Safety Precautions

The RD-MV200 conforms to IEC safety class I (AC power supply models are provided
with terminal for protective grounding), Installation Category II, and EN61326-1 (EMC
standard), class A (use in a commercial, industrial, or business environment).
The following general safety precautions must be observed during all phases of
operation. If the RD-MV200 is used in a manner not specified in this manual, the
protection provided by the RD-MV200 may be impaired. Omega assumes no liability for
the customer’s failure to comply with these requirements.

The following symbols are used on the RD-MV200.

“Handle with care.” To avoid injury, death of personnel or damage to
the instrument, the operator must refer to the explanation in the User’s
Manual or Service Manual.

ii

Safety Precautions

Make sure to comply with the following safety precautions. Failure to comply may
result in injury or death (electric shock hazard).

WARNING

Power Supply

Ensure that the source voltage matches the voltage of the power supply before
turning ON the power.

Connecting to the power supply

To prevent the possibility of electric shock or fire, use parts provided by Omega
in connecting to the power supply. For AC power supply models, the power
plug must be plugged into an outlet with a protective earth terminal. Do not
invalidate this protection by using an extension cord without protective earth
grounding.

Protective Grounding (AC power supply models)

Make sure to connect the protective grounding to prevent electric shock before
turning ON the power.

Necessity of Protective Grounding (AC power supply models)

Never cut off the internal or external protective grounding wire or disconnect the
wiring of the protective grounding terminal. Doing so poses a potential shock
hazard.

Defect of Protective Grounding

Do not operate the instrument when the protective grounding or the fuse might
be defective. Also, make sure to check them before operation.

Fuse

To prevent fire, only use a fuse that has a rating (voltage, current, and type) that
is specified by the instrument. When replacing a fuse, turn OFF the power
switch and unplug the power cord. Never short the fuse holder.

Do Not Operate in Explosive Atmosphere

Do not operate the instrument in the presence of flammable liquids or vapors.
Operation of any electrical instrument in such an environment constitutes a
safety hazard.

Do Not Remove Covers

Some areas inside the instrument have high voltages. Do not remove the cover
if the power supply is connected. The cover should be removed by Omega’s
qualified personnel only.

External Connection

Connect the protective grounding before connecting to the item under
measurement or control unit.

Damage to the protective housing

Using the instrument in a manner not specified in this manual can damage the
instrument’s protective housing.

1.1 Overview of the RD-MV200

Unlike conventional recorders that record data on charts, the RD-MV200 displays the
measured data acquired in the internal memory to a LCD in the form of waveforms,
numerical values, and bar graphs. The measured data can also be saved to external
storage media such as floppy disks, Zip disks, and ATA flash memory cards.

The data that have been saved to an external storage medium can be displayed on a PC
using the standard software that comes with the package. The data can also be loaded
into the RD-MV200 to be displayed.
By using the Ethernet interface that comes standard with the RD-MV200, the data can be
transferred to a server on a network (client function). The data stored on the RD-MV200’s
external storage medium can also be read from a PC on the network (server function).

1.2 Functions of the Input Section

Number of Measurement Channels/Scan Interval

The number of measurement channels and scan intervals for different models are listed
in the table below. For the procedure related to setting the scan interval, see section 5.9.

Model Number of Measurement Channels Scan interval

RD-MV204 4 channels 125 ms or 250 ms
RD-MV208 8 channels 125 ms or 250 ms
RD-MV210 10 channels 1 s or 2 s
RD-MV220 20 channels 1 s or 2 s
RD-MV230 30 channels 1 s or 2 s

Input Type and Computation

You can select the input type of a measurement channel from DC voltage, thermocouple,
resistance temperature detector (RTD), and digital input (contact signal or voltage
signal). You can also perform computation on the measured data such as the
“difference,” “square root,” and “scaling.”
The input type and computation are configured as an “input mode” on the RD-MV200.
For the procedure related to setting the different modes, see sections 5.1 to 5.7.

