IMP57 2. GENERAL DESCRIPTION Dear Customer, we thank you for your patronage. The instrument you have just purchased will grant you accurate and reliable measurements provided that it is used according to the present manual’s instructions. The instrument was designed to grant the user the utmost safety conditions thanks to a new concept assuring double insulation and overvoltage category III 240V (to Earth).
You are recommended, however, to carry our a rapid check to detect any possible damage which might have been caused during transport. Should this be the case, immediately contact HT Italia. Check also that the packaging contains all the parts listed under paragraph 9.3. In case of discrepancies contact the dealer.
Check the nominal voltage range (220 415V) and the frequency range (47.5 52.5Hz). Also check anomalous situation in paragraph 6.1.5, 6.2.5, 6.3.5, 6.4.5 and 6.5.5. 4.2.
