TestEquity 123C Temperature Chamber
Purge Operation
The Purge
mode is enabled through the Purge button on the F4T controller or Event 2 (Digital
Output 2) in the F4 Controller.
Adjusting the Purge Flow
A flowmeter is located on the front panel to adjust the flow of purge gas into the chamber. The
flowmeter has a scale, calibrated in SCFM. The flow of purge gas should be adjusted to the
minimum amount required to obtain the desired drying in the chamber for your particular
conditions. A suggested starting setting is 2 SCFM.
Relief Vent
Excess pressure in the chamber workspace is vented through a pressure-relief check-valve,
which is located within the electrical compartment. There is no need to vent this externally.
