PROBLEM SOLVING
15.1 Common issues
15.1.1
When the results in LiveView remain "---"
irradiation to expect and by multiplying this by the given sensitivity one has an estimated voltage to be measured.
Indoor all readings will always be very low and sometimes even negative due to warming and cooling as a result of holding the
instrument.
15.1.2
Several intervals, I'm confused
15.1.3
My modem doesn't work
There are many possible reasons for a failure in this inherently difficult area.
1)
Check if the SIM card has working internet capabilities by temporarily putting it in a smartphone and perform internet
browsing or social media updates.
2)
Make sure it has a PIN
3)
The settings given in section 10.8 are a good starting point to have the LOGBOX SE sent e-mail log files using the
Physicus emailbox and server. Once this works you can change to your own server and try again.
4)
Often the GSM signal in the office or building can be to weak or unstable to work properly. Try to put the small antenna
outside for a better signal.
5)
When a TimeServer and TimeZonehave been selected, at midnight the internal clock will be synchronised. Logged
data afterwards could have a different time stamp but a big difference is only to be expected the first time there is a
synchronisation and only when the time and or date weren't set properly.
please check if Measure has been selected in the Analog, Digital or Serial window:and that in
the Output window the correct INPUT is chosen, with optionally Min, Max, SDev and that the
right Poly is selected.
When in doubt about the POLY we suggest to select one with A1=1 and recheck in LiveView.
When there is still not the expected result please check the wiring and if possible use a digital
multimeter to measure the input voltages on AIN1-4 and GND or across AINx + and –
The instruction sheets of our products will give you an indication of the normal amount of
The settings to the left are save settings for diagnosis.
Every
VREF, Pt-100 excitation and POWER are switched on and after a 1 second
wait (MeasDelay) the actual measurement is performed.
Two measurement periods of 2 seconds each fit the selected 4 seconds
LogInterval. These measurements are averaged and used for Min, Max,
SDev.
In LiveView every 4 seconds there will be a line with the selected outputs
