Calibration of the reference machines
Wascator FOM 71 CLS
12. Temperature control
Use temperature control program 994. Put a temperature probe through the
upper door gasket into the bath or use the laboratory temperature measure-
ment system (must be calibrated separately in advance). Read the temperatu-
res at 25°, 40°, 60° and 80° on the machine display and on the measurement
instruments.
Max. deviation ± 1°C.
13. Drum speed at wash. ***WARNING***
Remove the back panel. Run program 991.
The wash speed shall be measured with a speedo meter (reflector type).
The reflector shall be placed on the big pulley. Wash speed shall be measured
at nominal voltage and with a load of 5 kg of cotton as load.
Speed variation allowable in both directions: 52 ± 1 RPM.
14. Extraction speed ***WARNING***
Proceed as in 13, but rapid advance to last drain after wetting the load and
measure the extraction speed with a well balanced load of wet cotton (dry
weight 5 kg) after reaching set speed 500 rpm.
Extraction speed shall be within 500 ± 20 RPM.
15. Recording of complete program (not compulsory)
Record using the laboratory recording equipment the complete IEC 60° cotton
program. For best calibration accuracy use no load.
Parameters to be recorded as a function of time:
Temperature
Amount of water
Speed
