1. The sensor detects changes in concentration not absolute con centration making it easy to detect leaks even in areas with refrigerant in the air The SRL2 detects leaks as small as 0 1 oz year which exceeds the toughest SAE J1627 standards The SRL2 comes with wall and car charger for its ultra compact Lithium ion battery which powers the SRL2 for 8hrs of continuous operation before a recharge is needed That s long enough to last your entire workday Unlike many leak detectors oil vapor does not trigger the SRL2 The SRL2 has vari able sensitivity set tings keeping nui sance tripping to a minimum A quick and automatic 30 second self calibration upon power up ensures optimal performance A built in replaceable filter blocks moisture and harmful particulates The SRL2 also has a mute button and a peak hold func tion Turning the PEAK function off will clear the peak change The PEAK LED will light wnen PEAK func tion is on Turbo Mode The TURBO function is an additional 4th sensitiv ity that pushes the SRL2 to it highest possible sen sitivity This feature is activated by pressing the PEAK button four times in succession and can only be activated while on the high H sensitivity level When in the TURBO mode the first green LED on SRL2 will strobe and the audio detection sound will be a solid tone To exit the TURBO mode press the PEAK button again four times in succession or switch from high H to one of2. to 140 F 60 C less than 1 month 4 F 20 C to 113 F 45 C less than 3 months 4 F 20 C to 68 F 20 C less than 1 year Charging Two chargers are included with the SRL2 The AC charger plugs into a wall outlet and the car charger plugs into a car cigarette lighter DC plug 1 The battery is partially charged when packaged Fully charge the battery before first use 2 The LOW BATT LED will light red when the bat tery is low Charge can be checked at any time the unit is on with the Battery Check function See Operation section 3 To recharge the SRL2 plug one end of the charger into the top of the SRL2 and the other into the power source LOW BATT will blink while charging until the battery is fully charged When the SRL2 battery is fully charged LOW BATT turns off 4 Charge within operating environment specified in the Specifications section in this manual 5 Avoid frequent full discharges Several partial discharges with frequent recharges are better for lithium ion batteries Unlike nickel based bat teries they have no charge memory and do not need to be discharged before charging Storage The battery should have a 40 50 charge dur ing prolonged storage of a month or longer See Specifications section in this manual for proper stor age environment Battery life is dramatically reduced if the battery is stored fully charged and or at high temperatures Patents 6 791 088 and 7 022 993 Not

5. ges in cross section or direction of these lines The SRL2 detects changes in concentration of refrigerant not the absolute concentration of refrig erant This lets the user easily detect leaks in places that may have refrigerant in the air such as a refrig erator leaking into an enclosed space Because the SRL2 detects change there is a specific double pass method used to find leaks 1 The tip of the wand should be fairly close to the line You may need to be within 1 4 0 63cm of a small leak to detect it In this case using a second hand to guide the tip along refrigerant lines may be helpful 2 Keep the tip moving along refrigerant lines at a rate of 1 3 inches per second 3 Once the SRL2 indicates a change in concentra tion note the spot on the line and keep the tip moving past the potential leak to refresh the air space within the SRL2 with clean air Note If the SRL2 wand moves through a very high con centration of refrigerant you may need to use in fresh air for 4 seconds before moving to step 4 in order to clear the refrigerant within the SRL2 Comparing Leak Detectors Fieldpiece has two leak detectors The SRL2 uses an infrared IR sensor It detects a CHANGE in concentration so the wand must keep moving The main advantages of the Fieldpiece IR sensor are that its sensitivity will remain the same over the life of the instrument the sensor will last the lifetime of the instru ment it will not tr

9. the other sensitivities levels Beware While in TURBO mode the SRL2 is extremely sensitive and will more easily trigger on abrupt or violent motions as well as very small changes in refrigerant levels Handle with care when in TURBO mode Leak Detection Procedure Keep the SRL2 away from any areas of potential refrigerant leakage until the warm up and calibration period is over The warm up and calibration sequence lasts about 30 seconds after ON OFF is pressed Allow the SRL2 to fully warm up before using to avoid false triggering On startup meter defaults to high sensitivity uick Tips e Keep the wand tip moving past suspected leak locations 2 Once a leak is detected sweep the wand back over to pinpoint 3 To pinpoint larger leaks adjust sensitivity Filter Assessment amp Replacement The filter blocks moisture and other contaminants from the sensor When it gets wet it constricts flow of air and it will have to be replaced Unscrew the sensor tip and replace the white filter so that the rounded end is closest to the tip of the wand Use only the Fieldpiece supplied filter You can order from a distributor extra bags of replacement parts model RFL2 are available from Fieldpiece Model RFL2 contains 10 filters and 5 O rings A WARNING A DO NOT use the SRL2 without the proper fil ter correctly installed The most likely points for refrigerant leaks are at the soldered joints in refrigerant lines and chan