Input Mode Notation*1Description

DC voltage Volt Measures a DC voltage in the range ±20 mV to ±20 V.

root is displayed as the measured value of that channel.
The computed result can be scaled to a value in the
appropriate unit and displayed.

“thermocouple,” “RTD,” or “digital input,” the input signal
can be converted to a value in the appropriate unit desired
and displayed.

measurement channels.
*2 This is optional.
*3 This item defines the type of signals that can be connected to the input terminal when the

input mode is set to “Difference,” “Square root,” or “Scaling.” The description of the input

types, “DC voltage,” “Thermocouple,” “Resistive temperature detector,” and “Digital input,” are

the same as the descriptions given for the input modes, “DC voltage,” “Thermocouple,”

“Resistive temperature detector,” and “Digital input,” respectively.

1.2 Functions of the Input Section

If the signal to be measured is a DC current, a shunt resistance is attached to the input
terminal to convert the current signal to a voltage signal. The input mode is set to “DC
voltage” in this case. For the various types of shunt resistors and the procedure related
to setting the current input, see section 5.1.

Input Range and Measurable Range

You can select the “Input range” that is appropriate for the input signal for “DC voltage,”
“Thermocouple,” “RTD,” and “digital input.” (For example, R, S, B, K, E, J, T, N, W, L,
and U are available input ranges for “Thermocouple.”) For each “Input range,” a
measurable range is defined (for example, the measurable range for R of
“Thermocouple” is “0.0°C to 1760°C”). For details, see section 14.1.

Burnout

When measuring temperature using a thermocouple and the thermocouple burns out,
you can specify the measurement result to be set to positive over range*

over range.*

Burnout can be set on each measurement channel. The initial setting is

set so that burnout is not indicated. For the setting procedure, see section 5.9.

*1 Positive over range is a condition in which the input signal is over the upper limit of the

measurable range. The measured value is indicated as “+

*2 Negative over range is a condition in which the input signal is below the lower limit of the

measurable range. The measured value is indicated as “-

Reference junction compensation (RJC)

When measuring the temperature using a thermocouple, the reference junction
compensation can be used. You can select whether to use the reference junction
compensation provided by the RD-MV200 or external reference junction compensation.
If you are using external reference junction compensation, you will also set the
reference voltage. The initial setting is set so that the reference junction compensation
provided by the RD-MV200 is used. For the setting procedure, see section 5.9.

Filter and Moving Average

The filter and moving average are used to suppress the effects of noise that is riding on
the signal. Filtering is provided on the RD-MV204 and RD-MV208. Moving average is
provided on the RD-MV210, RD-MV220, and RD-MV230. The filter or moving average
can be set on each channel. For the setting procedure, see section 5.8.

Filter function (RD-MV204 and RD-MV208)

Suppresses the effects of noise above the frequency determined by the specified time
constant. The time constant can be set to 2 s, 5 s, or 10 s. The filter is initially turned
OFF.

Moving Average (RD-MV210, RD-MV220, and RD-MV230)

The input signal of the measurement channel is set to the averaged value of the m most
current data points (the number of moving-averaged data points) acquired at the scan
interval. The number of moving-averaged data points can be set in the range 2 to 16.
The moving average is initially turned OFF.

Integration Time of the A/D Converter

The RD-MV200 uses an A/D converter to convert the sampled analog signal to a digital
signal. By setting the integration time to match the time period corresponding to one
cycle of the power supply or an integer multiple of one cycle, the power supply frequency
noise can be effectively eliminated. The integration time of the A/D converter is selected
according to the model from the table below. If “Auto” is selected, the RD-MV200 will
automatically detect the power supply frequency and select 16.7 ms or 20 ms. Because
100 ms is an integer multiple of 16.7 ms and 20 ms, this setting can be used to eliminate
the power frequency noise for either frequency, 50 Hz or 60 Hz. 100 ms is available on
the RD-MV210, RD-MV220, and RD-MV230. For the setting procedure, see section 5.9.

