Tek 2236 Scope: Counter/Timer/Multimeter (CTM) Problem
I've got a problem with the Counter/Timer/Multimeter (CTM) function
of a Tektronix 2236 oscilloscope. The CTM is not operating correctly when I try to measure the voltage on channel 1. When I try to measure the DC voltage of channel 1 (DC Coupling), the fluorescent display reads "DC OUCH" indicating an overvoltage EVEN when NO voltage is being applied. When I try to measure the AC voltage of channel 1 (AC Coupling) the fluorescent display reads "AC 0.0013" (or somewhere around there) regardless of what voltage is applied to channel 1. The CTM measures voltage correctly when I use the multimeter connector inputs on the right side of the oscilloscope. Therefore, it appears that CTM is basically functioning, but there is some sort of problem in the coupling of the channel 1 signal into the CTM. Anybody familiar with this problem? Thanks, Michael |
