Сервисный рабочий процесс
Fit, Cover and Compare Both Plugs
Place The Spark Plug
Place the spark plug into tester socket A or B. Use both sockets when you need side-by-side comparison testing.
Close The Protective Cover
Cover the transparent protective cover before testing to help keep the operator safer during spark observation.
Connect Power And Start
Plug the power adapter into the side power interface, connect power, and turn the rotary switch clockwise to power on the tester.
Adjust RPM And Observe
Continue turning the switch clockwise to adjust simulated RPM. Observe spark plug status through the protective cover.
Plug-And-Play Operation
Place the spark plug, close the cover, connect power, adjust the switch, and observe the spark condition through the cover.
Безопасное использование
Keep the Cover Closed During High Voltage
Close The Protective Cover
Always close the transparent protective cover before testing. The tester is designed for observation through the cover, not open-cover operation.
Предупреждение о высоком напряжении
Up to 1000V voltage may be generated during testing. Do not touch the spark plug, socket, or exposed test area while the tester is powered.
Выключите питание перед использованием
Do not insert or remove a spark plug while the power supply is connected. Turn off the tester first, then place or remove the spark plug.
Use The Correct Adapter
Use a compatible power adapter. The manual specifies 100-240V AC input and 12V 1A DC output for the SPT101 tester.
Supported Spark Plugs
SPT101 is suitable for most 12V gasoline vehicle and motorcycle spark plugs. Confirm fitment before testing unusual or non-standard spark plugs.
Dry Storage Recommended
Store the tester in a dry place when not in use. Avoid hot, humid, non-ventilated, or corrosive environments.
Compare the Spark Results
Compare both removed spark plugs in air under the same setting, then confirm any suspected ignition fault with the vehicle procedure.

Spark Plug Fit and Comparison Questions
Что AUTOOL SPT101 Used For?
SPT101 compares the visible spark behavior of two removed plugs in air at the same adjustable firing-rate setting. Confirm suspected faults under the applicable vehicle procedure.
Which Spark Plugs Can SPT101 Test?
SPT101 is suitable for most 12V gasoline vehicle and motorcycle spark plugs. For unusual, modified, or non-standard spark plugs, confirm fitment before testing.
How Do I Use The SPT101 Spark Plug Tester?
Place the spark plug in tester socket A or B, close the protective cover, plug the adapter into the side power interface, connect power, turn the rotary switch clockwise, adjust the simulated RPM, and observe the spark condition through the cover.
Can SPT101 Test Two Spark Plugs At The Same Time?
Yes. SPT101 supports dual-hole simultaneous testing, which lets you compare two spark plugs side by side and observe differences in spark strength more efficiently.
What Is The Working Frequency Range?
The tester’s control is marked with a simulated speed up to 6000 rpm. Treat this as the bench firing-rate setting and compare plugs at the same position; it is not the engine’s real speed or load.
What Power Supply Does SPT101 Need?
The SPT101 manual specifies a power adapter input of 100-240V AC and output of 12V 1A DC. Use a compatible adapter and confirm the plug type for your region before ordering.
Is SPT101 Safe To Use?
Use it carefully. Up to 1000V voltage may be generated during testing. Always close the protective cover before testing, do not touch the spark plug or test socket during operation, and power off the tester before inserting or removing spark plugs.
Can I Insert Or Remove Spark Plugs While Power Is Connected?
No. Do not pull out or insert the spark plug while the power supply is connected. Turn off the power first, then insert or remove the spark plug.
Что входит в комплект?
Package contents: SPT101 main unit, retail box, user manual, and power adapter. Plug type or adapter version may vary by selected option or destination.
What Is The Difference Between SPT101, SPT105, SPT301, And SPT360?
- SPT101 is a compact dual-hole model with rotary RPM adjustment.
- SPT105 adds adjustable test hole height.
- SPT301 uses three-hole comparative testing with a digital display.
- SPT360 uses five-hole comparative testing with a digital display for users who need to compare more plugs at once.
How Should I Maintain And Store SPT101?
Check connected parts regularly and tighten loose parts in time. Avoid rough surface wear, corrosive liquids, hot or humid storage, and non-ventilated storage areas. Keep the circuit and wires in safe condition and replace aging wires when needed.
