    Ov-1 cr510 datalogger overview the cr510 is a fully programmable datalogger/controller with non-volatile memory and a battery backed clock in a small, rugged module. The combination of reliability, versatility, and telecommunications support make it a favorite choice for networks and single logger a...

    Cr510 overview ov-5 ov2.2 program tables, execution interval and output intervals the cr510 must be programmed before it will make any measurements. A program consists of a group of instructions entered into a program table. The program table is given an execution interval which determines how frequ...

    Cr510 overview ov-6 each instruction in the table requires a finite time to execute. If the execution interval is less than the time required to process the table, an execution interval overrun occurs; the cr510 finishes processing the table and waits for the next execution interval before initiatin...

    Cr510 overview ov-7 input/output instructions specify the conversion of a sensor signal to a data value and store it in input storage. Programmable entries specify: (1) the measurement type (2) the number of channels to measure (3) the input voltage range (4) the input storage location (5) the senso...
