If it is not in Auto mode, verify that it was set to HCalib mode. A common
error is to leave it in Manual mode.
Reset to HCalib mode and let the sensor establish baseline at
midnight. Re-check the sensor operation the next morning after 6 am.
•
If in Auto mode, execute the [.fl] command.
Ex: ?<Enter>
.fl<Enter>

20.
Power input voltage at the CS725 (after protection diode drop)
Verify that there are K counts total (column 4) and that there are about 6 times the counts you
measured the day before when evaluating the site, as the ouput is over a 6 h period instead of a
1 h period.
Verify that there are Tl counts total (column 6) and that there are about 6 times the counts you
measured the day before when evaluating the site, as the ouput is over a 6 h period instead of a
1 h period.
SWE at (7) should be ‘0’
SWE at (9) should be ‘0’
