TB3 Calibration

• TB3 rain gauge is calibrated at the factory prior to shipment

• TB3 should hold its calibration for 100,000’s of events prior to a calibration being required

• Prior to conducting a calibration check, a thorough cleaning of the rain gauge is required

• most often a cleaning will bring the TB3 back into specified accuracy without having to do a calibration

Specified accuracy is +/- 2% for 0 to 100mm/hr.
