Er 05 

bAd.c or Er 05 (on 7 
segment display) 

Bad cell code. 
Check the cell code in the 
Diagnostics menu with known 
good loadbar connected to one 
indicator connector and then 
the other. 

Check the cell code in the Diagnostics 
menu for each load bar on its own and 
with both. See 

Accessing the hidden 

menus

 on page 34. Compare with valid 

cell codes for standard Tru-Test and 
competitor load bars and cell codes 
that need span calibration.  Refer to 
the technical bulletin 

Cell Codes.  

See 

Troubleshooting 

on page 13. 

Er 06 

Test Weight > 
Capacity! 

The test weight is larger than 
the capacity. 

Was the entered Capacity incorrect? 
Otherwise, use a smaller test weight. 

Er 07 

Test Weight < 1/3 
Capacity! 

The test weight is less than 1/3 
of the Capacity. For maximum 
accuracy, use a larger test 
weight. 

This is only a warning message. If a 
larger test weight cannot be used, the 
span calibration can still be completed, 
but with reduced accuracy. 

Er 08 

Test Weight too small.  The test weight is too small for 

an accurate calibration. 

A larger test weight must to be used. 
We recommend using a test weight 
that weighs approximately the same as 
a typical animal being weighed. 

Er 09 

Can't get good 
reading. 

Can't get good reading. 

Use a static weight. 

Er 10 

The Test Weight is 
overloading the scale. 

The load bar output signal is 
overloading the input of the 
scale indicator. 

Use a much smaller test weight. 

Er 11 

The load cell output 
signal is reversed. 

The load cell wiring may be 
reversed or the load cell may 
be mounted upside-down. 

Correct any load cell mounting or 
wiring issue. If this doesn’t work, return 
the indicator to Tru-Test Limited. 

Er 12 

No test load placed 
on the platform. 

No test load placed on the 
platform. 

Check mV/V response to loads in the 
Diagnostic menu.  See 

Accessing the 

hidden menus

 on page 34. Correct any 

shorted wiring. 

Er 13 

The load cell has a 
large no load negative 
offset. 

The load cell has a large no 
load negative offset. 

Replace load bars. 

Er 14 

Reset caused by 
watchdog. 

The processor crashed due to 
electrical supply trauma or 
brown-out or software fault. 

If problem persists, return to Tru-Test 
Limited for analysis.
