Features and Use
General
The unit performs the following tasks:
• Sense and display pressures present in the manifold
• Calculate and display dew / bubble points corresponding to the
sensed pressures, for the selected refrigerant
• Sense and display temperature of probe tip
• Calculate and display system superheat or subcooling, based on
sensed pressure and temperature, for the selected refrigerant
• Displays maximum and minimum pressures observed since
threshold reset
The unit has two 1/8" pressure ports, acting as two gauges: blue for
low side, red for high side. All settings are controlled through the
keypad and affect both sides of the display.
Some features of the unit include:
• Working pressure ranges:
Low side: 0-200psia (1350 kPa, 13.5 bar)
High side: 0-550psia (3000 kPa, 37.9 bar)
• Sensing resolution (precision):
Low side: 0.25psi or 0.4"Hg (2kPa, 0.02 bar)
High side: 1psi (7 kPa, 0.07bar)
