3. At the prompt, enter the address number of the desired EC Gold transmitter to be calibrated.

4. From the Calibration menu press 1 for Autocal.

5. Gas the EC Gold sensor being calibrated with the first gas. Ambient air can be used as 0

ppm ONLY if it is certain that there is no CO in the air. Enter the concentration of the first gas

in ppm for this first point. The bottom line displays the raw sensor reading in mV and is

displayed to give an indication when the reading has settled. This typically takes about 1

minute. Press Enter to confirm the first calibration point.

6. This display now prompts for the second calibration point. Remove the first calibration gas

and let the sensor settle in air until the reading returns to clean air levels.

7. Repeat step 5 with the second gas concentration.

8. In case of calibration errors such as low sensor sensitivity, or user entry errors, an error

message is flashed for about 2 seconds after the ENTER key has been pressed.

4.3.2 OTHER CALIBRATION METHODS

There are 2 other methods. Both require a prior successful autocal. The first

method allows manual entry of 4 points: the concentration and raw sensor values for

each of 2 cal points. The EC Gold is then instructed to calculate the required

calibration parameters.

The final cal method is to directly enter the calibration values i.e. the SLOPE

sensitivity) and the OFFSET (or raw value in 0 ppm CO).

4.4 VIEWING EC GOLD TRANSMITTER INFORMATION

1. Press the SETUP key then 2 for Xmtr Information.

2. Press 1 for the Sensor Values / Stat menu, then at the prompt, enter the address of the desired

EC Gold transmitter.

3. The CO concentration in ppm, the sensor signal in mV and Status for the selected EC Gold

transmitter is displayed.

4.5 VIEWING EC GOLD REVISION/ SERIAL NUMBER INFORMATION

1. Press the SETUP key then 2 for Xmtr Information.

2. Press 2 for the Revisions /ID, then at the prompt, enter the address of the desired EC Gold

transmitter.

3. The Software rev., Hardware rev., and serial number of the selected EC Gold are displayed.

4.6 mA OUTPUT (from terminal 7, 8)

1. mA output may be ordered in place of enclosure mounted buzzer. Ma output is based on the

highest ppm and the span is set in the control setting. See 3.6.6 for setting mA Span.

2. mA outputs are also available by ordering mA Output Boards or from Auxillary Boards.

No mention of How to set up mA outputs as well as select CH1 output instead of buzzer. No mention

of viewing mA output with key # 9.
