YJACK VIEW® provides seamless integration with YJACK® and TITAN® devices offering a complete HVAC/R diagnostic solution (hardware purchase required). Supported Hardware: TITANMAX® Digital Manifold YJACK PATH® Range Extender YJACK® Temperature Clamp & Strap YJACK DEW® Psychrometer YJACK PRESS® Pressure Gauge YJACK VAC® Vacuum Gauge YJACK AMP® Current Probe YJACK MANO® Manometer YJACK FLOW® Anemometer P51-870 TITAN® Digital Manifold 68864 Wireless Refrigerant Scale 6860x Combustion Analyzer Receive and analyze live data including pressures, temperatures, vacuum level, psychrometric data, duct air flow and speed, duct pressure drops, fuel pressure settings, weight readings, and electrical current. CREATE/MANAGE/SHARE SERVICE REPORTS Create customizable PDF reports of system measurements and service information while storing past jobs and reports. The user profile feature stores user information that is automatically generated in the header of each report. ENHANCED DATALOGGING Record data from one or all current session types as desired. Choose from a variety of sampling rates depending on user need. Live updates to selected devices, units, elevation, refrigerant selection appended to existing data logs. Start and stop datalogging at will, save for later, or share via email for remote analysis. PRESSURE / TEMPERATURE View System Pressure and Temperature data on up to 4 systems at once. Select refrigerants for calculating system properties including saturation temperatures and system superheat/subcooling. Manipulate data view types, including large number format, analog gauge (pressure only) or line graph. STATIC PRESSURE Select and record pressure drops across multiple different locations like the filter, the coil, external static pressures, and gas pressure readings to upload into a report for the customer all in one session. EVACUATION Monitor system vacuum as reported by a TITAN® digital manifold, wired vacuum sensor or the YJACK VAC® Wireless Vacuum Gauge. Adjustable Vacuum Pressure Target and Hold timer ensures all refrigerant, moisture, and non-condensable gases are removed during evacuation. LEAK TEST Monitor pressure changes during pressurized leak testing to verify that system is tight. PSYCHROMETRICS Analyze psychrometric data on up to 4 systems at once. Ensure maximum home comfort through wireless supply and return relative humidity, dry bulb, wet bulb, dew point temperatures and enthalpy calculations. Compare system rated capacity to actual output for overall system efficiency. CHARGING & RECOVERY Display scale readings from the Wireless Charging Scale to accurately charge systems or determine system charge amount through recovery. View readings from your Wireless Refrigerant Scale with simultaneous gross weight and weight change fields. ELECTRICAL Electrical session displays readings from YJACK AMP® Wireless Current Probe while monitoring AC current and inrush. These readings are used for calculating power draw and EER. ANEMOMETER Anemometer session displays readings from YJACK FLOW® Wireless Anemometer Probe. Quick one-line verification from duct-to-duct comparison or full system calculations using AHRI40 standard for air measurement, to compare installed system airflow to published standard. AVAILABLE DEVICES Monitor the data and battery life of your devices. Create a perimeter of devices by placing YJACK PATH® devices periodically around the work area, boosting the signal of all nearby devices. COMBUSTION Capture results from your combustion analyzer and include the data in your job report.
