7.4  SPARE PARTS ORDERS - ROUTINE OR EMERGENCY 

Requests for spare parts should be directed to "Service" at DynAmp, LLC during normal 
hours.  When contacting us, please present as much information as possible, such as the 
related equipment Model and Serial Numbers (available on the equipment tag); the 
required part name; its DynAmp, LLC item number (and other identifying or vendor 
number(s); and your time needs.  An approved Purchase Order Number should be given 
with your order. 

7.5  RECOMMENDED SPARE PARTS 

The following table lists the minimum recommended quantities* for spare parts for the LKP 
Metering Unit.  As spares are used, replacements should be ordered.  Since continuous 
operation of high-current measurement systems is usually critical, stocking spare parts 
should be given high priority. 

A single module “A” kept on hand (see part number below), can be used to replace either 
of the modules in the Metering Unit and guarantee quick, error free repair.  Note that a 
module “B” cannot be used to replace a module “A” but the reverse is true. 

The LKP Series Measuring Heads require special repair procedures and materials.  
However, the heads are very reliable and should require little or no repair over its service 
life.  Please refer to the nearest authorized DynAmp service center for information on 
repairs.
