4.0 MISCELANEOUS SETUP
Each remote EC Gold transmitter may be individually setup and calibrated via the CAP unit. Setup from
the CAP is more convenient than using the EC Gold integral switches. Calibration, on the other hand, is
usually best done at each EC Gold since the sensor has to be gassed. A handheld calibrator may be
purchased for easy calibration.
NOTE: The CAP acts as a user interface to the remote EC Gold transmitter being
calibrated. The resulting setup and calibration values reside in EC Gold transmitter and
not in the CAP.
4.1 CALIBRATION
The EC Gold transmitter is pre-calibrated at the factory, but field verification with a known
concentration of test gas should be performed to ensure proper operation of the system. Field
calibrations should be scheduled every 3 or 4 months as part of a regular maintenance program.
The EC Gold transmitters may be calibrated either using the CAP or at the EC Gold itself using the
convenient single point pushbutton procedure. The latter method is quickest since calibration involves
exposing the sensor of the EC Gold transmitter with a calibration gas i.e. the procedure requires
someone to fit the calibration cup over the EC Gold’s sensor housing.
Calibration via the CAP is practical if there are 2 people equipped with 2 way radios calibrating the EC
Gold transmitters (one at the CAP and the other gassing the sensors).
4.2 CALIBRATION USING EC GOLD PUSHBUTTON
To calibrate the EC Gold transmitters using their integral calibration pushbutton, refer to the EC Gold
manual for the latest calibration procedure information.
4.3 CALIBRATION FROM THE CAP
The following procedure describes how to individually calibrate any remote EC Gold transmitter from the
CAP unit. As mentioned earlier, this method is most convenient if performed by 2 people communicating
via radio transceivers. This method is also preferred if the calibration gas can be selectively applied to
the EC Gold transmitters via tubing from a centrally located calibration gas canister. In this scenario, one
person can conveniently perform calibration.
The following procedure is for calibrating from the CAP panel and applies to either of the 2 methods (2
people or a single person with control over calibration gas to remote transmitters).
1. If not at the main Remote Setup Menu, press the CAL key, then enter the password at the prompt.
The factory set password is 2000.
2. Press 1 for Calibration from the Calibration menu
3. Select the Address of the desired EC Gold transmitter to be calibrated.
4. The calibration menu offers 3 types of calibration: auto cal, manual cal and direct entry of the slope
and offset.
4.3.1 AUTOCALIBRATION
Autocal is the most common form of calibration. In this procedure, the gas sensor is
exposed to 2 different gas concentrations in turn – one of which can be clean air (0
ppm CO). The concentration value is entered for each. The EC Gold is then
instructed to calculate the required calibration parameters.
1. Press the CAL key to enter the EC Gold Setup menu.
2. Press 1 for Sensor CAL.