Updating the Waveform and Updating the Numerical Display

One division on the RD-MV200 consists of 30 dots on the LCD. The displayed
waveform is updated at an interval corresponding to one dot. This interval is
determined by the time period corresponding to one division (referred to as the display
update rate). The relationship between the display update rate and the speed of
movement of waveforms is as follows:

Display Update 15 s* 30 s* 1 min 2 min 5 min 10 min 20 min 30 min 1 h 2 h 4 h
Rate (/div)

of waveforms
(approximate value, mm/h)

* for RD-MV204 and RD-MV208 only

Note

The speed of movement of the trend display along the time axis is derived from the following

equation given the dot pitch of the LCD (0.33 mm):

The speed of movement of the trend display along the time axis = 30 (dots) x 0.33 (mm) x 60

(min)/display update rate (min)

1-6

Measured/computed values are updated every second. However, when the scan
interval on the RD-MV210/RD-MV220/RD-MV230 is 2 s, the display update rate is also
2 s.

1.3 Display Function

Displayed Data

The data displayed on the screen are a maximum and minimum values of the data that
are sampled at the scan interval, within the time period corresponding to one dot.

When the display update rate is set to one
minute, the time period corresponding to
one dot (the sampling interval of displayed
data) is 2 s.

The time period corresponding to one dot is called “the sampling interval of displayed
data.” The sampling interval of displayed data is determined by the display update rate.
The relationship between the display update rate and the sampling interval of displayed
data is as follows:

Acquiring Data to the Internal Memory

Display data and event data

The measured/computed data are first acquired to the RD-MV200’s internal memory as
two types of data, display data and event data. Then, the data are saved to the external
storage medium automatically or when the external storage medium is inserted into the
drive. You can select whether to save the measured/computed data as display data,
event data, or as both.
The capacity of the internal memory for acquiring display data and event data is 1.2 MB.
When the measured/computed data are saved as both display data and event data, 0.9
MB is used to save display data and 0.3 MB is used to save event data.

Display data are used to display waveforms on the RD-MV200’s screen. Display data
consists of maximum and minimum values of the measured or computed data sampled
at the scan interval within the time period corresponding to one dot on the time axis on
the screen. Display data can be likened to the conventional recording on the chart sheet
and are useful for long-term observations.
Event data are instantaneous values of the measured/computed data at specified
sampling intervals of the event data. By setting the sampling interval equal to the scan
interval, all measured or computed data sampled at the scan interval can be saved. In
addition, the event data generated when an event occurs (an alarm, for example) can
also be saved. This is useful when you wish to observe the measured/computed data in
detail.
For detail, see sections 8.1 and 8.2.

1.4 Storage Function

Manual sampled data

Every time a given key operation is carried out, all measured/computed data
(instantaneous values) at that point are acquired to the internal memory. However, this
excludes measurement channels that are skipped and computation channels that are
turned OFF. For the action of acquiring data and the operating procedure, see sections

8.1, 8.3, and 8.12.

TLOG data (only on models with the optional computation function (/M1)

The average, maximum, minimum, sum, or maximum - minimum can be computed for
the specified channels at predetermined intervals and the result can be acquired to the
internal memory. You can specify the interval. For the action of acquiring data, see
sections 8.1 and 8.3.

Report data (only on models with the optional computation function (/M1)

The average, maximum, minimum, and sum can be computed for the specified channels
at predetermined intervals and the result can be acquired to the internal memory. You
can select one hour (hourly report), one day (daily report), one day/one week (daily and
weekly reports), or one day/one month (daily and monthly reports) for the interval. For
the action of acquiring data, see sections 8.1 and 8.3.

Saving Data to the External Storage Media

External storage media

Various data can be stored to the following storage media:

• 3.5” floppy disk (1.44 MB, 2HD)

• Zip disk (100 MB)

• ATA flash memory card (4 MB to 160 MB): The size varies depending on the memory
card that you are using.

