One of the most important functions of the Service Logger is to record
information over a period of time. This function is like a chart recorder except
that the information is stored in memory rather than being printed on paper.
The user can choose to print the information, transfer the information to a
computer for advanced analysis or long term storage, or review the information
on the Service Logger’s display.
In the case of the OM-60-MOD-TE sensor, the temperature and presence or
absence of voltage will be recorded. Different sensors will, of course, record
different information depending on the function of that sensor. The Service
Logger has a memory capacity to record up to 4000 samples of data. It is the
option of the user to record data to the maximum capacity of the Service Logger
or to terminate a recording when sufficient information has been gathered.
IMPORTANT !
Each new recording will erase any previously recorded information. It is the
responsibility of the user to either print or store a previous recording prior
to starting a new recording.
The first step in making a recording is to select the proper recording time and
sample rate. If a sampling rate of 15 seconds is being used, then every 15
seconds the temperature and presence or absence of voltage will be measured
and stored into digital memory. No record of information is made between each
sample even though the display will continuously show the environment the
OM-60-MOD-TE sensors are exposed to.
If the Service Logger is set to record on event change, then only when the state
of the voltage detector goes from ON to OFF or from OFF to ON will a data
recording be stored in memory.
For a recording to accurately reflect a series of events, it is up to the user to
select a recording interval that best suits the particular application. In some
situations maximum recording time may be sacrificed so that more frequent
sampling may be accomplished. Long term monitoring will require less frequent
sampling in favor of longer recording times. The record on event change will
usually be used when the data of interest occurs only under a specific
condition.
The next step is to select how the Service Logger will record the information
from the OM-60-MOD-TE sensor. There are 3 possible ways to record
information.
