Autel MaxiSYS MSOAK Oscilloscope Accessory Kit

Autel MaxiSYS MSOAK is a professional oscilloscope accessory kit designed to expand the electrical diagnostic capabilities of compatible Autel MaxiSYS diagnostic systems and the MaxiScope MP408 oscilloscope.

The kit includes two AC/DC current clamps with different measurement ranges, a Coil-on-Plug ignition probe, high-tension extension leads, and battery clips. These accessories enable technicians to measure both low and high current, analyze ignition signals, and perform more advanced electrical diagnostics on vehicle systems.

MSOAK is particularly suitable for workshops using the oscilloscope functionality of the MaxiFlash VCMI / VCMI2 or the standalone Autel MP408 4-channel oscilloscope.

Features

• 65 A AC/DC Current Clamp — Designed for accurate measurement of low and medium current without opening the circuit.
• 650 A AC/DC Current Clamp — Measures high current in systems such as starting and charging circuits.
• Coil-on-Plug Probe — Measures ignition coil signals directly without disconnecting the coil.
• HT Extension Leads — Enables easier secondary ignition waveform measurements.
• Battery Clips — Provides secure electrical connections to batteries and vehicle circuits.
• Oscilloscope diagnostics — Suitable for voltage, current, ignition, and other automotive waveform analysis.
• Non-invasive current measurement — Current clamps measure current without electrically connecting directly to the conductor.
• Professional workshop use — Designed for advanced automotive electrical diagnostics and troubleshooting.
• Carrying case included — Keeps all accessories organized and protected.

65 A AC/DC Current Clamp

The 65 A current clamp is particularly useful for measuring lower-current circuits and rapidly changing current signals.

Applications may include:

• Fuel injectors
• Fuel pumps
• Small electric motors
• Solenoids
• Parasitic current analysis
• Sensor and actuator circuits
• Other low-current electrical circuits

The clamp measures up to 65 A AC/DC and supports frequencies up to approximately 20 kHz.

650 A AC/DC Current Clamp

The 650 A current clamp enables measurement of high current without opening the circuit.

Applications may include:

• Starter motor current draw
• Alternator output
• Relative Compression testing
• High-current electric motors
• Vehicle main power circuits
• Other high-current systems

The clamp measures up to 650 A AC/DC.

Ignition system diagnostics

The included Coil-on-Plug Probe and HT extension leads enable secondary ignition waveform analysis with an oscilloscope.

They can be used to examine:

• Ignition coil operation
• Firing voltage
• Burn voltage
• Spark duration
• Differences between cylinders
• Causes of ignition misfires

Applications

MSOAK is suitable for:

• Automotive electrical diagnostics
• Starting system analysis
• Charging system analysis
• Relative Compression testing
• Ignition system diagnostics
• Current consumption measurements
• Electric motor and actuator testing
• Oscilloscope waveform comparison
• Advanced electrical troubleshooting

Compatibility

MSOAK is compatible with:

• Autel MaxiSYS Ultra S2 / MSUltra S2
• Autel MaxiSYS MS919 S2
• Autel MaxiSYS Ultra / MSUltra
• Autel MaxiSYS MS919
• Autel MaxiScope MP408
• Autel MaxiScope MP608

With the MSUltra and MS919 series, the MSOAK accessories are used with the oscilloscope functionality integrated into the supplied MaxiFlash VCMI / VCMI2.

MaxiScope MP408 is sold separately.

Package contents

• 65 A AC/DC Current Clamp
• 650 A AC/DC Current Clamp
• Coil-on-Plug Probe
• HT Extension Lead, 2 pcs
• Battery Clip, 2 pcs
• Blow-molded carrying case

Please note

• MSOAK is an oscilloscope accessory kit and is not a standalone measurement device.
• A compatible MaxiFlash VCMI / VCMI2 oscilloscope or Autel MaxiScope MP408 is required.
• Always select the correct current clamp and measurement range for the circuit being tested.
• A current clamp must be placed around a single conductor for correct current measurement.
• Appropriate high-voltage safety procedures must be followed when testing ignition systems.