Overview of Functions

Save method

There are two methods of storing data to the external storage medium. One method
stores the data when the storage medium is inserted into the drive (referred to as manual
save). The other method stores data automatically at certain time intervals to a storage
medium that has been inserted into the drive beforehand (referred to as auto save).

Other types of data that can be stored

In addition to the types of data described in “Acquiring Data to the Internal Memory,” the
following types of data can be stored on the external storage medium.

• Setting data

The RD-MV200 setting data, such as the setting of the functions of the input section
as described in section 1.2, can also be stored to an external storage medium to the
specified file name. The stored data can also be loaded and used by the RD-MV200.

• Image data of the display screen

The image data of the display screen can be stored to the external storage medium.
The image data can be pasted to documents created on a PC.

Saving Data via Ethernet

The display data, event data, and report data, as described in “Acquiring Data to the
Internal Memory,” can be automatically transferred to an FTP server via Ethernet for
storage. Conversely, the RD-MV200 can operate as an FTP server. The RD-MV200 can
be accessed from a PC and the data in the external storage medium can be retrieved
for storage. For these functions, see the RD-MV100/RD-MV200 Communication
Interface User’s Manual (M3643).

displayed on the screen. In addition, a signal can be output from the relay output
terminals on the rear panel of the RD-MV200 (only on models with the optional alarm
output relay function (/AR1, /AR2, /A1, /A2, /A3, /A4, or /A5)).

Alarm indication

The alarm conditions are displayed as alarm icons in the status display section and on
the trend, digital, bar graph, and overview displays. The detailed information about the
alarms is displayed in the alarm summary.
Alarms are displayed when the alarm conditions are met. You can select to clear the
alarm when the conditions are no longer met (non-hold alarm) or hold the alarm until it is
cleared (hold alarm).

1.5 Alarm Function

Alarm hysteresis

This applies to upper and lower limit alarms on measurement channels.
A width (hysteresis) can be specified on the value used to set or release the alarm. This
prevents the alarm from being set or released repetitively when the measured value is
fluctuating around the alarm value. The hysteresis is fixed to 0.5% of the display span
(display scale if the range is set to [Scale]). The initial setting is [ON].

Alarm output relay

If you are using a model with the optional alarm output relay (/AR1, /AR2, /A1, /A2, /A3, /
A4, or /A5), a contact signal can be generated according to the alarm conditions. For the
procedure related to setting the alarm output relay, see section 6.2, “Alarm Setting.”
The following functions can be specified on the alarm output relay. For details, see
section 6.4.

• When multiple alarms are set to one alarm output relay, notify the succeeding alarms
after the first alarm that causes the relay operation (reflash alarm function).

• When multiple alarms are set to one alarm output relay, operate the relay when all
specified alarms are active (AND function)

• Energize or de-energize the alarm output relay when the alarm occurs (energize/de­energize function of the output relay).

• When the alarm changes from the ON state to the OFF state (return to normal
condition), turn OFF the output relay with an alarm ACK operation (output relay hold
function).

1.6 Computation Function and Report Function
(/M1 Option)

You can perform computations by specifying a computing equation and display the
results as computed values of a computation channel on various displays such as the
trend display, numerical display, and bar graph display. You can use data of
measurement channels, data of computation channels, constants, etc. in the computing
equation. Computed data can be saved similar to measured data of measurement
channels. Computation is performed every scan interval. For details on computation
functions, see chapter 11.

