Using the high-resolution LCD screen, you can view the measured values while watching the average, the maximum and the minimum values. Moreover, VOAC7602 enables you to observe the statistical values while viewing the Trend and the Histogram charts. Other than those above, there are various kinds of combinations of displays available to be shown aside and these can be chosen from many functions, such as LIMIT function, and Analog meter display, which is effective for analog judgment.

Quick saving of log memory on the screen

簡単ハードコピー操作

You can store the log information in USB memories by a simple operation. No difficult settings are required and this is useful when you have to perform a lot of measurement.

 

Quick start-up

If you store your configurations into internal memory, you can start your measurement immediately as you can bypass setting configurations again.

Large capacity :100k data memory for logging

大容量メモリ保存

Thanks to the large memory, you can store data with timestamps for more than 24 hours even if you measure once a second. The equipment always keeps logging. You won’t miss any of the data.

Digital Multimeter VOAC7602            Function

"BULK mode" 30kS/s (New)

The measurement in the BULK stops the other functions than measurement data acquisition when measurement is done. Therefore, logging can be done while ensuring the sampling rate of up to 30kS/s. The measured data is kept in log memory, and Trend chart and Histogram chart can be displayed by offline browse function. The data can be stored in a memory as well.

30kS/sを保証

Pre-trigger function utilizing log memory effectively (New)

VOAC 7602's bulk mode can stop loading levels of measurement values, LIMIT judgment result, External trigger, etc. , by setting "Stop Event". This triggering can be used in similar way to oscilloscopes' pre-trigger function. You can focus on data taken around when the event occurred. In addition, as log memory has 100k readings, a long time data can be loaded with high resolution at high speed sampling. Moreover, As this multimeter can accept "Stop Event" just after start of the logging, you do not need to wait for the time which inhibits the trigger even if sampling rate is low. So, the loading time will be minimized.

プリトリガ機能

A long time logging is available with long time memory.

VOAC7602 has a large memory, which can store the log for up to 100k points.
Example: Logging more than one day is available when sampling rate is 1 time/sec.

Offline/Histogram chart display, being useful for Yield ratio measurement (New)

Display the data loaded into the log memory in a histogram chart, so that you can measure the yield rate easily by cursor operation.
So far this rate was calculated by PC, this will improve your work efficiency at significant level. The LIMIT  judgment can be performed on site.

ヒストグラム表示画面

 

The number of times within the ranges specified by cursors, and the ratio will be displayed in percentage figures (%).
Since indexes suitable for the basis such as voltage can be set as x-axis, you intuitively understand the ratio of acceptance/rejection criterion.

Offline-Trend chart display: Temporal alteration of measurement value shown (New)

Besides the display function such as an oscilloscope’s, the function to recalculate the statistical data within the cursor range will help you get the statistical data for the range you need. As you can save the display data in USB memory, this function will improve working efficiency furthermore.

Highly-improved LIMIT function New)

VOAC7602 can perform the advanced analysis based on the result of LIMIT function, and this will be performed by easy operation. This product gives you clear answers to your most difficult questions such as how many troubles happened, when they happened and so on.

The right figure gives the answer to:

Various kinds of trigger functions to meet market needs

Interval trigger function

トリガ機能1

This function repeats measurement at fixed time interval until such measurement is performed certain times specified in advance.

   

Trigger delay function

トリガ機能2

This function let you set the delay time from the trigger input to the first data measurement. You can delay the measurement timing of the production facilities and measure the data after the facility become stable.
