Secondary 
ignition pick-up 
 
This  ignition  pick-up  is  applied  in  the  following 
situations:  Secondary-distributor  ignition  analysis, 
Secondary-simultaneous  ignition  analysis  and 
Secondary-direct ignition analysis. 
It has three ends: BNC connector (for connecting to 
CH1/CH2/CH3/CH4), crocodile clip (for Grounding) 
and high-voltage clip (for connecting high-voltage 
line), near which has an attenuator equipped for 
high-pressure attenuation to prevent the Scopebox 
from being impacted. 
*Notes: 
1). The high voltage clip should be clamped on the 
insulated lead (COP  Extension Cord, see Item 8) 
instead  of  on  the  spark  plug  to  prevent   
breakdown and electric shock.   
2).  Please  try  to  keep  an  instance  of  2  inch  from 
other high-voltage line to avoid the interference.
