ESM-30 only: Data recorder

Save interval:

The time between consecutive saves of 
recorded data can be set between 1 second 
and 3 minutes using the ESM-TS Interface 
Set.

Data set:

The r.m.s., maximum and minimum values are 
calculated continuously during the selected 
save interval (the interval between 
measurements is 5 ms, all data are referred to 
the relevant permitted power flux density in 
the same way as the displayed value). 
The data for the E-field and H-field are saved 
in the data recorder as a data set with a 
timestamp at the end of each save interval.

Data block:

All data sets recorded between switching on 
and switching off the ESM-30 “RadMan XT” 
are combined into a data block. Several data 
blocks can be stored in the data recorder at 
any one time. These data blocks are accessed 
by the ESM-TS Interface Set for evaluation.

Accessing the data using ESM-TS may result 
in a brief interruption in the data recording. If 
this happens, the current data block will be 
closed and a new data block started after the 
interruption.
