multimeter with scope calibration function

[Jerry Jensen]

I've got a Sears 982015 digital multimeter with a square wave
generator function on it. I want to use the function to calibrate an
oscilloscope but I don't know the frequency nor amplitude of the
signal it produces. Does anyone out there have the manual or other
data on this meter? HElp please. Thanks.

You must not care about the accuracy of your 'scope.

If you need to calibrate it, do it right and invest in the proper
hardware to do a decent calibration. Failing that, professional cal for
older 'scopes is not terribly expensive. As one example, I've been
quoted about $73 for the Tektronix 7904 mainframe.

Happy tweaking.
