eL-320 User’s Guide Congratulations on the purchase of the AccuTools™ eL-320 Combustible Gas Leak Detector, the most technologically advanced of its kind. The eL-320’s low power requirements, small size and high sensitivity combine to create a tool which is easy to handle and ultra effective at locating even the most difficult-to-find leaks. The eL-320’s long life sensor will detect concentrations of combustible gases as low as 5 ppm. It is sensitive to all combustible gases.
eL-320 User’s Guide INSTRUCTIONS 1. Move the eL-320 to a fresh-air environment. Press the button to turn the unit on. 2. The LED will flash rapidly for a period of time (see WARMUP TIME, below) to indicate warm-up and auto-calibration, afterwards the unit will begin beeping and flashing green. 3. Unit turns on in the high sensitivity level, which is preferred for most small leaks. To operate the unit in the low sensitivity level, press the button twice (double-click like a computer mouse).
eL-320 User’s Guide WARM-UP TIME The warm-up time for the eL-320 will range between 25 seconds and 1.5 minutes. Each sensor has different warm-up characteristics that change with use over the life of the sensor. The eL-320 has built-in intelligence that recognizes sensor differences and adjusts the warm-up time automatically for maximum sensitivity and stability. MISSING/DAMAGED SENSOR ALARM If the sensor is damaged, a sweeping alarm and a red-green flash will indicate the problem.
eL-320 User’s Guide RECALIBRATION When the eL-320 is turned on, the unit automatically calibrates the sensor for maximum sensitivity. Occasionally, the signal from the sensor may drift (especially if moving from one location to another where the ambient humidity changes), causing a continuous alarm that will not clear. In this case, simply power the unit off and on again, or use the following recalibration procedure: To recalibrate the unit: 1. Move the unit away from any suspected leaks and into fresh air.
eL-320 User’s Guide SENSOR A eL-320 sensor should last many hundreds of hours of continuous operation. A failed or failing sensor will be indicated by a continuous “siren” sound. In addition, it is recommended that the sensor be replaced yearly for optimum performance. SENSOR REPLACEMENT In either case, occasional replacement of the sensor is necessary: 1. Turn the power off. 2. Remove the sensor cap by pulling it from the end of the probe. 3. Pull the old sensor from the socket. 4. Install the new sensor.
