To use the functions described below, you need to update your firmware for VOAC7602 to the latest version.

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

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

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.

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.

Besides the display function such as an oscilloscope’s, the function to recalculate the statistic 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.

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: 判定機能表示1
"How many troubles happened"

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.
