DF-760E Operator Manual
Manual Version 082416

Your NanoTrace Moisture Analyzer has been designed, manufactured and is
supported under ISO-9001 controls, thus helping to insure the highest possible
standards of quality.
Every analyzer that Servomex manufactures is tested and operated on a
variety of gas concentrations to insure that it functions properly when you
receive it.
The certificate of calibration assures your analyzer has been calibrated on
gases that are traceable to NIST standards. With proper maintenance, your
analyzer should remain calibrated for years.
For a fast and successful startup, please read this manual carefully. There are
important cautions and a number of helpful hints to help you to optimize the
operation of your analyzer.
For more information or if you have questions, please do not hesitate to go to

4. Open the analyzer door, remove any shipping materials and verify that
nothing has come loose during transit.
5. Locate the purifier packed separately and follow the instructions on page
129 for proper installation.
6. The analyzer is set at the factory to operate on 110 VAC or 220 VAC.
Examine the voltage indicator on the rear panel to verify that the voltage is
set as ordered.
7. Save the original container in the event you may need to ship the analyzer
to another location or back to the factory (see Shipping in the Service
section). Note that shipping regulations require that the purifier be
removed from the analyzer and packaged separately as it is considered
hazardous material.

Installation and Maintenance
The NanoTrace Dual Analyzer provides years of accurate and dependable
service if it is set up, operated and maintained properly. It is essential to make
a careful and complete installation as outlined in the Installation and Start Up
section of this manual. It is assumed that NanoTrace Dual Analyzer users are
familiar with the techniques and precautions associated with Ultra-High Purity
(UHP) gas, its plumbing, and devices such as UHP regulators and gas
purifiers, and that the analyzer is used as designed and intended.
Unlike much UHP analytical equipment, NanoTrace Dual Analyzer does not
require constant maintenance. However the maintenance intervals for zero and
span calibrations, as well as addition of Replenishment Solution to the oxygen
sensor and purifier maintenance, must be determined and followed carefully.
Thank You
Thank you for selecting the NanoTrace Dual Analyzer. Servomex designs,
manufactures, exhaustively tests, and supports every analyzer under the
tightest quality controls. You should expect every Servomex analyzer to arrive
in perfect working order and, with good maintenance, provide years of
trouble-free service. Please call your nearest Servomex Business Center if you
need assistance.

ATTENTION : GAZ INERTES, TOXIQUES ET COMBUSTIBLES
The DF-760, DF-750 and DF-745 analyzers have been designed for use with
inert, non-toxic, non-combustible sample gases only, such as nitrogen, helium
or argon. The DF-760, DF-750 or DF-745 may be used with the combustible
gas hydrogen if the analyzer has been factory ordered with the Hydrogen
Service Safety System option. The DF-750 and DF-745 may be used with the
reactive gas pure oxygen. The DF-740 is intended for use with the toxic gas
ammonia. The DF-730 is intended for use with the toxic gas HCl. The DF-
745SG approved gas list is ever expanding, but it includes: N2, O2, H2, He, Ar,
CO2, CO, SF6, Ne, Kr, Xe and N2O. Check your order paperwork to
determine whether your analyzer is intended for use with a toxic or
combustible gas. For toxic and combustible gases, observe the following
special installation and operation precautions:
1) Be sure to know the sample gas composition and the safe handling
requirements for that gas composition.
2) Install a shutoff valve on the sample gas inlet so that gas can be turned
off in an emergency.
3) Check all external plumbing connections for tightness before
pressurizing the sample system.
4) Vent the analyzer outlet into the appropriate facility vent system --
away from personnel (for toxic gases) and away from sources of
ignition (for combustible gases).
5) Turn off the sample gas before disconnecting the analyzer.
6) For many toxic gases a breathing air safety monitor can be purchased
(from a safety products distributor) that will notify the user if an unsafe
amount of the toxic gas is detected.
Servomex cannot be responsible for direct or consequential damages that result
from using the analyzer with these gases.
