Add and / or change refrigerants: The MFM300 stores P / T data from 15 popular refrigerants
that reside in permanent memory. There is room in the memory for up to five more
refrigerants. New refrigerant P / T data can be downloaded from the Cooper-Atkins website
(www.cooper-atkins.com/mfm.asp) using the MFM300 Toolbox and the optional computer
connection cable.
CALCULATE SUPERHEAT / SUB-COOLING
The MFM300 can be used as a Superheat / Sub-cooling calculator. Connect the temperature
probes to the system and press the SH button. Select the refrigerant and press the ENTER
button. Since there are no pressure transducers connected, system pressure will default to
25 PSI for superheat and 75 PSI for Sub-cooling. You may manually enter the actual pressure
value from the manifold gauge into the MFM300 using the UP / DOWN ARROW buttons. Once
the pressure is entered for Superheat, use the SHIFT button to move to Sub-cooling, where
pressure is manually entered the same way. Remember that the values shown in this mode are
not dynamic.
MEASURE DYNAMIC SYSTEM SUPERHEAT / SUB-COOLING
Measuring dynamic system Superheat or Sub-cooling requires both a temperature probe
and a pressure transducer. The refrigerant type selected on the display must match the
refrigerant type used in the system. Refer to the section Select the Refrigerant. For Superheat
measurement, connect the temperature probe to T1, and the pressure transducer to U1. For
Sub-cooling measurement, connect the temperature probe to T2 and the pressure transducer
to U2. To measure superheat, attach the temperature probe to the system suction line near the
compressor. Attach the pressure transducer to the low side access port. Press the SH button.
