NARDA 8718B - Manual (Page 45)

44 Operating the Meter
• Collect a series of up to 999 spatially-averaged data
points, one at a time, and automatically assign a
reference number to each data point. Both the average
value and the maximum value at each location are
stored. The reference numbers can refer to either site
plan locations or to a diagram of the industrial
equipment being surveyed. Each data point also has a
time and date stamp.
• Automatically collect a series of data points at specific
intervals of time for a specific time period. Each data
point also has a time and date stamp.
Format for Logged Data
A record contains a header and one or more data points. Each
record is identified by a user-defined two-digit survey number
and the time and date the survey was performed. The header
defines the serial number of the 8718B meter, its calibration
date, the probe model used, and a number of other settings.
These settings may include logging rate, frequency correction,
averaging mode, and averaging time.
If the probe used was selected from memory, the header will
also include the serial number of the probe and its calibration
date.