1.6 Computation Function and Report Function (/M1 Option)

Report Function

The report function is one of the functions provided by the optional computation function
(/M1).
This function computes the average, maximum, minimum, and sum for the specified
channels at specified intervals and writes the result to the internal memory.
You can select the report type from hourly reports only, daily reports only, daily and
weekly reports, and daily and monthly reports. The reports are created every hour on
the hour for hourly reports, at the specified hour on the hour for daily reports (once a
day), at the specified hour on the hour on the specified day for weekly reports (once a
week), and at the specified hour on the hour on the specified date for monthly reports
(once a month).
For example, in the case of daily reports, the average, maximum, minimum, and sum
over a day for the specified channels are computed at the specified time (on the hour),
and the results are acquired to the internal memory. This constitutes one report data set.
The report data residing in the memory can be displayed on the RD-MV200’s LCD (see
section 1.3, “Display Function”).
In addition, the report data residing in the internal memory can be saved to an external
storage medium (section 1.4, “Storage Function”). Because the report data are saved to
the external storage medium in ASCII format, spreadsheet applications can be used to
view the data (see appendix 2, “Data Format of ASCII Files”).
For details related to the report function, see section 11.11.

and vinyl products to remain in contact with the RD-MV200 for long periods of time.
This may damage the RD-MV200.

RD-MV200, immediately turn OFF the power and unplug the power cord. Then,
contact Omega.

CAUTION

Don’t put any weight on the recorder while it is in reclined position with its front
feet up, as it may damage the feet.

Handling precautions of external storage media

• Take special care in handling external storage media as they are delicate products.
For general precautions, see the instruction manual that came with the external
storage medium.

• Floppy disks and Zip disks may not operate properly under high or low temperature
environment. If you are using the RD-MV200 in a low-temperature environment (less
than 10°C), let the RD-MV200 warm-up for at least 30 minutes beforehand.

• If you are using them in a high-temperature environment (greater than 40°C), we
recommend the external storage medium be inserted into the drive when saving the
data and be removed after the data have been saved (manual save, see section 8.4).

• Remove the external storage medium from the drive when turning ON/OFF the RD­MV200.

• Do not remove the external storage medium while the access lamp is lit. Doing so
can destroy the data on the medium.

• If you are using the compact flash card on RD-MV200s with the ATA flash memory
card driver, be careful of the static electricity. The RD-MV200 may not operate
properly, if you touch the compact flash card that is inserted into the recorder when
there is static electricity on your body.

Don’t expose the floppy disk drive or Zip drive to vibration or shocks, as it may
damage the drives.

CAUTION

2-1

2.2 Installing the RD-MV200

Installation location

Install the RD-MV200 in a location that meets the following conditions. See also the
normal operating conditions described in section 14.7, “General Specifications.”

For safety reasons, don’t mount the recorder with the back panel downwards.

• Instrument panel or rack

The RD-MV200 is designed for panel or rack mounting.

• Well-ventilated location

To prevent overheating, install the RD-MV200 in a well-ventilated location.
A space of 50 mm or more from the right, left and top surface of the RD-MV200 is
recommended.

• Minimum mechanical vibrations

Choose an installation location with the minimum mechanical vibration.

• Horizontal

Install the RD-MV200 horizontally. (However, the RD-MV200 can be inclined up to
approximately 10 degrees backwards when the font feet are up)

Note

• Condensation may occur if the RD-MV200 is moved to another place where both the ambient

temperature and humidity are higher, or if the temperature changes rapidly. In addition,

measurement errors will result when using thermocouples. In this case, let the RD-MV200

adjust to the new environment for at least one hour before using it.

• The lifetime of the LCD may be shortened if the RD-MV200 is used in a high-temperature

environment over a long period of time. When installing the RD-MV200 in a high-temperature

environment (greater than 40°C), we recommend the backlight brightness of the LCD be set

to a low setting. For setting the LCD brightness, see section 7.14.

CAUTION

2-2

Do not install the RD-MV200 in the following places:

• In direct sunlight or near heat sources

Install the RD-MV200 in a place with small temperature fluctuations near room
temperature (23°C). Placing the RD-MV200 in direct sunlight or near heat sources
can cause adverse effects on the internal circuitry.

• Where an excessive amount of soot, steam, moisture, dust, or corrosive gases
are present

Soot, steam, moisture, dust, and corrosive gases will adversely affect the RD-MV200.
Avoid such locations.

• Near strong magnetic field sources

Do not bring magnets or instruments that produce electromagnetic fields close to the
RD-MV200. Operating the RD-MV200 in strong magnetic fields can cause errors in
the measurements.

