Table 1-1. Safety InformationCautionTo avoid damage to equipment, follow theseguidelines: Do not allow pressures beyond the specifications listed in this manual. Be aware that internal pressures canchange unintentionally when equipment isstored with pressure in the system duringtemperature changes. If sub-cooled liquidrefrigerant is trapped in a hose or manifoldwith no room for expansion, it may result indramatic pressure variations with seeminglysmall temperature changes. Pressures canreach high enough levels to cause damage to the instrument’s internal pressuretransducers. Release liquid refrigerant fromthe hoses and manifold when disconnectingfrom a system. Refer to cautions supplied with batteriesacquired for use in this instrument. Do not attempt to introduce liquid orsamples heavily laden with oil into theinstrument. Read and observe instructions and specifications related to the batteries used in thisinstrument that may cause damage to it.Chapter 2Getting AcquaintedIntroductionThis instrument will clearly and accurately reportcritical information needed to properly service refrigeration and air-conditioning equipment. With itsmany features, time can be saved and the qualityof service can be verified through data reports forcustomer satisfaction. Some of the most significant features include: High accuracy and resolution Very fast and sensitive leak detection Robust temperature compensation with faultdetection Data logging and downloading for reporting andanalysis High durability and weather-resistanceNote that these instructions do not cover themanifold attached to the instrument.Turning the Instrument Onand OffPress and release thekey to turn unit on. Afterthe logo appears briefly, the instrument will present the main menu.Press and hold theunit off.key ( two seconds) to turn Do not use this instrument on systemscontaining leak sealing chemicals. Theseleak sealants can collect and harden in theinstrument, causing permanent damage.Table 1-2 SymbolsImportant informationPower On/OffT1Temperature 1T2Temperature 2RECIndicates that the instrument isrecording readings (data logging) Indicates page-by-page scrollingmode (during data log playback)BatteryBattery connector orientation4Figure 2-1. Menu DisplayBattery ConsiderationsThe instrument uses eight AA batteries. Theuser may select batteries of the following types:Alkaline, AA-Lithium, Ni-MH, Ni-Cd, Li-Pol, Li-Ionfrom the Setup menu (see Chapter 5). Do not mixbattery types, including rating (i.e., do not mix fourNi-MH rated at 1600mAh with four Ni-MH ratedat 1800mAh). Also, each battery in a set of eightmust be at the same power state, preferably fullycharged. The battery life indicator is only accuratewhen the correct battery type is selected in theSET-UP menu.
The illustration below shows three bars that indicate a fresh or well-charged battery pack. Whenthe battery weakens, the bars will disappear oneby-one as the battery power decays. When onebar remains, the symbol will turn yellow. When allbars are gone, the batteries are nearly dead andthe symbol will turn red. The unit will briefly showa pop-up message just before the unit stores alldata and then automatically shuts off.Maximizing Battery LifeBattery life decays fastest when the DIGITALMANIFOLD display is selected, the vacuum sensor is attached, and the backlight is on. Batterylife during data logging is maximized by usinghigh-performance batteries, detaching the vacuumsensor (if not in use), and a short Power SavingMode time setting is selected.Keyboard KeysFigure 2-2.

Using the Temperature andVacuum SensorsChapter 3Getting the Job DoneTo use the external temperature and vacuum sensors, plug them into the connectors located on theside of the instrument. The use of rubber connector boots is optional. They will, however, increasethe weather resistance of the unit and reduce theamount of dust that could enter at the vacuumconnector, if that boot isn’t used. When not in use,the vacuum and USB connector openings shouldbe covered with the tethered plugs.Temperature andPressure ModeNote: A common mistake is to forget to zero thepressure sensors before using the instrument fora job, resulting in incorrect pressure readings andcalculations. See Chapter 5 - Settings, Zero pressure, for more information.The unit will simultaneously display inputs fromfour sources: T1 Temperature Sensor (Suction linetemperature for superheat) T2 Temperature Sensor (Liquid linetemperature for subcooling) Low Side Pressure Transducer (internal) High Side Pressure Transducer (internal)T1T2Vacuum(Plugged)USB(Plugged)Figure 2-10. Sensor ConnectionsTemperature Probes – The system analyzer willdisplay readings from any K-type thermocoupleprobe with a miniature styleconnector (see picture). TheK-type is usually indicatedwith a letter K on the connector. The miniature stylethermocouple connectorshave two flat blade contacts. The two blade contacts are different widths to ensure proper polarity.Plug the blade contacts into the matching slots inthe analyzer.Your system analyzer includes a pair of K-typeclamp probes for easy pipe temperature measurement.Figures 3-1, 3-2, and 3-3 show the three digitalmanifold displays for monitoring system chargingand operation.Figure 2-11. Sensors without Boots The first display (see Figure 3-1) presentsall available data outputs including XYTime-Pressure charting. The second display (see Figure 3-2) is thesame as the first except for the exclusion ofthe Temp-1, Temp-2, vapor (Low sat.) andliquid (High sat.) saturation points. The third display (see Figure 3-3) is the sameas the first except for the exclusion of the XYTime-Pressure charting.Once the default digital manifold display has beenselected from the main menu, pressing the “Enter”key will advance through all three displays.Figure 2-12.
