- A rotary speed ratio meter that inputs 2-channel signals from rotation pulse output sensors and calculates the speed ratio between channels.
- Can also function as an individual tachometer for each channel based on settings.
- Features comparator output as standard, with optional analog and digital outputs available.
- Ideal for experimental equipment and factory production lines.

Supports NPN open collector, AC signals, TTL, line driver, and more.
Can be connected to magnetic gear speed sensors, electromagnetic pickups, flow sensors, rotary encoders, motor drivers, etc.
Time average and moving average parameters can be configured as desired according to measurement conditions.
The display can switch between individual channel speeds and speed ratio/percentage updates.
Delivers voltage output from 0 to 10 V for speed ratio, and -10 to +10 V for speed percentage.
By switching modes, analog output (0 to 10 V) proportional to each channel's speed can be extracted with up to a 1ms refresh rate.
