An isolated input system has been implemented to enable worry-free measurement. Ten input channels have been provided to meet multichannel needs.
M4 screw terminals have been used for the input terminals to simplify wiring. The terminals can be tightened easily with a screwdriver. If an abnormal value arises, the alarm function informs the operator of the abnormality. Alarm output terminals for four channels are provided as standard.
Humidity measurement can be performed by connecting the dedicated humidity sensor to an analog terminal on the MT100 unit.
A USB memory stick is used for the recording medium. A large volume of data
measured over a long period of time on the ten available channels can be directly
written to and stored on the memory stick. The MT100’s internal memory consists
of 14-MB flash media.
| Capture interval (sampling speed) | 100ms | 1s | 10s | 1min |
|---|---|---|---|---|
| 14-Mbyte internal flash memory | Approx. 13 hours | Approx. 5 days | Approx. 53 days | Approx. 323 days |
| USB memory stick (256 Mbytes) | Approx. 9 days | Approx. 98 days | Approx. 987 days | Approx. 5,925 days |
The USB memory stick can be removed* even while long-term recording is being performed to enable checking of measurement that is still in progress. If the USB memory stick is removed, data capture is switched to the MT100’s internal buffer memory for a period of approximately 10 minutes. When the USB memory stick is reinserted in the MT100, data is once again captured to the memory stick.
In order to withstand severe field environments, the structure has been designed to be dustproof, moisture-proof, and vibration-resistant. The front panel of the MT100 unit is an IP65-compliant structure that is both dustproof and moisture-proof. To prevent the penetration of dust, there are no slits in the MT100 unit itself. In addition, the unit’s vibration-resistant structure complies with the Vibration Testing Methods for Automobile Parts Standard, Type 1 Class A.
Moreover, the space-saving design offers a reduced depth of only 200 mm to enable easy installation in various types of test systems.
A large-format 5.7-inch color
TFT liquid crystal display,
bright and easy to read, is built-in.
The measurement results are
faithfully reproduced in the display formats used by conventional analog recorders. Waveform
displays that are similar to those of pen recorders or dot-printing recorders enable the measurement
progress to be easily ascertained at a glance. Four display formats are provided to enable the
most easy-to-view format to be selected for each measurement application.
A compressed display of the time axis is provided at the bottom of the screen.
As with a pen recorder or a dot-printing recorder, the waveform display enables
the measurement progress to be easily ascertained at a glance. The compression
ratio can be set in ten increments within the 1/10 to 1/100 TIME/DIV range.
A diverse range of network functions can be used to suit the measurement application.
WEB server functionWaveform display and MT100 settings can be made via a web browser such as Internet Explorer.
|
FTP server functionData stored in the MT100’s internal memory or the USB memory stick can be transferred or deleted through operations performed at the computer.
|
FTP client functionThe data captured to the MT100’s internal memory or the USB memory stick can be automatically backed up to the FTP server at fixed intervals.
|
NTP client server function
The MT100’s time can be synchronized to the NTP server’s time at periodic intervals.
|
The application software provided as a standard accessory with the
MT100 enables easy online measurement and conversion of the data file format.
Icon keys have been provided for intuitive waveform operations.
The number of setting screens has been reduced to only six. Settings in the amp setting screen and other screens can be performed while viewing the input signals.
Y-T, X-Y, Digital display, Meter display, and Report display screens have been
provided to suit various measurement applications. In addition, the Replay
display screen can be specified as Y-T, X-Y between cursors or Digital display.
