VIBRATRON II
Vibration Sensitivity Tester
1.0 GENERAL DESCRIPTION
The Vibratron II provides a means of measuring sensitivity to vibration in the hands and feet.
The instrument consists of two modules with vibrating posts and a controller. Vibration amplitude is
measured in microns (1 micron = 10
-4 cm) and either post can be set to vibrate at different amplitude lev-
els. (The digital display reads in vibration units which bear a square law relationship to the peak to peak
amplitude in microns.) During testing, the subject is asked to detect, with finger or toe, which of the
posts is vibrating. There are two vibration ranges.
2.0 INITIAL INSTALLATION
2.1 EQUIPMENT SUPPLIED
After unpacking the instrument, check that all parts of the system are present. The box should contain:
1 Controller, with AC line cord
1 Vibrator Module A
1 Vibrator Module B
2 Vibration Damper Mats
1 Carrying Case
1 Operating Manual
2.2 CONNECTING VIBRATOR MODULES TO THE CONTROLLER
Insert polarized electrical connector from each vibrator module to the matching socket on the back of
the controller.
Be sure module A is connected to socket A, and module B to socket B. Twist locking nuts in a clockwise
direction to lock connector to controller.
Place vibrator modules on damper mats.
2.3 SETTING LINE VOLTAGE SELECTOR SWITCH
This instrument may be used on 110V AC or 220V AC by a simple adjustment on the rear of the control
box. Voltage selector will normally be set at the factory for 110V. If you are using 220V AC line, check
and set unit as follows:
a) Disconnect controller from the AC line
b) Using a 1/4” flat screwdriver blade, pry out the
fuse holder in the AC input socket on the rear panel.
(See diagram at right.) For 220 - 240V AC operation
insert the fuseholder so that the arrow indicating
220V operation aligns with the arrow at the bottom
of the input module.
