9 SuperHeat
This character set of the display is the superheat reading, in either °F
or °C. If temperature reading lower than the low-side dew point for
the selected refrigerant, SH is negative.
10 SuperHeat Temperature (lowside sensor)
The is the actual temperature being measured by the Superheat sensor
on the line it is mounted on.
11 SubCool Temperature (highside sensor)
This is the actual temperature of the highside sensor on the line it is
mounted on.
12 Delta T
This is the differential temperature of the highside sensor temperature
minus the lowside sensor temperature should you want to take a ‘delta
T’ differential reading.
When the MODE key is toggled the dt will then disappear and either
the HI or LO will appear to:
• HI
Maximum pressure recall mode: pressure fields display
highest pressures sensed since threshold reset, and their
associated saturation temperatures. In this mode, the
15-min automatic shutdown is disabled.
• LO
Minimum pressure recall mode: pressure fields display
lowest pressures sensed since threshold reset, and their
associated saturation temperatures. In this mode, the
15-min automatic shutdown is disabled.
Keys
PWR
This key turns unit on for a period of 15 minutes. If it is pressed
again while the unit is on, the unit will turn off.
• To disable automatic shutdown, hold UNIT while pressing PWR
to turn the unit on. "Pr" will be shown on the screen. Press PWR
to continue.
• Automatic shutdown is disabled when in HI or LO modes.
