5 Battery clamps cable
To supply power to the Scopebox through connection to
vehicle's battery.
6 20:1 Attenuator
It allows the Scopebox to measure fuel injector and primary
ignition waveforms.
*Note: Please note this attenuator should be not used for
any high voltage measurements other than fuel injectors and
primary ignition.
7 Secondary ignition pick-up
BNC Connector
Crocodile Clip
High-voltage Clip
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.
