1. Product Description SC-100 is a battery operated, 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.
There is also a LCD screen which displays measured bias voltage in volts, when the device operate in BOV TEST mode. Figure 2. Empty battery notification 6 of 11 SPECTRUM Instruments Ltd. P:1-800-778-3428 F:1-866-782-0106 E: info@spectrum-instruments.com...
