According to the operator's manual, which is available for download 
on the Fluke web site (see "75/77" for the original 77):

http://us.fluke.com/usen/support/manuals/default.htm?prodcategory=OBS

the rated frequency range for AC voltage and current measurements is 
45-1000 Hz except that for the lowest voltage range it is 45-500 Hz.

Best regards,

Don
