1.2 Environmental Ratings
The 27MG Ultrasonic Thickness Gage instrument is a rugged and durable instrument
that can be used in harsh environments. The 27MG was designed to meet the
requirement of the IP65 rating (Ingress Protection rating).
Olympus cannot guarantee any level of Ingress Protection rating once the instrument
seals have been manipulated. You must use sound judgment, and take proper
precautions before exposing the instrument to harsh environments.
To maintain the original level of Ingress Protection, you are responsible for the proper
care of all routinely exposed membrane seals. Additionally, you are responsible for
returning the instrument to an authorized Olympus service center on an annual basis
to ensure that the instrument seals are properly maintained.
1.3 Instrument Hardware Components
The 27MG front panel features a display and a keypad. The instrument comes with a
wrist strap. An optional protective rubber boot includes strap rings at the four corners
(see Figure 1-1 on page 17).
