Introduction The GE Sensing Moisture Monitor MMS-3 is a one- or two-channel
analyzer designed to measure dissolved moisture concentration in
gases and non-aqueous liquids, and dissolved oxygen concentration
in gases.
A microprocessor-based instrument, the MMS-3 combines hardware
and software to make various measurements. The user connects the
needed inputs (moisture probes, pressure transmitters, oxygen cells,
etc.) to the back panel of the electronics unit using the appropriate
cables. Typically, the user installs moisture probes and oxygen cells
into the process using a sample system that is specifically designed
for the application. The sample system delivers a sample of the
process gas or liquid to the probes. The probes then send signals to
the MMS-3 electronics unit, which interprets the signals and converts
them into measurements.
The complete analyzer, including electronics, cables and
measurement probes, forms a “system” that is designed to monitor the
process accurately and reliably. The following sections discuss each
part of this “system.”
Electronics Unit The center of the “system” is the electronics unit. The electronics unit
has many components, including the terminal blocks for all
connections, an RS232 port, a Liquid Crystal Display (LCD), a
keypad, and menu keys (see Figure 1-1 on page 1-2). The MMS-3 is
also available with an optional battery pack.
The back panel of the electronics unit consists of the terminal blocks
for connecting moisture probes, oxygen cells, recorders and optional
alarms (standard or hermetically sealed). The MMS-3 also provides
connections for two isolated outputs per channel. Input connections
for the M and TF Series moisture probes, as well as the Delta F
oxygen sensors, are intrinsically safe.
As an optional feature, the MMS-3 provides connections for two
auxiliary inputs (not intrinsically safe) for each channel. The auxiliary
inputs can accept signals from any 0/4 to 20-mA or 0 to 2-VDC
device, including other GE Sensing analyzers.
The RS232 port enables the user to connect a remote terminal, printer,
or computer to the MMS-3. Using an optional PanaView™ software
package, the user can also set up and operate one or more analyzers
from a remote location, program user functions, transfer data, and
create data logs.

1-2 Features and Capabilities
Electronics Unit (cont.) The front panel of the electronics unit contains a 2-line x 20 character
Liquid Crystal Display (LCD) to show measurements, a 4 x 4 matrix
keypad for entering data and operating the MMS-3, and four function
keys.
The MMS-3 is also available with an optional rechargeable battery
pack that makes it ideal for survey applications. The user can move
the MMS-3 from location to location to take spot samples and store
measurements. When fully charged, the battery pack provides eight
hours of continuous operation.
The BASEEFA-approved electronics unit is available in rack mount,
portable bench mount, and panel mount versions. The electronics unit
is also available in NEMA-4X weatherproof and NEMA-7 explosion-
proof housings, but these packages are not BASEEFA approved.
IMPORTANT: Only the MMS-3’s that have serial numbers 2001 and
above are intrinsically safe.

Probes Probes are the part of the system that come into contact with the
process flow. The MMS-3 uses various types of probes to fit the needs
of different applications.
The term “probe” includes devices such as moisture sensors, pressure
transducers, and oxygen cells. Although users can supply their own
probes for certain measurements, GE Sensing provides the following
standard probes to make moisture, temperature, pressure, and oxygen
measurements:
•Moisture (M) Series - moisture and temperature (in gases and
liquids)
•Three Function (TF) Series - moisture, temperature, and pressure
(in gases and liquids)
•Delta-F Cells - oxygen measurement (in gases).
The most commonly used probes are discussed in more detail below.
M Series and TF Moisture
Probes The M Series and TF Series probes are very similar. Both probes use
GE aluminum oxide sensors to measure moisture, and thermistors to
measure temperature (the thermistor is optional). The TF Series,
however, has an optional built-in strain-gage-type pressure
transducer. The sensor assemblies are secured to a probe mount and
are usually protected with a sintered stainless-steel shield (TF-9
probes typically do not have a shield). Other types of shields are
available. See Figure 1-2 below and Figure 1-3 on page 1-4.
When using an M Series probe, a separate pressure transmitter is
required if in-line pressure measurement is needed. The MMS-3 can
use any pressure transmitter with a 0/4 to 20-mA and/or a 0 to 2-V
output. Alternatively, the user can enter fixed values for temperature
and pressure into the MMS-3 memory if the process conditions are
constant.

