TROUBLESHOOTING AND HELPFUL TIPS

The POSTSHIP

®

 has been designed to be highly robust and give years of reliable and 

accurate use. 

NEVER

 overloaded, drop or shock the scale as inside all digital scales 

are delicate load cells which measure the weight of an item. They are easily and can 
sometimes be permanently damaged so it’s important that if scales are to be shipped or 
moved anywhere they are packed very well and handled carefully.

The most common reasons for malfunctioning scales and inaccuracy are faulty AC 
adapters, low batteries or bad battery connections. If a problem is found whilst using an 
AC adapter, it is recommended to test using batteries. It is also recommended to change 
batteries on a regular basis.

NEVER

 use an AC adapter at the same time as having batteries installed.

Digital scales always perform slowly and to some extent inaccurately when cold (under 
15°C/59°F) or if they are too hot (over 30°C/86°F), so it’s recommended to operate at 
normal room temperatures of 19-30°C (66-86°F). The operating temperature range of this 
model is 0-40°C (32-104°F).

1.  If the scale does not seem to be accurate, or display shows 

Err-C

, recalibrate as 

described on Pg 9.

2.  MEASURED WEIGHT DOES NOT STAY STILL AND CONSTANTLY CHANGES 

UP

OR 

DOWN

:

This is usually caused by a faulty AC adapter. Please test unit using a good quality  

set of batteries to see if this makes a difference. If it does make a difference a new AC  

adapter can be sent under warranty by contacting your supplier.

3.  THE BACKLIGHT OF THE DISPLAY CONSTANTLY FLASHES 

ON

 AND 

OFF

:

This is usually caused by a faulty AC adapter. Please test unit using a good quality  

set of batteries to see if this makes a difference. If it does make a difference a new AC  

adapter can be sent under warranty by contacting your supplier.

4.  THE DISPLAY IS PERMANENTLY SHOWING ON 

EEEEE

This indicates the scale was dropped, shocked or somehow damaged and the delicate  

load cells have been damaged. Try recalibrating as described on Pg 9. If this does not  

resolve the problem contact your supplier.

5.  THE DISPLAY SHOWS 

Err-0

:

The scale has been overloaded. Ensure that you have not placed a total or combined  

weight (including when using 

ZERO

 or 

TARE)

 in excess of the scales maximum 

capacity.

6.  THE DISPLAY SHOWS 

UNST

 OR FLASHES 

Err-S

:

This indicates that the scale is not on a level stable surface. Reposition the scale and  

ensure that there is nothing jamming or stuck between the scale body and platform.  

If this does not resolve the problem contact your supplier as the load cells maybe  

fatally damaged.
