Functions & Configuration

Brand: IWATSU Origin: Japan

A lineup of three new general-purpose counters with high cost-performance, featuring easy one-key-one-action operation, user-friendly display guidance, and calculation functions to support any application.
The SC-7207/SC-7206/SC-7205 universal counters provide complete functions including frequency, period, time interval, pulse width, phase, frequency ratio, duty cycle, event accumulation, and peak voltage measurement, with simple operation. They are suitable for R&D and technical training as basic measuring instruments, as well as for production/inspection lines.

One-touch simple operation
Easy-to-read fluorescent indicator tube provides detailed 5x7 dot display
Auto trigger function eliminates trigger level setting - trigger level can also be set manually
Comparator and statistical calculation functions easily improve the efficiency of production line inspection operations
Capable of unit conversion (revolutions, speed, etc.) using the scaling calculation function
Easily check the waveform amplitude when measuring the peak voltage of the input signal
Panel setting save/recall function helps improve the efficiency of inspection procedures
Full remote control via standard GP-IB (SC-7205 option SC-701) or RS-232C interface
Options provide extensive expandability
