WARRANTY

First Year Warranty

The Gentec-EO thermal power and energy detectors carry a one-year warranty (from date of shipment)
against material and /or workmanship defects when used under normal operating conditions. The
warranty does not cover recalibration or damages related to misuse.

Gentec-EO will repair or replace at its option any wattmeter or joulemeter which proves to be defective
during the warranty period, except in the case of product misuse.

Any unauthorized alteration or repair of the product is also not covered by the warranty.
The manufacturer is not liable for consequential damages of any kind.
In the case of a malfunction, contact the local Gentec-EO distributor or nearest Gentec-EO office to

obtain a return authorization number. Return the material to the address below.

Lifetime Warranty

Gentec-EO will warranty any thermal power and energy detector head for its lifetime as long as it has
been returned for recalibration annually from the date of shipment. This warranty includes parts and labor
for all routine repairs including normal wear under normal operating conditions.

Gentec-EO will inspect and repair the detector during the annual recalibration. Exceptions to repair at
other times will be at Gentec-EO’s option.

Not included is the cost of annual recalibration or consequential damages from using the detector.
The only condition is that the detector head must not have been subject to unauthorized service or

damaged by misuse. Misuse would include, but is not limited to; laser exposure outside Gentec-EO’s
published specifications, physical damage due to improper handling, and exposure to hostile
environments. Hostile environments would include, but are not limited to excessive temperature,
vibration, humidity (>80%), or surface contaminants; exposure to flame, solvents or water; and connection
to improper electrical voltage.

2 GENERAL INFORMATION

2.1 INTRODUCTION

The Gentec-EO UM-B Series is a robust line of high performance and high accuracy pyroelectric

wattmeters. Each unit is built for durability, compactness and ease of operation.
The UM-B optical absorber exhibits high damage thresholds and very low reflection.
The UM-B Series benefits from the use of a DB-15 male, “Smart Interface” connector, containing

an EEPROM (Erasable Electrical Programmable Read-Only Memory) programmed with the
calibration sensitivity, the spectral correction factors at different wavelengths and other data
related to the specific UM-B Series wattmeter head. This connector allows the monitor to
automatically adjust its setting to those of the wattmeter being connected.

The DA versions of the UM-B series, to be used with the APM(APM (D) with DB-15 connector)
do not have the “Smart Interface” function. These wattmeters cannot be used with a monitor.
They must be used with an APM, and an oscilloscope or an OEM acquisition system.

Every UM-B Series wattmeter features high intrinsic responsivity and high insensitivity to
electromagnetic interference.

The UM-B Series also offers an exceptionally wide dynamic range and allows power
measurements from UV to the far IR.

UM-B Series wattmeters are designed for user-friendly power measurement of CW lasers using a
monitor.

UM-B Series wattmeters require no external power source1. They can also be used with a 1 M
input impedance oscilloscope1 (or fast chart recorder). The calibrated V/W sensitivity is

documented in the calibration certificate of each unit. The spectral correction of this sensitivity is
also documented in the “Personal wavelength correction” certificate.

Each probe also includes a standard optical stand and post.

An APM is required.

2.2 UM-B SERIES “SMART INTERFACE” CONNECTOR 2

The DB-15 male “Smart Interface” connector contains an EEPROM (Erasable Electrical Programmable
Read-Only Memory) programmed with the calibration sensitivity and other data related to the specific UM-

B wattmeter in use. Faster set-ups are obtained because the monitor automatically adjusts to the
characteristics of the wattmeter, when the “Smart Interface” is connected to the monitor.

The DB-15 “Smart Interface” connector pin-out is (see Fig. 1-1):
