Realization of various analytical display combinations without using a PC
The primary display has multiple displays, such as numerical displays, trend charts, histogram charts, and arc scale meters. For each primary display, there are also many secondary displays, so various screen combinations can be selected according to measurement needs.
A new display that makes further use of the judgment function
The large display has been made easier to see.
You can also see the display from a long distance. The device is popular because adjustment work is easy and quick.
Unique needle display. Analog changes are simulated in digital.
In addition to being useful for judging approximations, it can be used in a variety of ways in conjunction with the judgment function. The color of the needle changes when the judgment criterion is exceeded.
Easy to use
Quick Launch
The measurement can be started immediately by setting the setup information when the power is turned on.
The instantaneous log memory of the screen can be saved
Screen copying can be completed in two actions. The measurement state and the measurement conditions are not related at all. You can copy the screen with two keystrokes when you need to. This function is very useful during busy measurement work without the need for troublesome settings.
(VOAC7602 only)
Large capacity 100k readings logging memory
With the large memory, you can retrieve more than 24 hours of 1-second data with a timestamp. It is also always logging, so you will not forget to save data.
Logging is possible for a long time with the long memory
It has a data size of 100k points and supports long-term logging. Example) If the sampling rate is 1 time per second, you can log for more than 1 day.

[Continuous write function to USB memory device] Long time logging possible
In the past, it was possible to manually save data to USB using the internal memory of the main unit, but with the new function, it is now possible to continuously save measurement data to the USB memory device while measuring.
This is useful when obtaining data for long periods of time with relatively slow measurement cycles. For example, 1S/s cycle measurements can be continued for more than 1 year.
Extending secondary statistical operations
Extended from the conventional σ = 1σ to 3σ to σ = 1σ to 6σ, making it possible to distribute more widely.
Bulk mode in acquisition-only mode 30kS/s
Bulk mode focuses on retrieving measurement data. During data acquisition, the on-screen measured data is turned off to ensure an accurate sampling rate of up to 30k samples/s. The measurement data is stored in the log memory and can be displayed in trends and histograms using the offline browsing function. You can also save the data to a USB flash drive.

Pre-trigger function to enable the use of log memory
n the bulk mode of VOAC7602, capture can be stopped by setting the level of the measured value, the result of the LIMIT judgment, or an external trigger, etc. to a stop event. This makes it possible to retrieve the data before and after the event of interest in the same way as the pre-trigger in an oscilloscope. In addition, by utilizing the large capacity of 100k readings, it is possible to capture data for long periods of time with high resolution even during high-speed sampling. In addition, you can accept stop events as soon as you start logging, so that even when the sampling rate is slow, you do not have to wait for the trigger-inhibit time like an oscilloscope, and the acquisition time is minimal.
Offline histogram chart display to help you measure yield
The data captured in the log memory can be displayed in a histogram, and yield can be easily measured by cursor operation. Although it is a function that designed to be analyzed by a PC, it can be judged on the spot, so you can expect a significant improvement in work efficiency.
The frequency of data points inside the cursor range is displayed as a percentage (%) of the total. The horizontal axis serves as a reference for judgment, such as by indicating voltage, so the percentage versus the criterion can be intuitively grasped.
Offline trend chart showing the time change of the measurement.
In addition to displaying like an oscilloscope, statistics can be recalculated depending on the range of the cursor, so that the required range of statistics can be obtained. The screen can be copied to the USB memory device, a useful feature for further improving work efficiency.
Significantly upgraded judgment function
The VOAC7602 can perform advanced analysis based on the results of LIMIT judgment. The feature is that this can be done with easy operation. The device provides a clear answer to the question that most troubles technicians taking measurements: how much failure has occurred and when did it occur?
This is the screen that solves “How much failure has occurred?”
This is the screen that solves “When did the failure occur?”
Easy extraction of required parts with offline cursor function
Trigger functions to meet various needs
Interval trigger function
The specified number of times is measured at a constant time interval.
Measurement using the trigger delay function
You can set the delay time from the trigger input to the first data measurement. You can delay the measurement timing of production equipment, etc., and wait for the measurement to stabilize before measuring.
The following performance specifications are based on the conditions and definitions below.Warm-up time: 1 hour, Temperature/Humidity: 23°C ± 5°C, 80% RH or less, 1-year accuracy, Response time: Time required to reach the specified accuracy within each range.
