**SPECIAL WARNING**
Cell-Phones, Cordless-Phones, and any radio-frequency device can cause temporary interference and cause the
scale to temporarily not work properly. Please do not use any electronic device near the scale. Just like in an
Airplane, do not use your cell-phone near the scale when it is in use. While there is NO risk of permanent damage
to the scale, interference can cause an incorrect calibration or incorrect weight readings.
CALIBRATION
When to calibrate - calibration is almost never required.
If the scale is inaccurate, calibration may be desired when the scale is first set up for use, or if the scale is moved to
a different altitude or gravitation. This is necessary because the weight of a mass in one location is not necessarily
the same in another location. Also, with time and use, mechanical deviations can occur.
How to calibrate
**The UL-30 requires a 10kg calibration weight to calibrate. The UL-50 requires a 20kg calibration weight. (you
can use a combination of weights such as 5 2kg weights)**
1. The scale must be powered OFF. Press and hold [ZERO] first, then Press [ON/OFF] while keeping the
[ZERO] button depressed, then release both keys. The display will show the A/D value (a series of random
numbers).
2.Wait for the stable A/D value to be displayed, Press [UNIT] the display will show "0SAVE", then the display
will return to the random A/D value.
3.Place the 10kg (UL-30) or 20kg (UL-50 weight(s) on platform. Wait for the stable A/D value to display, then
press [UNIT], the display will show "0SAVE". Calibration is complete, remove the weight(s).
4.Turn the scale OFF (Press the ON/OFF key) , then turn it back ON and check some weight readings. If
calibration is still incorrect, repeat calibration but try it more slowly.
If calibration is repeatedly incorrect then: 1) Replace the batteries, 2) Try a more stable surface or vibration and
