3.16 Remote Gas Calibrator
The S4000CH has optional accessories called the Remote Gas Calibrator (RGC) and the
High Temperature RGC (RGC-HT). They are designed for remote or difficult to access
locations. They cover the sensor and allow a controlled flow of gas to it. This allows
calibration in high wind conditions and can be permanently attached to the sensor. Since it is
permanently attached, it is useful for remote locations. The calibrators use a constant
pressure. For calibration using the RGC or the High Temperature RGC, refer to Section
3.14.1.

3.17 ARGC Gas Control
The S4000CH has a Modbus or HART controlled output that can be used to turn the cal gas
on and off remotely if the proper plumbing is provided.
