As an option, your chamber may be provided with either a circular or strip type chart recorder to record
temperature versus time. This recorder is typically a one-pen type, which also digitally displays the process
value. A 100 ohm platinum RTD is used for temperature measurement. It is placed in the discharge air of the
chamber plenum.
The recorder configuration is documented in the Test Report, which is located in the Supplemental
Instructions Section. Reference the recorder’s user manual for a detailed operation of the unit.
