Goupchn High Voltage Oscilloscope Probe P4100 with Accessory Kit 100MHz 2000V 100:1

fried on first use. total junk

This is a 100X probe not a scope nor does it have a 10X switch. It does what it is intended for. Some people dont read. It can be used to measure up to 2,000 Volts DC and 2,000 Volts P-P AC not RMS. If your confused by the numbers or letters used above dont buy it nor use one. 2,000 Volts will kill you and hurt while it is burning thru you. RMS voltage times 2.8284 will give you Peak to Peak Voltage. 2,000VAC (RMS) is equal to 5,656.8 Volts Peak to Peak. So the limit for AC is 707.11 Volts RMS on this probe. And people hands off when measuring 2KV. It is a good probe and functions correctly and I like it!

Nice quality at a fantastic price. Works well and as expected. Great value!

I do some work on old vacuum tube ham radios. It is fairly common that the final amplifier tubes have 600-800 volts DC on them. Then the signal of 100+ volts AC is applied on top of that. Most 10x probes that come with an oscilloscope are good for 400-600 volts before you destroy them. So, these 100X probes that are good to 2KV are an important tool. I have used this one I purchased only once. But, it works as intended and meets my needs. The probe appears to be well built, reliable and safe to use

I was not using this for the spaceship I am building in my kitchen, but instead for looking at alternating current waveforms from backup power devices to see if they are cool for my electronics. The spaceship will wait.

This 100:1 scope probe is well made, and worked perfectly allowing me to scope signals that would damage the inputs on my scope. For instance, I wanted to visualize the 60 Hz AC sine wave that was present on a standard 120 VAC line. Because of RMS voltage, the actual line voltage would have been much higher than the input rating on my scope, thus being dangerous and damaging it. By using this 100:1 attenuation probe it was now possible to safely view the waveform. If you set your scope on 100X setting then even the scales read properly on the display.
