This might have been covered before but here goes anyways, Cal and Cal, first one...Cal 0.2 volts, you've already found that function on the scope, the bit you hang the probe on for probe cal (calibration) the other is also Cal but is shown as C on your scope, there are three of them, one on each of the Y amplitude controls and one on the horizontal time base control, all three being the variable controls not the selector switches.
Taking the Y amplitude cal first, there's two of them one for each channel, channel 1, turn the control anti clockwise so the white pointer is in line with the C shown on the V/cm scale, channel 2, do the same. That now means that the V/cm switch settings are calibrated to the vertical divisions on the screen, eg: if the V/cm switch is set to 2 volts and the amplitude of the waveform on the screen occupies one complete division then 2 volts peak to peak is what you have if a X1 probe is being used.
The same setting procedure applies to the horizontal time base, turn the control anticlockwise so the white pointer points to the C on the ms/cm scale. That now means that the ms&us/cm switch settings are calibrated to the horizontal divisions on the screen, eg: if the ms&us/cm switch is set to 5ms/cm and the time period of the waveform on the screen occupies one complete horizontal division (X mag. off) then a waveform of 5ms time period is what you have, if you want to know the frequency of that then use f=1/T where f is in Hertz and T is in seconds...eg: 1/0.005 = 200 Hertz.
Hope that helps.

What are you measuring it with?
This post might cross, any errors then guilty as charged.
