1. INTRODUCTION
1.1 Inspection

Examine the shipping carton for any sign of damage. Inspect the 
unit and any accessories for damage. If there is any damage then 
consult your distributor immediately.

1.2 Description

The PC15250 is designed to quickly and simply prove the presence 
of all three phases on a distribution system and indicate the phase 
sequence.

It is ideal for identifying worn or unmarked cables or ensuring 
motors etc. are wired with the correct phase sequence.
The retractable GS38 probe shields give a choice between longer 
exposed tips for reaching inaccessible contacts and safer, shorter 
lengths for increased safety.
