Lutron Electronics DT-2230 Operation Manual Download Page 3

1. FEATURES

* Compact and pocket tachometer.
* The best Tachometer in the world. 2 in 1,  one

instrument combine Photo tachometer and Contact
Tachometer.

* Photo tachometer uses Laser light detecting source,

long measuring range up to 1.5 meters, it is useful in
the RPM measurement application where the machine
would be a risk to the operator or close access is
difficult or not possible.  

* Wide measuring range from 0.5 to 100,000 RPM, 0.1

RPM resolution for the measured value  < 1000 RPM.

* Microprocessor based circuit, crystal time base, high

precision with 0.1% accuracy. 

* High visible LCD display gives RPM reading exactly

with no guessing or errors & saves battery energy.

* Memory with recall function, the last value, max., value,

min. value will be stored into the memory automatically.

* The use of durable, long lasting components, including

a strong, light weight ABS plastic housing, assures
almost maintenance free performance for many years.

* RS232 PC serial interface.
* The tachometer have patent patented, refer page 10.
