Testing lambda on-off ratio

Which function does this correspond to on a multimeter please? Also, the manual states to connect the on-off ratio tester to the diagnostic socket and press the 100% button. Again, which button would this correspond to on my digital multimeter. My DMM has a duty cycle function.
