 Model 380360 Version 1.7 September 2003 

Safety 

1.  Circuits under test must be de-energized and isolated before connections are made 

(except for voltage measurements). 

2.  Circuit connections must not be touched during a test. Use extreme caution when 

working near bare conductors and bus bars. Accidental contact with conductors could 
result in electrical shock. 

3.  Use caution when working near voltages above 60VDC or 30VACrms. 
4.  After insulation tests, capacitors must be discharged. 
5.  Test leads (including alligator clips) must be in good working order, clean and without 

broken or cracked insulation. 

6.  When servicing, use only specified replacement parts.
