Warranty 

 

IMI instrumentation is warranted against defective material and 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 and other expendable hardware items are not covered by 

warranty. 

 

Service 

 

Because of the sophisticated nature of IMI instrumentation, field repair is typically 

NOT

 recommended and may 

void any warranty.  If factory service is required, re

turn 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. 

 

Return procedure 

 

To expedite returned instrumentation, contact a factory IMI applications engineer for a RETURN MATERIAL 

AUTHORIZATION (RMA) NUMBER.

  Please have information available such as model and serial number.  Also, 

to insure efficient service,
