Calibration
Preparing the Calibration
Standard weights are required for calibration (not supplied). A 200 gram or a 400 gram standard
can be used.
Warm up the SC600 for at least 30 minutes before starting the calibration.
IMPORTANT CALIBRATION NOTE:
Before calibrating the SC600 determine the expected weight measurements that will be
encountered during normal use. For expected weight measurements up to 200 grams please
perform a 200 gram calibration. For expected weights above 200 grams please calibrate to the
400 gram standard.
400 gram calibration:
1. After the SC600 is warmed up, gently place the 400 gram standard weight on the center of
the weight platform. If the weight display does not show exactly 400 grams then continue
with the procedure, otherwise calibration is not required and the procedure can end at
this point
2. Press the CAL button once and the display will show '200 grams'
3. Press the TARE button once and the display will show '400 grams'
4. Press the CAL button once again and the display value (400g) will flash six (6) times.
5. Calibration is now complete. Calibration data will be stored internally in non‐volatile
memory meaning that calibration data will be saved even when the SC600 is powered
OFF.
200 gram calibration:
1. After the SC600 is warmed up, gently place the 200 gram standard weight on the center of
the weight platform. If the weight display does not show exactly 200 grams then continue
with the procedure, otherwise calibration is not required and the procedure can end at
this point
2. Press the CAL button once and the display will show '200 grams'
3. Press the CAL button once again and the display value (200g) will flash six (6) times.
4. Calibration is now complete. Calibration data will be stored internally in non‐volatile
memory meaning that calibration data will be saved even when the SC600 is powered
OFF.
