SAFETY INFORMATION
Do not use a Gentec-EO device if the monitor or the detector looks damaged or if you suspect that the device
is not operating properly.
Appropriate installation must be done for water-cooled and fan-cooled detectors. Refer to the specific
instructions for more information. Wait a few minutes before handling the detectors after they are powered
up. The surfaces of the detectors get very hot, and there is a risk of injury if they have not cooled.
Note: This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy. If not installed and
used in accordance with the instructions, it may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, try to
correct the interference by taking one or more of the following steps:
Reorient or relocate the receiving antenna.
Increase the distance between the equipment and receiver.
Connect the equipment to an outlet that is on a different circuit than the receiver.
Consult the dealer or an experienced radio/TV technician for help.
Caution: Changes or modifications not expressly approved in writing by Gentec-EO Inc. may void
the user’s authority to operate this equipment.

1.2. INTRODUCTION
To obtain the full performance from the MAESTRO, we recommend that you read this manual carefully.
The MAESTRO is a microprocessor-based power and energy meter that uses the latest technology to provide
a multitude of options in a user-friendly environment. It is intuitively accessible using a touchscreen. It is a
complete power and energy meter. The MAESTRO provides a statistical analysis of your measurements. It
allows you to store data on an external USB key. Moreover, the MAESTRO can be updated by connecting a
USB key with the new file available on our website in the download section.
The MAESTRO has enhanced network capabilities that take further advantage of the USB port for data
acquisition and remote control. In addition to the external USB key, it can also transfer data files to a PC for
more sophisticated data analysis. Furthermore, the MAESTRO responds to commands through the PC
interface using the USB port. To transform your PC screen into a virtual MAESTRO, look for the easy-to-use
communications software on our website.
There is no need to enter the head specifications when connecting the new Gentec-EO power or energy
detector heads, for heads version 5 and above. The MAESTRO is already internally set to accept the latest
Gentec-EO wattmeter and joulemeter heads with a DB-15 connector. The MAESTRO supports both fast and
slow heads with a rise time from 5 s to 10 s.
The MAESTRO can reread heads in hot plug situation. Before inserting a new head, wait for the MAESTRO to
stop displaying numbers. Once the head has been detected, the monitor will wait 2 seconds to ensure that
the head is properly inserted. If you do not respect these conditions and the head is not read correctly, reboot
the MAESTRO.
1.3. EASY SOFTWARE UPGRADE
Keep in touch with the latest improvements to our user-friendly software by going to our website at
www.gentec-eo.com. Download the latest software version anytime and install it on the MAESTRO with the
USB key. You will find all the necessary information on downloading and upgrading in section 4.2.

The 5µV offset can introduce an error into low power measurements with low sensitivity detectors. It is essential to use
the zero offset to re-zero the MAESTRO before making a measurement in these conditions. It is always good practice to
use the zero offset. See section 2.2.
