Service Information 

 
The MegaPulse D5-PF tester is warranted to the original purchaser for a period of 1 year.  This warranty does not 
cover problems due to misuse or neglect.  Malfunctions which occur within the limits of the warranty will be corrected 
at no charge.  Mail the instrument postpaid to the manufacturer.  Dated proof of purchase is required for all in-warranty 
repairs.  The manufacturer is also available for calibration and / or repair of instruments that are beyond their warranty 
period.  Contact the manufacturer for a cost quotation.  Ship the instrument and your remittance per the instructions 
given by the manufacturer. 
 

 

General Maintenance 

 

To  avoid  contaminating  the  PWB  with  oil  from  your  fingers,  handle  it  by  the  edges  or  wear  gloves.    If  the  PWB 
becomes contaminated, refer to the cleaning procedures given later in this section 

 

 

Cleaning 

 

CAUTION 

Do  not  use  aromatic  hydrocarbons  or  chlorinated  solvents  for  cleaning.    These  solutions  will  react with the 
plastic materials used in the instrument. 

 
Clean the front panel and case with a mild solution of detergent and a damp sponge. Clean dust from the PWB with 
clean, dry, low pressure (<20 psi). 
 

 

Calibration Information 

 
The  MegaPulse  D5-PF  has  been  fully  calibrated  at  the  factory  in  accordance  to  our  published  specifications.  It  is 
recommended that you have this instrument re-calibrated and safety check done at least once per year. The procedure 
consists on internal components tolerance verification and calibrating the meter reading to agree with the capacitor 
bank.  
 
The Calibration procedure must be performed by qualified personnel. Contact Compliance West USA for the latest 
calibration procedure.  Have ready the serial number of the MegaPulse D5-PF tester.
