摘　　要：指针式测厚仪属于接触式测量仪器,接触压力和接触形式影响测量精度,在做电线电缆哑铃试片厚度测量时,要选择合适的测量头和接触压力,否则会造成较大的测量误差。The accuracy of the dial thickness gauge, a contact type measuring device, is determined by the measuring pressure and the way of contact. Appropriate measuring head and measuring pressure shall be used to measure the dumbbell specimen otherwise large measurement errors may arise.
