Specified accuracy is valid if 3-wire test lead is used while it is valid up to 100 M: if tip commander is used. Specified accuracy is valid up to 100 M: if relative humidity > 85 %. In case the instrument gets moistened, the results could be impaired. In such case, it is recommended to dry the instrument and accessories for at least 24 hours. The error in operating conditions could be at most the error for reference conditions (specified in the manual for each function) r5 % of measured value. The insulation resistance results in Autotest may slightly differ in comparison to results in Single test mode because of the three wire connection and the internal resistance of the measuring instrument.

Advances in the topical treatment of acne and rosacea From: Journal of Drugs in Dermatology | Date: 9/1/2004 | Author: Ceilley, Roger I. Acne and rosacea are common skin diseases which may present similarly and both involve inflammation. Both can result in significant cosmetic impairment and lead to quality of life decrements if not optimally treated. The conventional approach for both d
Skin Care Good skin care is vital for the prevention and management of occupational contact dermatitis and eczema. Undamaged skin provides an excellent natural barrier to skin irritation and the development of allergy. Understanding what substances or conditions aggravate the skin and avoiding them is also very important. Skin care involves several different components, and it is like a pa
