2 Calibration Procedure (CAL)
1. Turn scale on and allow the unit to acclimatize and stabilize for 1 minute.
2. Press and hold the [Light/Cal] key for approx. 3 seconds. Display will show [CAL]
and then the required calibration weight.
3. Gently place the correct calibration weight on the center on the weighing pan.
4. Wait until display shows [ F] then turn off.
In case [ E] is displayed instead of [ F], this indicates a calibration
procedure error, unstable or wrong calibration weight applied for calibration.
Turn the scale off and on again and repeat the procedure.
3 Internal Calibration Procedure
1. Remove two screws of the rear housing and open it.
2. Connect
J1
on the main board by soldering the pads together.
3. Place scale on a hard level surface. Turn scale on.
Display shall show the internal counts.
4. The internal counts shall fall in the range from
3 000
to
5 000
. In case out of this
range, connect
J8
left side or right side to increase or reduce the reading.
Connecting or disconnecting pads on
J5
,
J6
or
J7
can fine tune the reading.
5. Press [On/Zero/Off] key once. Display will show [CAL] and then the required calibration
weight. Place the corresponding calibration weight on the center of the weighing pan
and wait until display shows [ F] and then turn off.
6. Disconnect
J1
. Calibration completed.
7. Turn scale on and check the accuracy at different weight.
8. Install rear housing of the scale.
In case [CAL E] is display instead of [CAL F], this indicates a calibration procedure error
or wrong weight applied for calibration.
Turn the scale off and then on and repeat the procedure.
