3  Test prods and replacement

1. Types of Test prods

MODEL8072:Standard Test prod

Used for ordinary measurement.

(Attached  to  the  Line  probe  at  the  time  of

purchase.)

MODEL8017:Extension probe

Used  in difficult-to-reach situations.

MODEL8016:Pickle prod (Optional)

Used to hook the probe on a conductor.

2. How to replace Test prod

To  remove  the  Test  prod,  turn  the  cap  of  LINE  probe

counterclockwise.  Insert  the  threaded  end  of  another  prod

into  the  hexagonal  hole  on  the  probe  cap  as  shown.  Then,

turn the probe cap clockwise to secure it on the body of the

probe.

When the instrument and the test lead are combined and used 

together, whichever lower category either of them belongs to will be 

applied.
