Mode 2

• 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.

Mode 3

• 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.
