STANDARD OT & TXV SYSTEM TEST

Refer to figure D-1, Below 

•

Hook up TMX3C Clamp-on probe or TMX2S Velcro Strap-On temp probes as

follows: Channel A to inlet and channel B to outlet of evaporator*/condenser (*use

optional TMX2FP Flex Surface Probe on evaporator inlet for vehicles like GM S-10

and Ford Trucks where orifice tubes are mounted at the evaporator inlet). 

•

Hook up either TMX2A Moving Air probe or TMX2GA General Purpose Air probe

from channel C to monitor ambient temperature 1-2' in front of the condenser. 

•

Hook up a second air probe from channel D to check vent air temperature in the

vent closest to the evaporator

•

Hook a RH (Relative Humidity) probe to the AUX port. Vent temperatures will

increase significantly as humidity levels rise, so this will allow you to follow the

OEM specifications for minimum vent temps based upon ambient air temp and

RH level.

VARIABLE DISPLACEMENT COMPRESSORS

The compressor control valve may mask a refrigerant undercharge when checking

max heat load in the service bay. The recommended practice is to assure that the

compressor is commanded to a 100% duty cycle during testing. Various methods are

available to perform this function.
