1.3 Functions of the Main Module
Measurement
Measured data sampled at certain intervals is acquired by the various input modules.
Acquired data is stored in internal memory. During recording, acquired data is saved to
the CF card according to the settings.
In addition, if an alarm occurs or if the main module receives output commands sent from
the PC, the main module generates signal output instructions to the output modules.
Data Sampling
The relationship between the measurement interval and recording interval is as follows:
The measured, computed, or thinned data that is recorded at the recording interval is
saved to the CF card.

Measurement Intervals
• Synchronization between modules
If set to the same measurement interval, measurements made by input modules in the
same acquisition unit are synchronized.
• Synchronization between channels
On the 4-CH, High-Speed Universal Input Module, the 10-CH, Pulse Input Module,
and the 10-CH, High-Speed Digital Input Module, measurement is synchronized
between channels.
On the 10-CH, Medium-Speed Universal Input Module, 30-CH, Medium Speed
DCV/TC/DI Input Module, Six-Channel Medium-Speed Four-Wire R
TD Resistance
Input Module, and 4-CH, Medium-Speed Strain Input Module, measurement is not
nchronized between channels since measurement occurs sequentially by channel (it
sy
can be said to be synchronized within measurement intervals).
Measurement Groups
Three measurement intervals can be set, and measurement channels can be assigned
to each interval. There is a particular order in which measurement intervals can be set to
measurement groups.
For a description of setting the measurement interval, see section 3.4, “Setting Acquisition
Conditions for Measured/Computed Data.”
A first-order lag filter is available. You can select a time constant (time until 63.2% of
the output value is reached) corresponding to the measurement interval indicated in the
equation below.
T
ime constant = measurement interval × N (where N = 5, 10, 20, 25, 40, 50, or 100)
For details on filters, see section 2.9, “Measures Against Noise on the MW100 Data
Acquisition Unit.”

Linear scalingScale
Note that the channels included on the 10-CH Pulse Input Module are only available for
integration (TLOG.PSUM).
Expressions using measured and computed data as variables can be entered and
executed on channels dedicated for computation, and the results can be displayed and
saved. Computations are executed every measurement interval (shortest interval is 100
ms).
For details, see section 1.15, “MATH Functions (/M1 Option).”
Explanation of Functions
Report Function (/M3 Option)
You can perform statistical computations on measurement or MATH channel data
and display and save the results. The types of reports are hourly, daily, weekly, or
monthly. Reports can be created using the maximum, minimum, average, integral, and
instantaneous values from up to 60 channels.
For details on the report function, see section 1.16, “Report Function (/M3 Option).”
Remote RJC (RRJC)
When the item to be measured is located at a great distance, you can set up relay
terminals near the item, measure the temperature difference between the relay terminal
and the input terminal of the input module (reference channel) using thermocouples,
and use the resultant electromotive force as the reference junction compensation of
the temperature measurement. By connecting a copper wire between the relay terminal
and input terminal of the input module, and a thermocouple between the DUT and relay
terminal, you can measure the temperature of the DUT without the need for a large
amount of expensive thermocouples.

1.3 Functions of the Main Module
Range Over
When the MW100 detects a range over (see below) on a measurement or MATH
channel, “+Over” or “–Over” is displayed.

over is detected if the value that is measured on a measurement channel is outside
of the measurable range by more than ±5%. For example, when the measurement
range is 2 V
2.2000 V or goes below –2.2000 V, a range over is detected.

temperature goes more than approximately 10°C above or below the measurable
range. For example, when the measurement range is set to R, the measurable
range is 0.0 to 1760.0°C. If the temperature exceeds 1770.0°C, “+Over” will be
displayed. If the temperature goes below –10.0°C, “–Over” will be displayed. The
special ranges mentioned here are ranges such as KpvsAu7Fe or J263. If you
are using a special range, “–Over” will be displayed if the temperature goes below
approximately 0°C.

will be handled as a range-over value.
