1. Product Description

SC-100 is a battery operat ed, easy to use instrument which is used to check sensor condition by measuring
bias voltage and to electronically simulate IEPE sensor output from accelerometers.

Power is supplied from one internally mounted 9V alkaline battery. There is also a LED indication of LOW
battery.

Operational mode can be selected by side switch mounted on left side. There is also a visual indicator of
selected mode placed on the front panel. In the middle position device is OFF.

In BOV TEST mode, the user can r ead measured bias volt age on the screen, and sensor status indicated on
the LED diodes on the front panel. There are three predefines sensor status’ which are related to the bias
voltage and they are: SHORT CIRCUIT, SENSOR OK and OPEN CIRCUIT.

In SIGNAL GENERATOR mode, the instrument produces a fixed frequency sinusoidal signal to simulate
accelerometer or velocity sensor output.
