General features
Compact Instruments A2109 tachometers feature a large vertical LCD display that gives excellent visibility in
most applications. Both have an "Inverting display feature" which maintains the display in the correct plane for
the user, for example when pointing the unit down into machinery.
This inverting display feature offers greater operational flexibility in almost any application where access is
difficult.
Laser optics provide enhanced optical performance compared to standard non-contact tachometers. Both mod-
els are supplied with a contact adaptor for rpm and linear speed contact applications.
Other features include Maximum and Minimum speed Capture and Average speed modes.
SAFETY RECOMMENDATIONS
Always read and follow the operating instructions for use.
The units use a laser diode with an output power below 1 mW.
Never stare directly into the laser source.
Never aim the laser beam into anyone else's eyes.
Never open the instrument and attempt to adjust the output of the laser.
All repair work should be taken care of by Compact Instruments repair shop.
