compliant.It can identify the cause of your CHECK ENGINE and perhaps fix it
without going to see your dealer. It also assists you in easily passing annual e
missions tests and SMOG CHECK. It covers full OBDII/ EOBD diagnostic func
tions for engine system. O2 sensor test, EVAP systems test, and board monito
ring test give you full control of your vehicle's running status,while a graphical
and numeric live data stream display will help you to find out the faulty sensor
readings.
KW870 Battery Tester can test all automotive cranking lead acid battery,
including ordinary lead acid battery,AGM flat plate battery,AGM spiral battery,
and Gel battery,Lithium battery etc. it adopts the state-of-the -art conductance
testing technology in the word to easily, quickly and accurately measur e the
actual cold cranking amps capability of the vehicle starting battery,healthy
state of the battery itself,and common fault of the vehicle starting system and
charging system, which can help maintenance personnel to find the find the
problem quickly and accurately,thus to achieve quick vehicle repair.
It Support multi-languages,customer can select different language which

CUR: Current Voltage
MAX: Maximum Voltage during Ignition MIN: Minimum Voltageduring
Ignition
The waveform will stay in staticuntil there's changes in the voltage
changesdetected
Various vehicle voltage analyses
• Discharge Voltage: When the ignition OFF,engine OFF (Over 20
Minutes),the Discharge Voltage should be around 12V. If the discharge
voltage is lower than 11V, it will be hard to turn the ignition ON. If the
discharge voltage continuously stay under 11V, ii means the battery is
aging and replacement is needed.
• Starting Voltage: During ignition, the voltage will drop to a certain
point, at this minimum point is Starting Voltage (Around 7.5- 9.5V). If
the Starting Voltage continuously stay under 7.5, it means battery
capacity is low and needs to be replaced
• Charging Voltage: When the ignition ON,engine ON. The alternator
will continuously charge the car battery,normally is around 14V
