Q. Can the BetaGauge 330 be field recalibrated?
A. Yes. The BetaGauge 330 is calibrated through the serial port like many Martel calibrators. Other than a computer with a terminal emulation program (we normally recommend HyperTerminal), a LEM232 serial communications cable is needed along with a URA-1 RTD adapter. Both of these can be purchased through your Martel distributor.
You will also need some adequate standards for pressure, current (mA), voltage and resistance.
The procedure is available from the factory or your local Martel distributor.
