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 keying the location or by pressing F4 in Edlog while cursor is on the input location 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. #6 Optional Processing - Additional processing is sometimes required to convert the reading to the desired units. It may be more efficient if this processing is done outside the measurement loop. A second loop can be used for processing, if necessary. 19
