Models A2102 and A2102/LSR features and operation

Optical systems - Two types of optical system are used: -

Model A2102 has the standard visible light source via an incandescent Minilamp

Model A2102/LSR has enhanced optical Laser light system for greater optical performance.

Both models have a fully autoranging measurement system as standard.

Optical rpm measurement

1.Ensure the machine to be measured is in a safe off mode.

2.Attach small reflective target to machine shaft (typically 6mm x 25mm.less for laser).

3 Start machine and point the Tachometer at the target.

4.Press and hold continuously either of the On/Off buttons to suit application.

5.Aim light beam onto target, ensure "on-target" sign is glowing or flashing steadily.

6.Read rpm, releasing button will hold last reading in the display for 1 minute.

7.Press either On button to zero reading or take another measurement.
