Warranty 

IMI instrumentation is warranted against defective material workmanship for 1 year unless otherwise expressly 

specified.  Damage to instruments caused by incorrect power or misapplication, is not covered by warranty.  

If 

there are any questions regarding power, intended application, or general usage, please consult with your local 

sales contact or distributor.  

Batteries or expendable hardware items are not covered by warranty. 

 

Service

NOT

 recommended and may 

void any warranty.  If factory service is required, return the instrumentation according to the “Return Procedure” 

stated below.  

A repair and/or replacement quotation will be provided prior to servicing at no charge.

  Before 

returning the unit, please consult a factory IMI applications engineer concerning the situation as certain problems 

can often be corrected with simple on-site procedures.
