Most multi-meters only measure voltages up to 1000 volts. How do you measure voltages often used with tubes like 3-500z or 3cx1500a7 tubes? Will the range extended from Fluke listed below work with a 1000v 10 mega ohm multimeter? 80K-6 High Voltage Probe http://www.fluke.com/fluke/usen/acce....htm?PID=55358 The multimeter I have is the Radio Shack 22-801 which is rated for up to 1000 volts. Radio Shack 22-801 owner's manual http://www.radioshack.com/graphics/u...0801_PM_EN.pdf Thanks Michael DO THIS WITH EXTREME CAUTION. Knowing the input resistance of the meter it is easy to use a series resistance to scale the input voltage. I have inserted 11M in the front end of my 11M input impedance meter to make a 2X voltage divider. I connected the meter to the circuit, placed it in a Pyrex baking dish for insulation, stood at a distance and energize the power supply. I used several HV resistors removed from an old TV because I figured there was a danger of arc over using common resistors. I was truly surprise the meter didnt melt down annd the house main breaker didnt trip. Jimmie |
