For example, if the value of channel 1 is 5300, the date is 02/12/2016 and the time is 13:51:00, then
message would be:
002716
cal0=’5300 02/12/2016 13:51:00’
For example
: consider the following scenario:
A technician has finished installing a hydroSpider which is connected to an electricity meter. The
pulse rate has been correctly calibrated within the hydroSpider to 10 pulses per kWh, however the
actual reading on the meter does not match what is showing on the hydroSpider.
Attempting to read the meter and update the hydroSpider via the web-browser at that exact
instance may not always be possible (for example: when the meter is far from the hydroSpider). To
solve this, the technician notes down the actual reading from the electricity meter and the date and
time of this reading. In this example, say the reading was 5300kWh and was taken on 02/12/2016 at
13:51:00. The technician sends an SMS to the hydroSpider with that data, asking it to calibrate the
channel:
002716
cal0=’5300 02/12/2016 13:51:00’
When the hydroSpider receives this SMS, it will search through its own log file, calculate the
difference between its own logged data for the channel at the date/time given and the value
provided via SMS, and then apply a correction to future logged data.
