MeasurementTime
which the sample is taken in
(page 60). This parameter must be greater than 17 and
less than 1,179,630.
When measuring a periodic source such as a monitor,
sample at an integer number of periods. Setting the proper
integration time for a monitor at a specific frequency is
essential to obtaining accurate, repeatable measurements.
Each value set in
microsecond. Use this equation to find the integration time:
Multiply the integration time by the number of cycles
you want to measure (31 cycles are recommended). For
example, with a 75 Hz monitor, use this calculation:
Thus, the integration time is:
413,333 microseconds = .413 seconds
