Page 7: Combustible Gas Detector
This drive current is factory set and is dictated by the combustible gas to which the detector is calibrated. Consult RKI Instruments, Inc. if you plan to change the calibration gas for the transmitter, for example from a methane calibration to a hexane calibration. The amplifier includes the detector terminal strip, controller terminal strip, span pot, zero pot, and test points (see Figure 1). -
