5.2 Cleaning
Clean the instrument and probes regularly depending on usage. The method is as follows:
① Use a soft cloth to wipe dust from the instrument and probe exteriors. When cleaning the LCD
screen, be careful not to scratch the transparent plastic protective cover.
② Use a soft cloth dampened with water to clean the instrument. Make sure to disconnect the power.
For more thorough cleaning, 75% isopropyl alcohol solution can be used.
Note:
① To avoid damage to the instrument or probes' surfaces, do not use any abrasive agents or chemical
cleaners.
② Before reconnecting power, ensure the instrument is completely dry to prevent electrical short
circuits or personal injury.
