Operating
Users and operators of this oven must comply with
operating procedures and training of operating
personnel as required by the Occupational Safety and
Health Act (OSHA) of 1970, Section 5 and relevant
safety standards, and other safety rules and
regulations of state and local governments. Refer to
the relevant safety standards in OSHA and National Fire Protection Association
(NFPA), Section 86 of 1990.
Chamber temperature is set and maintained by the control panel and control circuitry.
This combination results in a constant, controlled, manually-selected chamber
temperature. In addition, the controller can be programmed to obtain a series of preset
temperatures and time durations. Also available are computer interface accessories
which allow the chamber to be controlled from a host computer.
In the event of a controller malfunction, the chamber and test object are protected from
excessive temperatures by two over-temperature safety thermostats. One of the over-
temperature thermostats is adjustable and is located on the front panel of the chamber.
The other over-temperature thermostat is factory calibrated and is mounted behind the
chamber rear panel.
Controller Power Up
Power to the controller is supplied through the chamber. The HEAT and COOL lights
(LEDs 1 and 2) will come on and the controller will immediately begin to reach the set
point temperature when the chamber POWER switch is turned on.
WARNING: WARNING: Do not use oven in
wet, corrosive or explosive
atmospheres unless this oven is
specifically designed for a
special atmosphere.
