Deleting (resetting) previous calibrations

•Press and hold the “PT” button for around 18 seconds -The display remains empty until calibration mode is accessed . -The indicator shows the value of the first calibration point, and the lowest indication bar (left side of the display) flashes. •The three previous programmed values can be checked on the screen by moving the indication bar up or down using the up and down button. -When the lowest indication bar lights up, the first (lowest) value is displayed, and above this bar are the second and third bars showing the highest value. -When calibrating just one point, the values for the next and the highest value should be zero. •Press and hold the “up” or “down” button until the middle calibration value is shown. -The middle indication bar flashes. •Press the “0/T” button. -The first segment flashes. •Use the “up” and “down” buttons to reset the flashing segment to zero. •Move to the next segment using the “0/T” button. •Reset all segments until the indication bar starts flashing. •Press and hold the “up” or “down” button until the highest calibration value is shown. -The highest indication bar flashes. •Repeat this process until all segments have been reset.

Single-point calibration

•Return to lowest value. -The indicator shows the value of the first calibration point, while the lowest indication bar flashes. •Place a load of a known weight on the scale and specify the weight on the indicator by briefly pressing the “0/T” button. -The first segment starts to flash. •Use the “up” and “down” buttons to change all segments, and confirm the value of each segment using the “0/T” button until the correct weight has been entered. -The bottom indication bar will begin flashing again once each segment has been corrected. •Confirm the entered weight by pressing and holding the “0/T” button for 3 seconds. -The display now counts down from AF 08 to AF 00, at which point the first calibration point has been set. •You can exit calibration mode by pressing the “up” or “down” button until AP XX appears. -This figure indicates calibration sensitivity as a percentage, e.g. AP 07. •Press the “0/T” button until the reading in the display disappears.

Multipoint calibration

•Press and hold the “PT” button for around 18 seconds -The display remains empty until calibration mode is accessed . -The indicator shows the value of the first calibration point, while the lowest indication bar flashes. •Place a load of a known weight on the scale and specify the weight on the indicator by briefly pressing the “0/T” button. -The first segment starts to flash. •Use the “up” and “down” buttons to change all segments, and confirm the value of each segment using the “0/T” button until the correct weight has been entered. -The bottom indication bar will begin flashing again once each segment has been corrected. •Confirm the entered weight by pressing and holding the “0/T” button for 3 seconds. -The display now counts down from AF 08 to AF 00, at which point the first calibration point has been set. •Press the “up” button. -The middle indication bar starts flashing while the indicator displays the value of the second calibration point.

•Place a load of a known weight, larger than before, on the scale and specify the weight on the indicator according to the explanations above. -The second calibration point is registered once you confirm it. •Repeat this procedure for the third calibration point. •You can exit calibration mode by pressing the “up” or “down” button until AP XX appears. -This figure indicates calibration sensitivity as a percentage, e.g. AP 07. •Press the “0/T” button until the reading in the display disappears. The indicator switches automatically to a small weight graduation once calibration is complete. The selected weight graduation is activated once the indicator has been switched off and then switched on again.
