LRA Inrush
The UEi LRA Inrush is programmed to properly capture the starting current for
compressor motors.
• Select AC Amps
• Select the range capable of capturing the maximum value
• Press and hold LRA Inrush for two seconds – INRUSH will now be shown
on the screen
• Activate compressor and read value on the display
• Press and hold LRA Inrush for two seconds to exit
