Set New Data Saving System - Adash A3716 User Manual

ADASH Ltd.
min
Values below threshold are saved when time interval elapses only (these values are typically noise
values). Only the first noise value lower than the threshold is saved.
The value differs for each physical unit and is stored in following format (unit, value; ...):
min=µm,5; mm/s,0.5;g,0.3;mV,5;Hz,0.01
abs
The new value is saved if the absolute and relative change (between new and last saved value) is
higher than the set value. The abs param is an absolute part of a significant change. The value is
stored in the same way as min.
abs=µm,10;mm/s,0.1;g,0.1;mV,5;Hz,0.5
rel
The rel param is the relative part of the significant change. The 0.05 value means 5 %.
rel=0.05, 0.1, 0.2, 0.5
In A3716 FW version 027804 and newer only the first value is taken account. In older versions the
adaptive algorithm uses the values in the row.
Examples
To save all data:
all readings=1
All readings will be saved. Beware that this option can fill the hard drive very quickly.
To save data only in defined intervals:
all readings=0
adaptive=0
statics interval save=60
short dynamics interval save=180
long dynamics interval save=3600
'Check changes' algorithm is disabled (adaptive=0). Static readings (measurements) will be saved
every minute, short dynamics every 3 minutes and long dynamics every hour. Intervals are always in
seconds.
Use 'check changes' algorithm
all readings=0
adaptive =1
statics interval save = 21600
short dynamics interval save = 21600
long dynamics interval save=21600
Check changes algorithm is enabled. Static values, short dynamics and long dynamics are saved
every 6 hours until there is no significant change in value.

Set new data saving system

After upgrade to firmware versions 2.79 and higher, you would like to use new data saving system
also for older databases (created in older DDS and firmware versions). This is not done automatically.
Follow these steps to change data saving system for databases created in older versions of firmware
and DDS.:
1. Click on any item in the tree with right mouse button.
2. From menu choose option 'Set New Data Saving System'. Warning messages and question
windows will pop up. Click through them.
