QUESTempº 44 & 46 models

ACGIH Clothing Corrections

The following clothing corrections are in degrees Celsius. When a clothing correction is
entered into the setup portion of the QUESTemp



46, the value is added to the WBGT

only for looking up the stay times. The WBGT value displayed by the unit does not

reflect corrections.