• Bad angle for viewing the screen

Because the RD-MV200 uses a 10.4” TFT color LCD, it is difficult to view the display
from an extreme angle. Please install the RD-MV200 so that the monitor can be
viewed from the front.

2.3 Input Signal Wiring

If a strong tension is applied to the cable wired to the RD-MV200, the terminals
of the RD-MV200 and/or the cable can be damaged. Allow extra wire for the
input signal wire so that direct tension is not applied to the input terminals of the
recorder.

Precautions to be taken while wiring

Take the following precautions when wiring the input signal cables.

• It is recommended that crimp-on lugs (designed for 4 mm screws) with
insulation sleeves be used on the lead wire ends. However, this does not apply
to the clamped terminals (the suffix code for “input terminal” is “-1”).

Crimp-on lug

• Take measures to prevent noise from entering the measurement circuit.

• Move the measurement circuit away from the power cable (power circuit) and

ground cable.

• It is desirable that the item being measured does not generate noise. However, if

this is unavoidable, isolate the measurement circuit from the item. Also, ground the
item being measured.

• Shielded wires should be used to minimize noise caused by electrostatic induction.

Connect the shield to the functional ground terminal as necessary (earth ground
the functional ground terminal, make sure you are not grounding at two points).

• To minimize noise caused by electromagnetic induction, twist the measurement

circuit wires at short, equal intervals.

• Make sure to earth ground the protective ground terminal through minimum

resistance (AC power supply models, less than 100 Ω).

CAUTION

Before Using the RD-MV200

• When using internal reference junction compensation on the thermocouple
input, take measures to stabilize the temperature at the input terminal.

• Always use the input terminal cover.

• Do not use thick wires which may cause large heat dissipation (cross sectional

area 0.5 mm

• Make sure that the air temperature remains reasonably stable. Large temperature

fluctuations can occur if a nearby fan turns ON or OFF.

• Connecting the input wires in parallel with other devices can cause signal
degradation, affecting all connected devices.

If you need to make a parallel connection, then

• Turn the burnout function OFF (See section 5.9).

• Ground the instruments to the same point.

• Do not turn ON or OFF another instrument during operation. This can have

adverse effects on the other instruments.

• RTDs cannot be wired in parallel.

Starting the waveform display of the trend display/stopping the waveform update

The operation procedure used to start the waveform display of the trend display and the
procedure used to stop the waveform update are the same as the operation used to
start/stop the data acquisition to the internal memory. When the data are being acquired
to the internal memory, the waveform is displayed. When it is stopped, the waveform is
not updated. For the operating procedure, see sections 8.5 and 8.6.

4-10

Note

• Trend screen when the acquired data type is set to “Event only” on the RD-MV210/RD-

MV220/RD-MV230 models with the computation option (/M1)
If the screen is switched from the trend screen to another screen back to the trend screen, the
old waveform is cleared and the waveform from that point is displayed. This is due to the
memory capacity restriction of the internal memory and is not an abnormal behavior. The
acquired data are kept in the internal memory.

• When waveform updating is stopped, the waveform at that point remain displayed on the

screen.

4.3 Using the Trend, Digital, and Bar Graph Screens

Explanation

About group display and all channel display

The group display of trend, digital, and bar graph and the all channel display of the trend
are displayed in the following fashion (see table below). They depend on whether
channels are assigned to the groups and whether the channels are set to display the
trend and set to store the data.

• The numerical display of trend, digital, and bar graph displays and the bar graph
display are updated at all times when they are displayed. It is not affected by
whether or not the waveform of the trend display is shown.

• The waveform of the trend display is updated at the display update rate. For the
procedure related to setting the display update rate, see section 7.3, “Setting the
Display Update Rate (Trend).”

• For the procedure related to setting the channel to display the trend and to store the
data, see section 8.10.

• For the procedure used to assign channels to groups, see section 7.6.
