Cleaning
To clean the instrument, wipe it gently with a soft cloth moistened with
water or mild detergent. Never use solvents such as benzene, alcohol,
acetone, ether, ketones, thinners or gasoline, as they can deform and
discolor the case.
Storage
• Storage temperature and humidity should be kept between -10 and 50°C (14 to
122°F), at less than 80% RH.
• Do not store or use the instrument where it could be exposed to direct sunlight,
high temperature or humidity, or condensation. Under such conditions, the
instrument may be damaged and insulation may deteriorate so that it no longer
meets specifications.
• When storing the instrument for a long time (1 year or more), the specifications
are no longer guaranteed. Therefore, before use, have the instrument recali-
brated.
