform. It is
best to use a weight close to the full capacity of the scale. If the mass is
different from the displayed value, enter the value of the mass in whole
numbers. The kg or the lb symbol will be on to show the active unit.
• Press the [Tare] key when the stable indicator is on.
• The scale will calibrate to the mass. When complete, it will display
“PASS” and then either display “S8 CAL” (if entered the calibration
section through the Scale Settings as per section 13.3) or return to
normal weighing (if entered directly). Remove the calibration mass.
• If an error message “FAIL H” or “FAIL L” is shown, re-check the calibration
and repeat. If the error cannot be corrected contact your supplier.