1-4 Features and Capabilities
M Series and TF Moisture
Probes (cont.)
Figure 1-3: TF Series Probe
Although the M and TF Series probes may be installed directly into
the process line, they are usually inserted into a sample system. The
sample system protects the probes and enables the user to easily
remove the probes for calibrating, servicing, and cleaning. Sample
systems also control the flow of the process stream so that it is within
the specifications of the measurement probe or cell.
The M and TF Series probes, when operated with a BASEEFA-
approved MMS-3, are intrinsically safe (see Chapter 3, Specifications,
in the Startup Guide, for BASEEFA certification numbers) and are
designed to meet requirements of IEC/CENELEC zone 0 areas.
The M and TF Series probes measure moisture content in a standard
range from -110°C to 20°C (-166°F to 68°F) dew/frost point
temperature, and optionally from -110°C to 60°C (-166°F to 140° F).
Both probes optionally measure temperature in a range of -30°C to
70°C (-22°F to 158°F).The TF probe optionally measures pressure
from 30 to 300, 50 to 500, 100 to 1000, 300 to 3000, and 500 to 5000
psig.
Pressure Transmitter In addition to the M Series probe, a separate pressure transmitter may
be needed for on-line pressure measurement. Pressure measurement
is a necessary input for conversion to certain moisture parameters,
such as parts per million by volume water vapor in a gas. The
MMS-3 can use any pressure transmitter with a 0/4 to 20 mA or 0 to 2
V output. Additionally, constant temperature and pressure can be
programmed into the MMS-3 if these process conditions are constant.
Temperature measurement is a necessary input for conversion to
certain moisture parameters, such as parts per million by weight water
vapor dissolved in a liquid. It is also necessary so maximum
temperature/pressure conditions are not exceeded.

Delta F Oxygen Cell The MMS-3 standard oxygen measurement probe is the Delta-F Cell.
Overall oxygen content range measured using this cell is from 0 to
25%. You may choose from seven standard oxygen ranges. The
lowest standard range is 0 to 1/10/100 ppm; the highest standard
range is 0 to 25% oxygen. An ultra-low-range sensor that covers
0-500 ppbv and is sensitive to less than 5 ppb is also available. The
MMS-3 can also accept oxygen inputs from other GE Sensing oxygen
sensors using the auxiliary inputs.
If your application has a high concentration of acid-forming
components, GE Sensing supplies a STAB-EL option for the Delta F
Cell. The STAB-EL option is specially designed to effectively
neutralize these components from the sample gas stream.
The Delta F Cell is available in a general purpose model with both a
top and bottom drain, or only a top drain as shown in Figure 1-4
below. The Delta F Cell is usually installed in its own sample system.
The Delta F Cell is optionally available with VCR®fittings, mounted
in a NEMA-4X enclosure for weatherproof corrosion resistant
applications, or mounted in a NEMA-7 enclosure for hazardous areas.
The Delta F Cell is BASEEFA-approved, and when connected to a
BASEEFA-approved MMS-3, provides certified intrinsic safety. See
Chapter 3 of the Startup Guide, Specifications, for certification
numbers.

1-6 Features and Capabilities
Cabling Each probe requires an interconnecting cable. Cables differ
depending on the probe. The various cables are discussed below
under the appropriate probe type. All of the cable assemblies can be
ordered from GE Sensing.
IMPORTANT: See the Calibration Data Sheets, shipped with the
probes, to connect the probes to their corresponding
channels. If a probe is connected to the wrong
channel, the meter will display incorrect data.
IMPORTANT: To maintain good contact at each terminal block and
to avoid damaging the pins on the connector, pull the
connector straight off (not at an angle), make cable
connections while the connector is away from the
unit, and push the connector straight on (not at an
angle) when the wiring is complete.
M Series and TF Series
Probes The M and TF Series Probes are connected to the analyzer with a
special GE Sensing shielded cable. Probes can be located up to 600 m
(2000 ft) from the MMS-3 (consult GE Sensing for distances up to
1,200 m). To measure pressure with a TF Probe, the maximum cable
length is approximately 152 m (500 ft). Small electrical offsets,
especially with longer cables, are possible and should be corrected as
described in Performing an MH Calibration Test/Adjustment, in
Chapter 1 of the Service Manual.
Delta F Oxygen Cell The standard Delta F Oxygen Cells are connected to the analyzer with
a four-wire shielded cable (22 AWG). Oxygen cells with a range from
0 to 1/10/100 ppmvor 0 to 0.5/5/50 ppmvcan be located up to 15 m
(50 ft) away from the analyzer. All other oxygen cells can be located
up to 91 m (300 ft) away. Consult GE Sensing for longer cable
lengths.
Pressure Sensors The MMS-3 accepts either pressure transducers or pressure
transmitters. Most pressure transducers can be connected with a
standard four-wire shielded cable. Most pressure transmitters are
connected using either a two or four-wire non-shielded cable and can
be either loop- or self-powered.
RS232 Communications
Port A personal computer or serial printer can be connected to the MMS-3
RS232 communications port using a standard serial cable. The
MMS-3 has a special switch that enables you to configure the unit as a
Data Terminal Equipment (DTE) or a Data Communications
Equipment (DCE) device. (See Chapter 1 in the Service Manual for
details on DTE/DCE configuration.)

