WARNING

Power Supply

Ensure the source voltage matches the voltage of the power supply before
turning on the power.

Power Cable and Plug (for Desk-top Model)

For the power cable, use those provided by Omega to prevent fire and electric
shock.
Connect the power cable of the VR recorder to a 3-pole power socket with a
protectibe grounding pole.
Do not use an extension cable without a protective grounding wire, since this
invalidates the protection.

Protective Grounding

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

Necessity of Protective Grounding

Never cut off the internal or external protective grounding wire or disconnect the
wiring of the protective grounding terminal, since doing so creates the risk of
shock.

Defective Protective Grounding and Fuse

Do not operate the instrument if the protective grounding or fuse might be
defective. Before operating this product, check that there is no defect in the
protective grounding and fuses.

Fuse

To prevent a fire, use the fuse of the specified standard (current, voltage, type).
Before replacing the fuse, turn off the power and disconnect the power source.
Do not use a different fuse nor short-circuit the fuse holder.

Do Not Operate in an 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.

Never T ouch the Interior of the Instrument

Inside this instrument there are areas of high voltage; never touch the interior if
the power supply is connected. This instrument contains parts which can be
adjusted inside; however, internal inspection and adjustments should be done
by qualified personnel only.

External Connection

To ground securely, connect the protective grounding before connecting to a
measurement or control unit.

Waveform Span Rate

The waveform(s) moves along with the time axis at a speed determined by the
waveform span rate. The waveform span rate, which is equivalent to the chart speed in
a conventional pen recorder and which determines the time span in each division (grid
interval) of the time scale, can be selected from six rates as shown in the following
table. To trace the waveform on the screen, the maximum and minimum values of the
measured values, which are sampled at the measurement period* within the interval
equivalent to one pixel of the time scale, are handled as the data to be traced on that
time-axis pixel. *The measurement period is 125 ms for the VR202/VR204, and 1 s or
2 s for the VR206. The following table shows the relation between the waveform span
rate and trend speed.

The updating period of the digital indications at the top of the screen is fixed to one
second, regardless of the above. However, for the VR206, it is fixed to two seconds if
the measurement period is set as two seconds.

Operation Functions on Screen

The following operation functions are provided on the screen.

Function Description

Referencing past trend data Past trends stored in the internal memory are displayed on the left half of the

screen. All data stored in the internal memory can be viewed by scrolling
the screen.

Magnifying/reducing the time axis In addition to the normal trend screen determined by the waveform span

rate, the display span (= 8 divisions) can be switched to 8, 24, or 40 minutes
to magnify/reduce the time axis of the trend graphs.

Writing time-axis marks Time-axis marks can be displayed on arbitrary points on the time axis. The

information at the points of time thus marked is stored in the internal
memory as time-axis mark information.

1.1.4 Data Storage Functions

Data Storage Action

For storing data, this recorder has 1 MB (for VR202/VR204) or 1.44 MB (for VR206)
of internal memory and is equipped with a 3.5-inch floppy disk drive (1.44 MB 2HD for
DOS). (Floppy disks formatted as 1.2 MB 2HD can be used only for the VR202/VR204
for users of an NEC 9800 series PC with Japanese-version OS (DOS/V).) The
measured data are always stored in the internal memory. Once the floppy disk is
inserted, the recorder starts copying the measured data from the internal memory to the
floppy disk automatically, together with the following data.

• Major setup parameters

• Information on time-axis marks, power failures, and alarms

Data Types

The table below shows the data types and contents which are saved on FDC.

Collection of Event Data

The processing which occurs when collecting the event data is determined by

• File definitions (types and number of files defined);

• Sampling period; and

• Trigger action type (in the sample mode).

1.1 Functional Overview

The following table shows the selections available for these specifications.

Definition Description

File definitions The typ es and num ber of files to be created can be selected from the

following three combinations.
(a) Event file + display data file

One event file and display data file for each are created.

(b) Event file x 16 + display data file

This combination can be selected only when the sample mode is set to
trigger-on or trigger-rotation (see the second next row). Sixteen event
files, in which the measured data are to be stored after the trigger is
raised, are created together with one display data file.

(c) Event file only

Only one event file is created.

Sampling period The sample period at which to store the data can be selected from:

VR202/VR204: 125 ms, 250 ms, 500 ms, or 1 s
VR206: Fast, 2 s, 10 s , 30 s, 60 s, or 120 s

Sample mode The trigger action can be selected from the following three types. When

“trigger-on” or “trigger-rotation” is selected, various other trigger settings
can be made.
Trigger-free: Data collection starts after power-on. When the file in

the internal memory becomes full, the data are
overwritten.

Trigger-on: Data collection starts when a trigger is raised. When the

file in the internal memory becomes full, the data
collection stops.

Trigger-rotation: Data collection starts when a trigger is raised. After the

file in the internal memory becomes full, the data are
overwritten.

1. OVERVIEW OF VR200

Relation Between Measuring Period and Sampling Period

This recorder captures the input data into its A/D converter at the measuring period
shown below. The sampling period denotes the interval used to sample and store the
measured data in memory. If the sampling period is set to the same value as the
measuring period, all measured data values are stored in the memory.

Measuring period:

VR202/VR204:125 ms
VR206: 1 s (when the A/D integration frequency is set as 50 Hz, 60 Hz, or

“AUTO”)
2 s (when the A/D integration frequency is set as 100 ms)

Trigger

This recorder is usually used such that, upon power-on, it runs the self-diagnostics and
then automatically starts data collection into the memory. However, this recording
action can be set to be suspended upon power-on and started by a certain key. This key
is called the trigger. There are three types of triggers that can be set for this recorder.
Key trigger: Pressing the key starts data storage.
External trigger: When the contact input signal is closed, data storage starts.
Alarm trigger: When a specified alarm occurs, data storage starts.
The pre-trigger function, which means that data is always collected in the leading part
of the event file, is useful when data needs to be collected before the trigger occurs.

j. Grid

Grids are displayed at intervals corresponding to the specified number of divisions
for the scale axis and at the waveform span rate for the time axis. The grid moves
together with the trend graph.

Note

The grid lines of the time axis are usually displayed at every interval of the selected waveform span rate. However, if the power
is switched off and on during the measurement, the trends (waveforms) start to be traced again continuously from the point of time
of the power-off and this causes the interval of the grid lines to be different from the waveform span rate in this case.

k. Display of Remaining Time Before Overwriting Measured Data (or Re-

maining Time Until Memory Becomes Full If Sampling Mode Is Set As
Trigger-on)

If the sampling mode is not set as trigger-on:
This field displays the remaining time until the measured data start being overwritten
after saving data to an FDC. When the data are saved to an FDC, the displayed time
is reset. If the entire data storage memory is used for one event file, no information
is displayed while the recorder is waiting for the trigger. The remaining time is
displayed as ‘MEM=99hour,’ which then shows the time in minutes when the
remaining time is less than one hour. When the display shows ‘MEMORY FULL,’
the measured data is currently being overwritten.
If the sampling mode is set as trigger-on (and if the entire data storage memory is
used for one event file):
This field displays the remaining time until the memory becomes full; however, no
information is displayed while the recorder is waiting for the trigger. When the
memory becomes full, data sampling to the memory stops.

l. Waveform span rate

Displayed only during the horizontal display of the trend display. You can set
whether or not to display the waveform span rate in the SET mode.

keys are used for data entry and, in the SET and SETUP mode, the functions pictured on
the right of (not “on”) the individual keys are valid.
