4) Press and Hold the 

 key until the cal-weight reading flashes on the screen (ie 200.00 

for PS7-200/300. 500.0 for 

PS7-700/800/1000). 

Then release. 

5) The display will show "PASS". Calibration is complete. After a few seconds, the scale will 
return to normal weighing mode. Remove the weight from the tray. 
 
If the displays shows "FAIL",  please recalibrate the scale again. 

NOTE:

 If after calibration your scale does not read accurately, this indicates calibration error 

and the calibration process should be repeated more slowly. Otherwise check online for a 
possible updated calibration instruction. 

Please recalibrate on a very stable flat surface!

INACCURACY/ERROR/DAMAGE

The primary reasons for inaccuracy or malfunction are low batteries, incorrect calibration. 
overload or operating on an unstable surface. Although the PALMSCALE is designed to be 
extremely durable with extra overload protection built into the case. It's 
 
important that you never overload or drop/shock the scale. Scales are delicate instruments and 
unlike Cellular phones, scales have delicate sensors that determine how much an item weighs. If 
you drop or shock your scale, these sensors "feel" the shock and are sometimes destroyed. This 
happens with all digital scales. We design our scales to be as resistant to shock or drops as 
possible, however there is no way 
 
for us to protect 1()()% against load cell or sensor damage. A well-treated scale will provide 
years of reliable and accurate weighing. However an abused scale will only work until its sensors 
are damaged. 

FEATURE

Power, Up Segment Tool

 
When first turning the unit on, all segments of the display will appear from "99999" to "00000", 
and all the indicators will light. 

Overload

When on applied load exceeds the capacity, 

 & "OVER LOAD" will appear on the 

display. Remove the excessive load immediately. The unit may return to normal operation.
