WARRANTY
The manufacturer warrants this product to be free from defects in material and workmanship under normal use
and service for the period of two years from date of purchase, except as hereinafter provided. This warranty
extends only to the original purchaser (a purchase from the manufacturer or a licensed distributor of the
manufacturer is an original purchase). This warranty shall not apply to fuses, batteries, or any product which has
been subject to misuse, neglect, accident, or abnormal conditions of operation.
In the event of failure of a product covered by this warranty, the manufacturer will repair the instrument when it
is returned by the purchaser, freight prepaid, to an authorized Service Facility within the applicable warranty
period, provided manufacturer’s examination discloses to its satisfaction that the product was defective. The
manufacturer may, at its option, replace the product in lieu of repair. With regard to any covered product
returned within the applicable warranty period, repairs or replacement will be made without charge and with
return freight paid by the manufacturer, unless the failure was caused by misuse, neglect, accident, or abnormal
conditions of operation or storage, in which case repairs will be billed at a reasonable cost. In such a case, an
estimate will be submitted before work is started, if requested.
THE FOREGOING WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED,
INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS, OR
ADEQUACY FOR ANY PARTICULAR PURPOSE OR USE. THE MANUFACTURER SHALL NOT BE LIABLE
FOR ANY SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, WHETHER IN CONTRACT, TORT,
OR OTHERWISE.
SOFTWARE WARRANTY

1Safety Instructions
This document contains important information, which should be kept at all times with the instrument during its
operational life. Other users of this instrument should be given these instructions with the instrument. Eventual
updates to this information must be added to the original document. The instrument should only be operated by
trained personnel in accordance with these instructions and local safety regulations.
Acceptable Operation
This instrument is intended only for the measurement of temperature. The instrument is appropriate for
continuous use. The instrument operates reliably in demanding conditions, such as in high environmental
temperatures, as long as the documented technical specifications for all instrument components are adhered to.
Compliance with the operating instructions is necessary to ensure the expected results.
Unacceptable Operation
The instrument should not be used for medical diagnosis.
Replacement Parts and Accessories
Use only original parts and accessories approved by the manufacturer. The use of other products can compromise
the operational safety and functionality of the instrument.

Safety Instructions
12 Rev. G Nov/2015 MI3
The instrument can be equipped with a Class 2 laser. Class 2 lasers shine only within the
visible spectrum at an intensity of 1 mW. Looking directly into the laser beam can
produce a slight, temporary blinding effect, but does not result in physical injury or
damage to the eyes, even when the beam is magnified by optical aids. At any rate, closing
the eye lids is encouraged when eye contact is made with the laser beam. Pay attention to
possible reflections of the laser beam. The laser functions only to locate and mark surface
measurement targets. Do not aim the laser at people or animals.
To prevent possible electrical shock, fire, or personal injury follow these guidelines:
Read all safety Information before you use the product.
Use the product only as specified, or the protection supplied by the product can
be compromised.
Carefully read all instructions.
Do not use and disable the product if it is damaged.
Do not use the product if it operates incorrectly.
Make sure the ground conductor in the mains power cord is connected to a
protective earth ground. Disruption of the protective earth could put voltage on
the chassis that could cause death.
Replace the mains power cord if the insulation is damaged or if the insulation
shows signs of wear.
Use in 110/230 VAC electrical systems can result in electrical hazards and
personal injury, if not properly protected. All instrument parts supplied by
electricity must be covered to prevent physical contact and other hazards at all
times.
The system integrator is responsible for the final safety of the system.

Description
MI3 Rev. G Nov/2015 13
2Description
The MI3 sensor series is the next generation of the well-established “MI class” sensor platform. It will
be capable of covering a broad range of applications. The MI3 sensor series introduces various
network communications, an externally accessible user interface, improved temperature measurement
specifications and capabilities at an economic price.
The MI3 series comes with the following highlights:
Rugged sensing heads survive ambient temperatures to 120°C (248°F) including optimized
performance due to ambient temperature calibration across full ambient temperature range
Special high ambient temperature heads available withstanding up to 180°C (356°F) without
any cooling (LTH models)
Multi head system architecture to allow multiple sensing heads to be multiplexed from a single
communication box
Stand-alone OEM sensing head operation
Intrinsically safe sensing head with Ex Power Supply for installation in hazardous areas (ATEX)
Precision high resolution optics up to 100:1
Up to 10 ms response time
Alarm status indicator
Standard USB 2.0 digital interface
