Safety requirements EN Installation (Overvoltage) Class This product is powered by a main power supply conforming to Installation (overvoltage) Class II. Warning: Ensure that no overvoltage (such as voltage caused by lightning) reaches the product. Otherwise, the operator may suffer electric shocks. Installation (overvoltage) class definition Class I refers to the signal level, which is applicable to the measuring terminal of the instrument connected to the source circuit. Measures have been taken to limit the instantaneous voltage to the corresponding low level. Class II refers to the local distribution level, which is applicable to instruments connected to the mains (AC) supply.
Pollution level Level 2 Pollution level definition ⚫ Level 1: No pollution, or only dry non-conductive pollution. This pollution level has ⚫ Level 2: Generally, only dry non-conductive pollution. Temporary conduction due to no impact. For example: clean room or air-conditioned office environment. condensation may sometimes occur. For example: general indoor environment. ⚫ Level 3: Conductive pollution, or dry non-conductive pollution becoming conductive due to condensation. For example, an outdoor environment with a canopy. ⚫ Level 4: Permanent conductive pollution through conductive dust, rain, or snow. For example: outdoor places.
Security level Level 1 - Grounded products 1.5 Maintenance and cleaning Maintenance: Do not make the LCD exposed to direct sunlight for a long time when placing the oscilloscope. Cleaning: Regularly check the oscilloscope and probe according to the requirements of the operating conditions, please follow the following steps to clean the outer surface of the instrument: 1) Using a lint-free cloth to remove the dust from the outside of the oscilloscope and Tablet1000 Quick guide Copyright © Qingdao Hantek Electronics Co., LTD 4
