1.
The ‘Sampling Setup’ field instructs the DATA LOGGER to log
readings at a specific rate and for a finite number of data points.
The Sampling Time ‘combo box’ located beneath the Sampling
Rate and Sampling Points fields shows the total number of days,
hours, minutes, and seconds the Datalogger will run based on the
Sample Rate and Sample Point settings. Note that a sample rate
of 50ms can only be selected for use in RT (real time) mode.
2.
‘Alarm Setup’ allows the user to set HIGH and LOW measurement
limits.
3.
‘LED Flash Cycle Setup’ allows the user to set the time in seconds
between each flash of the LED. Select “No Light” for maximum
battery life.
4.
The Datalogging record mode can be set to STOR (store readings
to memory) or RT (real time) where readings are displayed in real
time on a PC.
5.
The Datalogger frequency weighting can be set to dBA or dBC.
Note: With ‘A’ weighting selected, the meter responds like the
human ear (boosting and cutting the sound amplitude over the
frequency spectrum). ‘A’ weighting is used for environmental
measurements, OSHA regulatory testing, law enforcement, and
workplace design. Select ‘C’ weighting for flat response
meas
urements (no boost or cut). ‘C’ weighting is suitable for the
sound level analysis of machines, engines, etc. Most OSHA
related testing is performed using 'A' Weighting and SLOW
Response Time settings.
6.
The Datalogger response time can be set to FAST or SLOW.
Note: Select FAST to capture noise peaks and noises that occur
very quickly. In FAST mode, the meter responds in 125ms. Select
the SLOW Mode (meter responds in 1 second) to monitor a sound
source that has a reasonably consistent noise level or to average
