A potential drawback of this technique is that sequential sensors (i.e., those
input to the same SET) will not have sequential input locations.

#5 Measure — Enter the instruction needed to measure the sensor(s) (see
Section 6, Sensor Hookup and Measurement Examples). The input location
parameter of a measurement instruction is indexed if a (--) appears to the right
of the input location. Index an input location by pressing “C” after ke
location or by pressing F4 in Edlog while cursor is on the input locati
parameter. Indexing causes the input location to be incremented by 1 with
each pass through the loop. This allows the measurement value to be stored in
sequential input locations. Instruction Step Loop Index (P90), as explained
above, allows the indexed input location to be incremented in integer steps
greater than 1.

If more than the datalogger’s default number of input locations
are required, then additional input locations must be assigned
using the datalogger *A mode. Consult your datalogger manual
for details.
