・Power not supplied 
 
・Power specification is 

changed from the 

ordered specification. 
 
・Circuit protector is OFF. 

・CPU abnormal. 

・Confirm power supply voltage on Circuit protector terminal 

base. 

・Confirm the voltage on name plate of Transducer is the same 

as the supplied power. 

 If it is different, return us Transducer, then the power spec.

 If yes, power off and wipe them off with moist cloth. (See NOTE) 
・Remove sensor and confirm electrode. 
 If condensation on electrode, wipe off with a wet rag after 

power-OFF. (See NOTE) 

・Change measuring sensitivity or integration setting.
