data
[Flexible Recording]
The VR200 uses a 3.5-inch floppy disk as the recording medium instead of recording paper used in conventional recorders. Recording of data in electronic
form allows versatility in recording (file) formats.
Versatile file formats
Event recording for a wider range of applications
The VR200 has two file formats for measurement data, a display data file and an event file. The features of each are set out
below.
1. Display data file ... A file for observing long-term trends
The VR200 can perform event recording (saving data in an event
file) using a trigger, to permit a detailed analysis of measurement data in the event of an alarm or other trouble. Needless
to say, you can set a pre-trigger as well, enabling you to analyze the data before and after the trigger.
The data save period is directly proportional to the analog waveform span rate (selectable from 1, 5, 10, 20, 30, and 60 min/
div). The maximum and minimum values of data measured
every 125 ms(fastest 1s for 6-ch model) are saved for the duration of the data save period.

Desired application
Universal Input Handles Any Signals.
I want to record the bearing temperature of the turbine of an electrical generator. Normally, I want to obtain data at 1-minute intervals, and in addition I wish
to perform a detailed analysis of the data obtained for a 5-minute period when
the turbine is being started up and also when it is being shut down, twice a day.
The input signal can be selected arbitrarily from a DC voltage,
thermocouple, resistance temperature detector, and event
recording (DI on/off status) for each channel.
The calculated data can be viewed on a personal computer.
Save the data obtained under normal conditions in a display data file using a
display span rate of 30 minutes/div (6 channels’ worth of data can be saved for
a period of about 33 days).
Save the data obtained when the turbine is being started up and also shut
down in an event file divided into 16 parts, using a remote contact as a trigger
and 1-second sampling intervals (6 channels’ worth of data can be saved for a
period of about 20 minutes in one of the divided files).
values (of data measured in the measurement period) over a period of 60 seconds
are saved, and the data displayed (updated) as a waveform every 60 seconds.
Turbine bearing temperature
2. Event file ... File intended for analyzing data in detail
All data is saved at the specified sampling intervals (selectable from 125 ms, 250 ms, 500 ms, and 1s for 2,4-ch model,
and 1, 2, 10, 30, 60, and 120s for 6-ch model).
You can combine these two files in the following ways to suit
the particular application.

Mathematical Functions
Various optional Mathematical functions allow calculated values
such as totalized flow rates to be displayed as trend graphs or
digital values, and to be saved to a floppy disk. The data of
each channel, regardless of whether a measured value or
calculated value is assigned to it, can be saved as binary data
at set intervals (1 minute to 24 hours). The calculated data
can thus be easily viewed and manipulated on a personal
computer.*

Optional Large Memory
For long-term data storage, the internal memory can be
expanded, which is useful when using the mathematical
functions or when using the VR200 for data acquisition at
monitoring stations that are left unmanned for a long time. The
data stored in the expanded memory is saved to three floppy
disks for the 4-channel model, and four floppy disks for the 6channel model. The following shows examples of sampling
times when the optional large memory is installed.
[True Reliability Is Born of Technical Genius]
