CALIBRATION INSTRUCTIONS
THIS SCALE IS ACCURATE WITHIN 0.1g, only calibrate if your readings are inaccurate beyond 0.1g. Allow
your scale to warm up for several seconds before calibration. Always move your hands very gently
during calibration as to not cause vibrations or air movement.
1. PLACE THE SCALE ON A FLAT SURFACE THAT HAS NO VIBRATIONS AND MAKE SURE THERE IS
ABSOLUTELY NO AIR MOVEMENT. (SURFACE MUST BE EXTREMELY STABLE).
2. TURN THE SCALE OFF AND CLEAR THE PLATFORM (MAKE SURE NOTHING IS ON THE PLATFORM NOT
EVEN THE PLASTIC TRAY).
3. TURN THE SCALE ON BY PRESSING .
4. WHEN THE DISPLAY SHOWS 0.0, WAIT 5 SECONDS AND THEN PLACE A 100 GRAM WEIGHT ON THE
CENTER OF THE PLATFORM.
5. WAIT FOR THE DISPLAY TO STABILIZE, THEN PRESS AND HOLD THE MODE KEY FOR 10 SECONDS. THE
DISPLAY WILL FLASH 100.0 TWICE, (THIS WILL TAKE ABOUT 7 SECONDS, CONTINUE TO HOLD THE KEY
FOR AN EXTRA COUPLE OF SECONDS AFTER IT HAS STOPPED FLASHING)
6. RELEASE THE MODE KEY AND REMOVE THE WEIGHT FROM THE PLATFORM. CALIBRATION IS
COMPLETE
IF THE READINGS ARE INACCURATE, PERFORM CALIBRATION AGAIN. IF YOUR SCALE WILL NOT
PROPERLY CALIBRATE OR SHOWS “ERR” PLEASE VISIT OUR WEBSITE FOR ADVANCED CALIBRATION &
TROUBLESHOOTING INSTRUCTIONS
BATTERY INSTRUCTIONS
USE TWO AAA BATTERIES. PLEASE MAKE SURE THE POLARITY IS CORRECT WHEN INSTALLING NEW
BATTERIES. LOW BATTERIES ARE THE #1 CAUSE OF SCALE MALFUCTION SO BE SURE YOUR BATTERIES
ARE GOOD.
ADVANCED STABILITY FEATURE (ASF)
This scale has a stability indicator, the letter “S” in the top left corner of the screen. Whenever the letter
“S” is displayed that means the displayed weight is stable.
TOOLS
