HP 1740A Oscilloscope Help ... Voltage Amplitude is Exactly 10x too Small

[Pork]

So my HP 1740A is displaying the voltage exactly 10x too small.

If the volts per div is set to .1 and the probe is connected to the 1V Cal, I get a one division reading (same for both A & B).
The amplitude of the reading is exactly 10x smaller than it should be and I can't seem to correct it.


Help

What I know:

Probe is a Tek P6122 (10x)

1V Cal has been set to .500 volts with a Fluke 177 DMM

Depressing the blue 10x button on the scope increases the width of the signal.

Depressing the tan 5x button increases the amplitude by 5x.

Please don't double post or the moderators will get right up you.

Please don't double post or we (moderators) have all the users getting "right up us" about it. There is nothing more annoying for anyone to take the time to reply to a post only to find there is another one with more discussion on it than the one you posted on and what you took the time to write had already been written.
