15-1 Error message

 

 

In case of error display, please take measure accordingly with the countermeasures. 

 

Error display 

Cause

 

Countermeasure

 

 

Key lock function is operated.  

Conduct key lock cancellation with the use of 
14-1 KEY Lock cancellation method.  

 

1. Dead weight value is small. 
2. Voltage of span calibration 

conducted point is either same or 
lower than zero point.  

3. There is no change in load cell 

output or change upon small dead 
weight value.  

This error is occurred under calibration status. 
Calibration shall be conducted using appropriate 
dead weight.  
Check the disconnection of load cell since (-) 
output of load cell is conducted.  

 

 

 
Load cell output value is high.  

This error is occurred when checking load cell 
output voltage of check mode.  
Abnormality of load cell shall be checked since 
load cell output is 35mV or higher.  
It shall be less than 15mV or lower in general. 

 

 

 
Load cell output value is low.  

This error is occurred when checking load cell 
output voltage of check mode.  
Abnormality of load cell shall be checked since 
load cell output is -35mV or lower. 

 
 

 
It exceeded max range of display value.

It exceeded max range of display that is either -
199999 or 999999. 
Conduct calibration again after checking load cell 
output voltage and disconnection.  

 

 

15-2  Load cell inspection

 

 

When the load cell in use is instable, following items shall be inspected.  

 

1.

 

Check whether or not load cell terminal is properly connected to the meter.  

2.

 

Check whether or not terminal connection within Summing Box and Junction Box is properly 

conducted. 

3.

 

Check whether or not there is mechanical interference.  

4.

 

When the zero point value of load cell, namely output value under no load status of load cell, 

strays  off  from  self-specification  range,  it  may  be  caused  by  mechanical  transformation  by 
overloading and impact, interference of meter container and structure, damage in inner circuit 
of load cell, etc.   

5.

 

Check  whether  or  not  measured  resistance  between  terminals  of  load  cell  conforms  to  the 

specification (refer to catalogue and report).  

6.

 

Measure the insulation resistance between each lead wire (wire in red, white, green, and blue) 

and earth wire with 50V D.C insulation tester and check whether or not it is higher than 100 ㏁.
