汽车检测仪器主要用来检测直流电流强度、直流电压、交流电压及导线的电阻等参数外，还可用来检测转速、闭合角、占空比（频宽比）、频率、压力、时间、电容、电感、半导体元件及温度等。
Vehicle testing instruments are mainly used to detect DC current intensity, DC voltage, AC voltage and conductor resistance. They can also be used to detect speed, closure angle, duty cycle (frequency-width ratio), frequency, pressure, time, capacitance, inductance, semiconductor components and temperature.
