Table 7. Device Configuration Modbus Holding Registers
∆ Warning!! Device threshold configuration variables should be set by the user to values scaled based on the Units configuration
setting. The detector will interpret the value differently for different Units settings. E.g. The device will interpret a 0.01 threshold
setting as 0.01 %/ft when Units setting is US Standard. The device will interpret a 0.01 threshold setting as 0.01 %/m when Units
setting is Metric.
