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.

HOLD will blink under the thermocouple temperature reading. The pressure values can still be changed and the superheat or subcool values will update. The thermocouple can be unplugged from the unit and the temperature reading will remain. Turn the unit off and the temperature reading will be lost. To unfreeze the thermocouple temperature, press HOLD again or turn the unit off. To Change Units 1. With the Subcool/Superheat Calculator off, press the POWER button. 2.

(Figure 2) USB Port Cable Clamp Ribbon Cable Figure 2 NOTE: Putting a rubber band around the case and PC board will help keep it in place. 4. Plug a USB cable into USB Port. (See Figure 2) NOTE: If the ribbon cable pulls out of its clamp, lift up the brown top of the clamp. (Figure 3) Insert the ribbon cable dark contacts down. Push the top of the clamp down to re-clamp the cable.

9. Click on “GET DATA FROM MASTERCOOL WEBSITE”. Once the data is downloaded, the “Download Data to Device” square will turn green. 10. Click on “DOWNLOAD DATA TO DEVICE”. When the download is done, (it only takes a fraction of a second) a window will pop up telling you if the download was successful. NOTE: If the refrigerant is already in the 52246, a pop up window will tell you and the refrigerant data will not be downloaded. 11. After the refrigerant is downloaded, the 52246 will turn off.
