* Avoid lengthy exposure to extreme heat or cold, your scale works best when operated and stored at normal room
temperature. Allow the unit to acclimate to any major temperature change for at least one hour before use.
*Place the item to be weighed on the platform, after the stable weight is displayed remove the item immediately.
This will prolong the longevity and accuracy of this weighing instrument..
.** Do not operate near an in-use cell phone, cordless phone, radio, computer or other electronic device. These
devices emit RF and can cause unstable scale readings. If your scale ever performs poorly, try moving the scale to
a different room or location. This is a very precise scale - the display may seem to wander or jump when weighing.
This is due to air currents or vibrations. Stable weighing is achieved when the display remains fixed for 3 seconds.
OPERATION_____________________________________________
If your scale ever performs slowly, inaccurately, or shows the battery icon please replace the batteries.
Battery Operation:
1) Two “AAA” size Heavy Duty or Alkaline batteries are required.
2) To install batteries:
a) Release the battery cover by sliding the locks in-wards.
b) Place batteries into battery compartment aligned correctly.
c) Replace battery cover and lock it.
DO NOT USE EXCESSIVE FORCE AND DO NOT PRESS ON THE TRAY
3) The scale is now ready for battery operation.
*Remove the batteries if you plan to store the scale for longer then 14 days
CALIBRATION__________________________________________
Important: Always perform calibration procedure after first turning the unit on and allowing it to warm up and
stabilize for 20 seconds. If possible please calibrate the scale on your SCALEPAD (included in the box), mousepad
or similar surface. Calibrate your scale at regular intervals if the scale is subject to weather or altitude changes or if
the display shows Out2. Incorrect calibration can occur if you do not follow the steps exactly. If your scale does not
perform accurately, please also try replacing your batteries. You will need a 100 gram weight (or 200 gram for the
550) to calibrate this scale.
NOTE: if you do not have access to a calibration weight you can purchase one at your local store or in emergency
situations you can use coins or weights (ie 20 US Nickels = 100g) as a calibration weight.
Calibration Procedure:
1) Turn the scale OFF and Place the it on a Flat, very stable surface
(Be certain the scale is OFF)
2) Press and hold both the “CAL” and “ON/OFF” keys for 5 seconds, the display will show 2ERO and then 100.0 (or
200)
3) Gently place the correct calibration weight on the tray and wait 3 seconds.
4) Press the ON/OFF key. The display will show CAL and then PASS,
calibration is complete. Gently remove the weight and turn the scale Off.
NOTE: if after calibration your scale does not read accurately, this indicates calibration error and the calibration
process should be repeated more slowly. Please calibrate on your scalepad, mousepad or similar surface if
possible.
FEATURES____________________________________________
* Power Up Segment Test: When first turning the unit on, all segments of the display will appear as shown below.
This display will remain for approximately 3 seconds and then reset to zero. The display may also change
brightness during this time and show a blank screen for a moment before 0.0 appears
