(r/s is the numerical value obtained when the r/min measurement value is divided by 60)

Measurement accuracy Displayed value* x (±0.02%) ±1 count
* The displayed value is the count value excluding figures after the decimal point.
Memory function 20 data (MAX)
Over-range function The over-range alarm (ERROR mark) is displayed when the measured value exceeds the display range.
Rotation upper limit alarm function The upper limit alarm ( mark) is displayed when the number of rotations exceeds the preset upper limit value.
Sensitivity adjustment function A rotary dial at the right-hand side of the device is used to adjust the sensitivity.
Analog output
