Measurement
Data 3 for each sensor
reading Measurement data collected: This data contains only those
measurements set up to be included in the transmission (see Tx
Data Content). The data values are 3-byte binary encoded signed
numbers allowing a range of -131072 to +131071. The actual 6-
bit binary encoded format is described later. The value
transmitted will be value * 10^RightDigits. The string /// will be
sent if the data was never measured or was erased.
All the required values for one sensor (most recent first) before
proceeding to the next measurement. This format is similar to
that used by the Sutron Satlink but different from the 8210.
There will be 3 bytes of encoded data for every sensor reading.
The number of readings depends on the user setup.
Additional
Measurements Variable If more than one measurement was set up for transmission,
more data will follow. Each measurement setup will have data
starting with the Measurement Delimiter and ending with
Measurement Data.
Battery voltage 1 This is the battery voltage measured prior to making the
transmission. The range of the number will be -32 to +31 and can
be converted to volts by multiplying by 0.234 and adding 10.6
allowing a range of 3.1 to 18.1 volts.
