Page 5: Safety Instructions
Safety Instructions The instrument is designed according to the requirements of the international electrical safety standard IEC61010-1 for the safety requirements of the electronic testing instruments. The design and manufacture of instruments strictly comply with the requirements of IEC61010-1 CAT.III 1000V over voltage safety standards and pollution level 2. - Page 6 Before using the instrument, please check whether there is any crack or plastic damage in the instrument case. If you do, do not use it again. Before using the instrument, please check whether the probe is cracked or damaged. If so, please replace the same type and the same electrical specifications.
- Page 7 remove the probe on the instrument. Do not use the instrument in the circumstances that the instrument is taken apart or battery cover is opened. It only meets the safety standards when the instrument is used together with the supplied probe. If the probe is damaged and needs to replace, the probe with same model number and same electrical specifications must be used for replacement.
