4.0 CALIBRATION
• Press the [ZERO] key and power up the scale using the on/off button.
• Release the [ZERO] key and the display will show “SPAN”. Make sure
the hook is empty unless you intend to use any chains, slings etc to hold
the calibration mass. Add any items such as these to the hook before
continuing.
• Press the [ZERO] button and the display will show “SET” then “00000”
when the reading at zero is stable. This completes the zero calibration
• Following zero calibration the value of the mass being used to calibrate
the scale should be entered. Use the [HOLD] button to increment the
right hand digit, and the [UNIT] button to move this digit to the left.
Proceed by entering a number for the next digit if required, until the
value of your chosen calibration weight is displayed correctly.
• Load this mass onto the hook and when the scale is stable press the
[ZERO] key. The display shows ‘HOLD’.
• After a few seconds, the calibration is complete and the scale returns to
normal weighing showing the value of the calibration mass as used.
