Addendum to M100E Manual - P/N 04515PREFACE
1. PREFACE
NOTE
The information contained in this addendum is pertinent to M100EU analyzers running software revision
F.0. Some or all of the information may not be applicable to later revisions of software.
The software revision your analyzer is running is displayed in the upper left-hand corner of the display
any time the instrument is in SETUP mode.
This addendum is based on the Model 100E Operators Manual (P/N 04145). In most ways the M100EU is
identical to the M100E in design and operation, therefore most of the basic set up information, operating
instructions as well as calibration, maintenance, troubleshooting and repair methods are found in that manual.
This addendum documents only those areas where the M100EU is different in design or operating method from
the M100E.
Therefore this addendum includes instructions and information regarding:
Additional Test Functions
Adjusting the PMT HV for “Factory Calibrations”

however it is anticipated that the M100EU will qualify as Reference Method Number EQSA-0495-100 per 40
CFR Part 53 in the near future. Please see section 2.2 of the M100E manual, P/N 04515 for details.

3.1 UNPACKING THE M100EU
Unpack the M100EU as per the directions in Section 3.1 of the M100E Manual - P/N 04515, with the following
change. There are two redheaded shipping screws that hold down the PMT/Sensor assembly and must be
removed prior to operation. They are located along the base of the PMT housing adjacent to the chassis.
3.2 INTERNAL LAYOUTS
Figures 3-1 replaces Figure 3-9 in the M100E manual. The primary difference between the M100EU and M100E
layouts is the differences in the PMT Housing, the location of the PMT preamp PCA and the addition of a Sync
Demodulator PCA.

NOTE
For the most part the operation instruction for the M100EU are the same as those described in Chapter 6
of the M100E Manual - P/N 04515 with the exception that there are additional test parameters and setup
procedures.
6.1 ADDITIONAL TEST PARAMETERS
Please see Section 3.3 above for details on the additional test parameters.
6.2 STBL MENU: SETUP FOR THE THREE STABILITY
FUNCTIONS
There is an additional submenu on the Secondary Setup Menu in the M100EU’s software. The STBL menu, see
Figure 6-1 allows the user to modify the settings for the three stabili
Functions on the front panel and are available via the serial data port and that can be logged with the iDAS.
Test Function STABIL, CONC1 in the menus below, is equivalent to the standard M100E STABIL function and is
useful when conducting calibrations and other operations in which the operator has limited time to view the
display. CONC2, which is the same as the STABIL2 test function has been configured so that it calculates
stability in the same way as required by the EPA. STABIL2 is useful when comparing instruments against the
EPA standard but is very slow and difficult to use for calibration or other activities where the operator must wait
for analyzer to settle to the desired value. UVLAMP is the same as UV STAB on the front panel is a diagnostic
that can be used to understand the stability of the UV lamp.

Addendum to M100E Manual - P/N 04145 CALIBRATION PROCEDURES
7. CALIBRATION PROCEDURES
Calibration of the M100EU should be performed according to the procedures described in Chapters 7 & 8 of the
M100E Manual - P/N 04145. However, delivering span and zero gases for the lower ranges that the M100EU is
designed for can be difficult. For best results when calibrating the M100EU, wait one hour for the instrument to
stabilize when delivering zero and span gases before pressing the zero and span buttons. Attention must be
paid to the quality of the gasses, the level of contaminants in the gases as well as the history and conditioning of
the gas delivery components. Only Teflon or glass should be used for any “wetted” surfaces that the calibration
gasses contact. All delivery system components should be conditioned by running span gas for a minimum of
four hours before conducting actual span calibrations.

Addendum to M100E Manual - P/N 04145 THEORY OF OPERATION
10. THEORY OF OPERATION
The M100EU is a modified M100E. The primary differences are the way in which the PMT and UV reference
signals are acquired and processed. The M100EU has no shutter but rather employs synchronous
demodulation to capture the dark and light PMT and UV reference signals several times per second. A printed
circuit board, the Sync Demodulator, attached to the end of the PMT housing, on the sensor assembly, includes
circuitry that digitizes the PMT and UV reference signals and synchronizes the operation of the UV source with
these measurements. This method of signal processing minimizes the error that changing offsets could make in
an instrument that is designed to operate near its detection limit.
10.1 ELECTRONIC OPERATION
The following information is in addition to that contained in Section 10.2 of the M100E Manual - P/N 04145.
10.1.1 SENSOR MODULE
At the heart of the M100EU’s signal processing, illustrated in Figure 10-1 below, is the Synchronous
Demodulator PCA. The PCA is attached to the end of the PMT housing and serves to seal the end of the PMT
housing. The sync demodulator controls the operation of the UV Lamp driver, digitizes the analog output
signals from the PMT UV reference detector and PMT temperature sensor, controls the PMT cooler (TEC),
controls the PMT HV via a local I2C bus, and communicates with the analyzer’s CPU over the master I2C bus.
Digitized and processed data from the UV reference and PMT are passed to the analyzer’s CPU over the master
I2C bus and data for control of the PMT HV control DAC is passed from the CPU to the DAC on the PMT
preamp via the microcontroller on the Sync Demod board.
