For the record, the 30M doesn't need any kind of special setup, apart from a recommended warm-up period of 5 minutes, before accurate measurements are made. If the voltage source being measured is noisy, several filter strengths are available internally, to help steady the readings.
Although I wouldn't use such a specialized meter for continuity testing, it is fast enough, once the resolution has been reduced to the minimum, through the set-up menu.
The meter is also capable of 4-wire resistance and temperature measurements.
There are 2 baud rates available: 9600 and 19200.
