9773 Optical Tacho Adaptor

Description

The 9773 optical tacho adaptor that provides an interface to allow Time Electronics

multifunction calibrators to calibrate virtually all optical tachometers. It is primarily

designed for use with the 5025 and 5051 models.

A high brightness LED can be driven from either of two sources; the 10 MHz digital

frequency output or the main output terminals when AC voltage is selected.

EasyCal procedures can be quickly written to produce calibrations certificates

showing the tachometers accuracy at any desired RPM.

The drive requirements when used with either the 5051 or the 5025 are the same;

2 to 5 V RMS within the frequency range 0.1 Hz to 10 kHz. To facilitate easy connection

a BNC to 4 mm adaptor is included.
