7.1 Storage types
As well as manually storing individual values (see
“Storing
a measured value”
on page 47), you can also store entire
sequences of measurements automatically.
There are two ways to do this:
• You can start storing results at a specified time and stop
storing them again after a defined time period has
elapsed (see
“Recording measurements by timer
control”
on page 80).
• You can set the instrument to start storing results
depending upon the measured field strength (see
“Recording conditional measurements (optional)”
on page 82).
7.2 Recording measurements by timer control
For timer controlled recordings, measured values are
recorded without interruption within the specified time
period and are combined in 3 values per measurement
interval (minimum value, maximum value, and average of
the measurement interval).
The averages can be very easily converted subsequently to
other averaging times with the NBM-TS PC Software (post-
average function).
You must take the following steps to record measurements
by timer control:
1. Set the recording parameters:
– enter the starting time (Timer Start),
– enter the recording time (Timer Duration),
– enter the recording interval (Timer Interval).
2. Select
Timer Logging
function to start the recording.
These steps are explained below.
