• This is a DC voltage tester with smart over-voltage protection and warning
  for vehicle repair.
• As electrical system for vehicle becomes more complex, the tester is able
  to test voltage value, identify DC polarity from different background light color,
  positive / negative sign, and over-voltage level indication.
• Moreover, the special designed probe is able to help user to hook, piercing,
  and probing the wires.
• Check on 6, 12, 24 and 48V systems.
• Wire Hooker and Piercing.
• DC Voltage Measurement.
• LCD with Dual Color Polarity indication.
• AC / DC identification.
• Data Hold.
• Low Power Consumption.
• Computer Safe.
• Over-Voltage Protection and Warning for 4 different voltage level.
• Use in ICEV, HEV and PHEV vehicles.
• The tester is not only for traditional vehicles, it is also suitable for HEV (Hybrid
  Electric Vehicles) and PHEV (Plug-in Hybrid Electric Vehicles). As for this kind
  of vehicles, it will generally has two batteries, one is 12 ~ 24V, and the other is
  42 ~ 48V. This kind of vehicle will have two voltage supply system, one is
  supplied by 12 ~ 24V battery, and another one is supplied by 42 ~ 48V battery.
  In general, 42 ~ 48V will eventually converted to voltage higher than 200V for
  the driver motor. With the over voltage protection indication, user is able to
  recognize which battery line they are measuring. In addition, some vehicle has
  DC/AC voltage converter to convert 12V battery to 110 ~ 240VAC. With this
  tester, user is able to make sure they are wiring with the correct DC wire.

• Systems 6~48V Systems.
• DC voltage Measurement 3.0 ~ 60.0V DC.
• Accuracy ± (1%+0.3)V.    
• Battery CR2032 3V X 1 pc.
• Working Environment 0 ~ 50°C (32 ~ 122°F) < 85%RH.
• Storage Environment -10 ~ 60°C (14 ~ 140°F) < 85%RH.
• Over-Voltage Warning.
• If measured voltage is about 70 ~ 100V, “OL0” will show on the LCD,
  please stop the measurement.
• If measured voltage is about 100 ~ 200V, “OL1” will show on the LCD,
  please stop the measurement.
• If measured voltage is about 200 ~ 300V, “OL2” will show on the LCD,
  please stop the measurement.
• If measured voltage is greater than 300V, “OL3” will show on the LCD,
  please stop the measurement.
• The voltage greater than 300V may damage the tester, please make sure the
  tester is not damaged before next measurement.
• WARNING: If any of the below Over-Voltage Warning shows on the LCD, it
  means the tester is connecting with the voltage out of specified, it may damage
  the tester and cause hazard to the user; please stop the measurement and
  remove the tester immediately.