Features and Capabilities 1-7
March 2008
User Program The MMS-3 has a user program that is accessed and controlled by its
keypad and the four function keys. The user program enables the user
to enter the necessary probe data, set up the LCD screen, and control
the operational features of the MMS-3. The MMS-3 stores this in
battery-backed RAM for up to five years, even when power is off.
The MMS-3 user program consists of the following 12 main menus:
•SYSTEM - This menu enables the user to enter calibration and
configurations data.
•AUTOCAL - To compensate for any drift in the electronics, the user
can program the MMS-3 to calibrate itself automatically at pre-
selected intervals.
•USER - This menu is used to enter a saturation constant which the

Startup Procedure Sensor configuration and system calibration data for your MMS-3 are
entered at the factory. After you unpack the unit, use the sections that
follow to verify that your system is working properly and set up the
screen to display the desired measurements.
Powering Up The MMS-3 has a universal power supply that automatically adjusts
to line voltages from 95 to 260 VAC, and a portable battery pack
(optional). After making electrical connections as described in
Chapter 1 of the Startup Guide, press the [ON] switch to power up the
MMS-3.
IMPORTANT: For compliance with the EU’s Low Voltage Directive
(IEC 1010), this unit requires an external power
disconnect device such as a switch or circuit breaker.
The disconnect device must be marked as such,
clearly visible, directly accessible, and located
within 1.8 m (6 ft) of the MMS-3. The power line is
the main disconnect device.
Caution!
Do not operate the Delta F Oxygen Cell for extended
periods of time at oxygen concentrations that are over
range. Trace and low percent range sensors may be
damaged if exposed to high levels of oxygen, such as air,
for long periods (>1 hour) while the MMS-3 is on.
If exposure is unavoidable, either disconnect the oxygen
cell from the MMS-3 or equip the sample system with a
valve that allows the cell to be switched to purge gas.
The MMS-3 normally shows a series of messages that indicate it is
functioning normally, and then begins displaying data.

2-2 Basic Programming
Using the Keypad and
Passcode Use the following sections to become familiar with the key functions
and discover the passcode number you will need to access the user
program.
Key Functions The function keys to the right of the keypad are used in the following
manner:
•[MODE] - modifies or selects the measurement mode to display.
•[CHAN] - toggles between channels (only works with units that have
two channels installed).
•[PROG] - accesses the user program.
•[RUN] - exits the Modify Display Mode or the user program (except
during numeric entry) and returns to displaying measurements.
The keypad below the MMS-3 screen consists of 16 keys (including
the [.] and [–] symbols), two arrow keys, and two response keys,
([YES] and [NO]). The numeric keys are for numeric entry only;
however, the arrow and response keys have more than one function.
The arrow keys perform three functions:
•arrow keys - scroll through the screen selections by moving the
brackets forward or backward to the desired location.
•left arrow key - moves backward and erases during numeric entry.
•right arrow key - moves the cursor to the desired location during
numeric entry and accepts a change at the present location.
The response keys perform three functions:
•[YES] or [NO] - respond to questions and/or exit a screen.
•[YES] - confirms an entry or retrieves a previous number after you
erase it.
•[NO] - moves backward through the menu.
IMPORTANT: After pressing a key, wait for the unit to perform the
desired function before executing another key
function.
Passcode To enter the user program you must enter a passcode. The passcode
prevents unauthorized users from changing data. When entering the
user program, the MMS-3 prompts for the passcode. Refer to the end
of this chapter for your default passcode.

Displaying
Measurements The MMS-3 begins displaying measurements immediately after
power-up. It provides two lines in order to display measurements.
You may select the measurement mode for each line as described in
the procedure below.
Since the display has a limited amount of space, the MMS-3 uses
abbreviations to represent the displayed measurement mode and units
as shown in Table 2-3 on page 2-5.
Press the [MODE] key to enter the Modify DSP Mode.
Display Page: 1 The MMS-3 can display six
pages of measurements, each
showing two different
parameters. Use the numeric
keys to enter the desired page
and press [YES].
Press YES to Edit
Modify DSP Mode P1 Use the arrow keys to move the
brackets to the desired line you
want to edit and press [YES].
LINE1 [LINE2]
Line 2 DSP Mode P1 Use the arrow keys to move the
brackets to the desired channel
you want to display and press
[YES].
[CH 1] CH 2
Select DSP Mode P1 Use the arrow key to move the
brackets to the measurement
mode and press [YES]. See

Measurements (cont.)
When selecting a measurement mode, please remember that some
measurement modes require multiple inputs. For example, to display
ppmv, you need a moisture and pressure input. Table 2-2 below shows
a list of measurement modes that require multiple inputs and what
you need to display them. If the MMS-3 displays “No Data,” you may
have to reconfigure the channel. Refer to Reconfiguring a Channel
for a New Sensor on page 3-35.
