ECGOLDDUALUM12.doc Model: EC-GOLD Dual 4.0 CALIBRATION 4.1 Calibration Notes Rev: 1.2 The instrument was calibrated and tested prior to leaving the factory. Therefore, it is possible to use the instrument directly out of the box. Under normal conditions, recalibration is recommended once every 6 months. For a two point calibration, the first point is typically Zero (clear air); the second point (also called span) is a determined gas concentration value.
ECGOLDDUALUM12.doc Model: EC-GOLD Dual Rev: 1.2 3. Zero Calibration only needs to be done when installing a new sensor. Press

Model: EC-GOLD Dual ECGOLDDUALUM12.doc Rev: 1.2 4.3 Calibration Procedures (Standard Feature Mode Without LCD / KEYPAD) 4.3.1 CALIBRATION NOTES The EC-Gold Dual may be calibrated using a Single Point calibration procedure, by using calibration push button. The Calibration pushbutton may be accessed using a screwdriver or other fine tool – See Figure 4.1 for the location of the access hole.
Model: EC-GOLD Dual ECGOLDDUALUM12.doc Rev: 1.2 2. The gas sensor is mounted directly behind the Calibration Port in the middle of the front plate of the EC-Gold Dual housing [See Fig. 4.1]. Insert the Quick Disconnect tube into the EC-Gold’s Dual Calibration Port. 3. Start gassing the sensor by opening the valve on the canister. The flow rate is preset to 0.5 Lpm (or ~1 SCFH (Standard Cubic Foot per Hour). Wait about 90 seconds. 4.
Model: EC-GOLD Dual 6.0 ECGOLDDUALUM12.doc Rev: 1.2 TROUBLESHOOTING ERROR DESCRIPTION WHAT TO DO 1. No Output and all lights off 2. 4-20mA output does not track the gas concentration. 3. In Discrete Voltage Output mode, the ISA-66RLU or Gas Alert connected to the EC-Gold always shows Sensor Fault 20 Check the power to the unit. The voltage should be 24VAC/DC at the power connector with the positive and negative connected as shown on the connector label.

MAINTENANCE AND CALIBRATION Your ARJAY / ENMET gas detector is the state of the art in gas detection, but like any other part of your ventilation system, it requires periodic maintenance and calibration. There are various sensor technologies that may be used in your Arjay gas monitor; including solid state MOS, Electrochemical, Infrared and Pellister Pair (Hot wire). These have a normal operating life of 3 to 5 years under ambient conditions.
