The AEGIS® CAT II/III Shaft Voltage Tester™ digital oscilloscope from Electro Static Technology (Mechanic Falls, ME) enables testing of industrial motors controlled by variable frequency drives (VFDs). The tester is designed and configured to take and capture voltage measurements from the spinning shafts of motors. The digital oscilloscope comes with a conductive microfiber-tipped probe, a probe holder with magnetic base, and a carrying case. The 2-channel, full-function, 100-MHz oscilloscope has a 5.7" TFT LCD color display, a multi-language user interface, and a 5-hour rechargeable/replaceable lithium-ion battery pack. The oscilloscope is capable of sampling rates of 1 GSa/s to 50 GSa/s, and has a USB port for data transfer or flash drive storage.

With dual inputs, the tester combines oscilloscope, multimeter, and recorder functions in a single unit. The multimeter function provides measurements for resistance (ohms), continuity, diode capacitance, DC volts, AC volts, DC current, and AC current, all at 6,000 count display resolution. Accessories include a 9V/4A power adapter, 1X/10X oscilloscope probes, test leads for the multimeter, a probe calibration tool, a rechargeable/replaceable 5-hour battery, and a USB flash drive.
