IWATSU VOAC7602/7502 6.5-digit digital multimeter with data logger

Digital Multimeter VOAC7602

New display enables more flexible use of the judgment function

6½-digit display
High-resolution 4.3-inch (109 mm) LCD
Up to 30 kSa/s sampling rate

Large, easy-to-read screen

4.3-inch (109 mm) high-resolution LCD

Japanese-made high-resolution LCD. Bright with a wide viewing area—its advantages are clear once you use it. Numerals can be displayed in either standard (sans-serif) or seven-segment font. The background color can also be set to one of two modes (white/black).

Various analysis display combinations without a PC

Main displays include numeric values, trend charts, histograms, and arc-scale meters, each with a rich set of auxiliary displays, so you can choose the screen combination that suits your measurement needs.

New display enables more flexible use of the judgment function

Large on-screen readouts are easy to see at a glance.

Visible even from a distance. Highly rated for convenience in adjustment work and other tasks.

Unique pointer display. Analog-style variation shown via digital virtual display.

Beyond basic judgment, it supports a variety of uses combined with the judgment function.
When a judgment threshold is exceeded, the pointer color changes.

Easy-to-use controls

An illumination signal that lights up when needed. Enables quick and intuitive input of values, characters, and symbols required for settings, as well as list selection. Turn and press the knob to confirm the setting.

Instant screen capture to the record memory (VOAC7602 only)

Copy the screen in just two steps.
Regardless of measurement status or conditions.
When needed, two button presses capture the screen. No complicated setup—an invaluable feature during busy measurement work.

Fast startup

Once SETUP information is configured at power-on, measurement can begin immediately.

Large 100k reading record memory

The large-capacity memory captures timestamped data for over 24 hours at 1 sample per second.
Continuous recording also means no missed captures.
