To consult them, apply the same procedure as described in the section 10.6.4 on viewing
data while measurement is in progress.
10.6.7 Overload indicator
The SC310 is equipped with an overload indicator for each function. If overloading occurs
during measurement, the
^ sign will appear before the function affected by overloading.
When a function registers overload, its corresponding measurement will be incorrect.
When overloading occurs, the indication will appear in the bottom right-hand corner of the
screen.
10.7 Data registering
The
SC310
can record in the internal memory the values at the measured functions. When
turning on the equipment, the recorded data will not be lost and can be retrieved and
displayed directly from the
SC310 or transmitted to a PC. The memory can be erased directly
from the SC310 .
Two kinds of registers may be saved in the memory:
• The final results of a measurement.
• Continuous recordings of functions with programmable recording time.
10.7.1 Saving final results
Once you have completed a measurement ( ), the results may be stored in the memory by
selecting the SAVE RESULTS option from the main menu. The SC310 will indicate the
register number in which to record the data.
The SC310 stores the following information:
• Vibration mode:
o
Average acceleration (RMS) with evaluation time T for one-third octave band
centred in the frequencies 1, 1.25, 1.6, 2, 2.5, 3.15, 4, 5, 6.3, 8, 10, 12.5, 16,
20, 25, 31.5, 40, 50, 63 and 80 Hz (without frequency weighting) expressed in
m/s
2
and as an acceleration level in dB referred to 10
-6
m/s
2
.
o
Average acceleration (RMS) with frequency weighting W
m
and evaluation time
T; expressed in m/s
2
and as an acceleration level in dB referred to 10
-6
m/s
2
.
o
Peak acceleration (PEAK) with frequency weighting W
m
and evaluation time T;
expressed in m/s
2
and as an acceleration level in dB referred to 10
-6
m/s
2
.
o
Crest factor (CF). Expressed in linear and logarithmic (in dB) format.
o
MTVV: Maximum Transient Vibration Value. With frequency weighting W
m
and
evaluation time T. Expressed in m/s
2
and as an acceleration level in dB
referred to 10
-6
m/s
2
.
o
VDV: Vibration Dose Value. With frequency weighting W
m
and evaluation time
T. Expressed in m/s
1,75
.
o
Multiplying factor K according the old ISO 2631-2:1989
o
Evaluation time T
o
The date and time of the beginning of measurement.
The SC310 may store a total of 1000 final results.
