The smart answer to precise resistance & voltage measurement
Initially designed to measure copper winding resistance to within fractions of an ohm and the surface temperature using an infrared sensor. When coupled with the Tiger 320 Series operating system this module, and its on-board current and voltage excitation outputs, satisfy OEMs wishing to accurately measure a range of resistance and voltage/current signals.

The meter has three smart setup registers to configure all smar t input modules.
ISD9 requires smart registers 1 and 2 to be configured. Because this is a dual input module, measuring voltage and resistance, independent sensor inputs can be software selected for Tiger 320 Series meter channels 1, 2, 3, and 4. This module produces two output registers. One of these registers can be transferred to Channel 1 via Code 2, the same or another register to Channel 2 via Code 4, the same or another regi ster to Channel 3 via Code 5, and the same or another register to Channel 4 via Code 6.

The following programming procedures cover all the steps required to configure smar t input module ISD9. Steps 1 to 5 describe how to select the line frequency rejection, the voltage range, and the averaged output rate through smart setup register 1.
Steps 6 to 9 describe how to select the resistance r ange through smart setup register 2.
Steps 10 to 19 describe how to select the output register for channels 1, 2, 3, or 4 as required.
