AEGIS® Shaft Voltage Tester™ Digital Oscilloscope


Digital Oscilloscope and Multimeter with Conductive Microfiber Probe Tips

Is your motor safe from destructive shaft voltages? For the first time you can get all of the tools you need to find out in one place. The AEGIS® Shaft Voltage Tester™ Digital Oscilloscope bundle includes the AEGIS-OSC-9100 100 MHz digital osciloscope, shaft voltage probe tips, and a shaft grounding simulator. Armed with these tools, you can quickly and easily find whether your motors are at risk of premature bearing failure due to VFD-produced bearing currents.


Calibrating the AEGIS® Shaft Voltage Tester™

The AEGIS® Shaft Voltage Tester™ comes factory-calibrated. It also has a built-in self-calibration feature (described on page 48 of the user manual). But Electro Static Technology also recommends having the scope professionally recalibrated annually to ensure its accuracy. A partial list of calibration companies who can do this is given below.

For some applications, an oscilloscope must be calibrated to according to the requirements of a standards organization, like ISO 17025 or ANSI Z540. These more rigorous standards add expense and lead time, so we advise users to find out what, if any, certifications are required for equipment used in their facilities, before having the calibration done.

The initial factory calibration of the AEGIS® Shaft Voltage Tester™ does not comply with these higher standards; however, we do offer one Tester™ package that comes ISO 17025 certified, part number AEGIS-OSC-9100MB-W2-IC.
