NA**1type digital voltmeter peak power frequency

Usage

NA**1 type digital voltmeter is peak power frequency for dc high voltage test, high voltage power frequency experiment and design measuring instrument. This instrument can be used to measure the positive and negative polarities dc voltage, ac voltage peak, peak/sine wave appropriate 2. This instrument all adopt the integrated circuit, stable performance and good reliability, high accuracy, easy to use, easy to carry.
