Safety requirements EN When operating: below 3,000 meters. When not operating: below 15,000 meters. Installation (over voltage) Class This product is powered by a main power source that complies with Installation (over voltage) Class II. Warning: Make sure that no overvoltage (such as that caused by lightning) reaches the product. Otherwise the operator may be in danger of receiving an electric shock. 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. Degree of pollution Class 2 Pollution level definition ⚫ Level 1: No pollution, or only dry non-conductive pollution. This pollution level has no impact. For example: clean room or air-conditioned office environment. ⚫ Level 2: Generally, only dry non-conductive pollution. Temporary conduction due to 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 HDG3000B User manual Copyright © Qingdao Hantek Electronics Co., LTD 4
