Module No. 3513

Checking the Change Between Two Barometric Pressure Readings (Barometric Pressure Differential)

In the Barometer/Temperature Mode, the display shows the current measured value, and a graphic indicator of the differential between the automatically measured current value and the latest value measured at two-hour intervals.

Example: Barometric pressure differential of -3 hPa (approximately -0.09 inHg)



The barometric pressure differential graphic indicator will not be displayed if the barometric pressure differential exceeds ±10 hPa, or if the barometric pressure measurement value exceeds the measurement range.
