Zero Cal-Check performs a companion test to the calibration validation feature offered on the company’s Model FT3 thermal mass flow meter and temperatureFox Thermal transmitter. While the calibration feature tests the functionality of the sensor and its associated signal processing circuitry, Zero Cal-Check checks for buildup on sensor that could affect calibration; validates the zero stability of the meter; and checks thermal conductivity (heat transfer) repeatability of the sensor.
