(10)Enter -10 deg using DATA keys.

(11)Press frequency counter RESET pushbutton and record frequency counter

indication.

(12)Determine the difference between indication recorded in (6) above and indication recorded in (11) above. The difference will be between 272.22 and 283.34 ns.

(13)Enter -100 deg using DATA keys.

(14)Press frequency counter RESET pushbutton and record frequency counter

indication.

(15)Determine the difference between indication recorded in (6) above and indication recorded in (14) above. The difference will be between 2722.22 and 2783.34 ns.

b.Adjustments. No adjustments can be made.
