WARNINGS
To avoid personal injury, follow these guidelines.
•
Before initial use, or after transport, or after storage in humid or semi-hu-
mid environments, or anytime the instrument has not been energized for
more than 10 days, the instrument needs to be energized for a “dry-out”
period of 2 hours before it can be assumed to meet all of the safety re-
quirements of the IEC 1010-1. If the product is wet or has been in a wet
environment, take necessary measures to remove moisture prior to apply-
ing power such as storage in a low humidity temperature chamber operat-
ing at 50 degree centigrade for 4 hours or more.
•
Use only a grounded AC mains supply of the appropriate voltage to
power the instrument. The dry-well requires a maximum of 1 amp, 50/60
Hz, 115/230 VAC (±10%).
•
DO NOT
connect this unit to a non-grounded, non-polarized outlet.
•
DO
use a ground fault interrupt device.
•
HIGH VOLTAGE
