HOW THE DRSA WORKS

• Pressure readings for the low and high sides
• Pressure fluctuations down to 1/4 psi
• Bubble and dew (or saturation) temperatures for up to 23 selectable refrigerants.

The patented bar graph display shows the smallest modulations about the digital reading. This allows unprecedented diagnostic power, as dynamics of valve modulation and refrigerant flow are easily visible to the technician.

• Bar graph: segments show changes from digital reading
  • Range: ±2psi low-side, ±8psi high-side
  • In example above, low-side has dropped 2psi to 63.9psig since update, high-side has dropped 3psi to 170psig since update
• Resolution: ¼ psi low-side, 1 psi high-side
• Temperatures: corresponding bubble and dew points for current pressures
• Refrigerant: Current selection on bottom left
  • Selectable ASHRAE / trade number mode (eg. "R-410B" vs "66" for MP66)

• R-? selects active refrigerant
• ZERO automatically calibrates to current atmospheric pressure
• ENG / SI changes between English (PSI, "Hg, °F) and SI (kPa, °C) units
• GA / ABS changes between PSIA and PSIG for English units
• 1SEC / 5SEC / HOLD changes the rate digits are updated
• LCD / changes contrast to fit lighting conditions
• MIN/MAX CLR clears peak pressure memory
• MODE selects between Temperature, Superheat, Subcooling, and pressure memory modes
• t, SH, SC, HI or LO on the lower right shows current mode and reading
