Take electrical current measurements and analyze critical system power information with the YJACK AMP Wireless Current Probe 67067 by YELLOW JACKET. The durable and compact clamp provides accurate readings even in hard-to-reach areas. Inrush current of system compressor can be measured to analyze hard starts. The system electrical input can be compared to the heating/cooling output to calculate the Energy Efficiency Ratio (EER).

Launch the YJACK app, select the desired settings and Electrical session type (requires app version 3.1 or later). There is no Bluetooth pairing required.

1. Tap on readings box to select YJACK AMP™ device readings to be displayed and desired view type

2. Tap the grey banners to expand or collapse data sets

3. Measure Inrush current and elapsed time since inrush measurement

4. Enter system voltage for power calculation

5. Use power consumption and system capacity to calculate Energy Efficiency Ratio (EER)

YJACK for more Connected Techs

The YJACK Series is a network of devices that form a new platform offering a total HVAC/R diagnostics solution. Multiple devices can measure system and environmental parameters, providing a complete picture of a system’s condition. Each device utilizes Low Energy Bluetooth (BLE) technology to interconnect with each other and any smart device, Android or iOS. Many of the YJACK Series devices can also communicate directly with the P51-870 TITAN Digital Manifold simultaneously.

The YELLOW JACKET YJACK VIEW App provides seamless integration with YJACK and P51-870 TITAN devices offering a complete HVAC/R system diagnostic solution. Just use your YJACK and P51-870 TITAN devices with your smartphone for complete system analysis.
