TPI 460 Hand Held Oscilloscope features 20 MHz Bandwidth Capture signals from AC/DC drive motors, sensors, actuators, line and control voltages, UPS and industrial machines. Cursor Readout-Measure the width and amplitude of the signaland display it on the screen instead of trying to figure it out manually. Trend Mode Graph readings over a predetermined time period to check for surges or dropouts. Dual Input View two waveforms on the display for comparison and troubleshooting. True RMS DMM Measure AC/DC volts up to 600V, frequency to 20 MHz, and resistance to 20 Meg ohm. Obtain accurate measurements of non-sinusoidal AC voltage and current waveforms found in controls and circuits with True RMS. Real Time Sample Rate Capture spikes and dropouts of industrial signals with real time sampling of 25 megasamples per second. Bright LCD Backlight Adjust brightness levels for clarity in any light condition. Optically Isolated RS232 Output Transfer data safely without a direct connection to your computer's circuitry.
