*: Reference value. With the Average function, the measuring time is
determined by multiplying the measuring time by the number of averaged
measurements.
This varies with the function range. Use the sampling period (free run) in
Chapter 10 Specification as a guide.
When set to FAST, the unit performs a self-calibration every 30 minutes
for a duration of approximately 55 ms each time.
