FAQs

How do I check the calibration and then recalibrate the ECRN-50 or ECRN-100 tipping bucket rain gauge?
The tipping bucket rain gauges have small stops that can be adjusted such that the bucket tips after the appropriate volume of water was collected in the bucket. Calibrate ECRN-50 when wet because a little water remains in the cup. Volume-per-tip values can be found in the rain gauge quick start guides below:

ECRN-50
ECRN-100
What is the maximum flow rate for the ECRN-100?
12 mm/minute
What is the volume per tip for the ECRN-100?
ECRN-100 volume per tip: 4.02 ml/tip

Rainfall per tip: 0.2 mm/tip
How do I assemble the anemometer mast?
The anemometer mast is suitable to mount METER’s above-ground sensors: ATMOS 41, ATMOS 22, ATMOS 14, PAR, PYR, IRT, SRS, PHYTOS 31, ECRN-100, ECRN-50, and ECT. For assembly, read: "Anemometer Mast Assembly Instructions."
