COMPACT SUBCOOL/SUPERHEAT
CALCULATOR
TO GET SATURATION TEMPERATURE WHEN
SATURATION PRESSURE IS KNOWN (PT CHART)
1. Press the POWER ( ) button.
2. Use ▲ and ▼ to display the desired refrigerant.
3. Press ENTER.
4. Press any ARROW button to display the pressure, then use
▲ or ▼ to adjust the saturated pressure.
NOTE: To change the pressure quickly, hold the DOWN ARROW
(▼) button.
5. Read the saturated temperature next to the saturated pressure.
NOTE: For refrigerants that have glide, use the SH/SC
button to toggle between Bubble (BBL) and Dew Point (DP) tem-
peratures.
TO GET SUPERHEAT OR SUBCOOL WHEN THE
SATURATION PRESSURE IS KNOWN
To get superheat, use the low (suction) side saturated pressure
and use a tube on the suction side of the compressor for the actual
temperature.
To get subcool, use the high side saturated pressure and use a
tube close to the outlet side of the condenser for the actual
temperature.
1. Press the POWER ( ) button.
2. Use ▲ or ▼ button to display the system’s refrigerant.
3. Press ENTER.
4. Press any ARROW button to display the pressure, then use
▲ OR ▼ to adjust the saturated pressure.
NOTE: To change the pressure quickly, hold the DOWN ARROW
(▼) button.
5. Insert thermocouple clamp plug into side of unit.
6. Clamp thermocouple onto appropriate tube.
7. Press SH/SC to toggle between superheat or subcool
temperature.
8. Once the temperature has stabilized, read the superheat or
subcool temperature.
NOTE: The unit will not display a negative superheat or subcool
temperature. It will display -- instead. Check the side you are read-
ing your pressure on and the location of the thermocouple clamp.
