Hi,
Current measurement using internal shunt resistor may prove difficult to achieve because there is measurement relay which separate output circuit of the sensor with shunt resistor. Using a default measurement delay of 10 ms may not be enough for some sensor.
Thus the only solution is increasing measurement delay, however some sensor may need a couple second to establish stable current output and if we combine the process with statistic (statistical schedule) thing may not go as we planned. On the top of that the data time stamp will get delayed as well.
There is method to lock the timestamp according to measurement. We can use CRON trigger on statistical schedule but we must do the text programming.
Example:
BEGIN
RS[7,17,27,37,47,57:*:*]
RA1M LOGONA
1#I(MD2000,"UV_Current_AVG~mA",FF6)
1V("UV_VOLT_dummy~mV",A,AV,FF6)
2PT385("PT_Ext_temp~degC",4W,100,FF4)
REFT("INT_TEMP")
END
Best regards,
