Rate Of Change To calculate rate of change for a particular condition, take the difference between the Start Temp and End Temp and divide by the Transition Time. Cool Down Example (empty): From +85°C to -10°C = 95°C / 14 min = 6.8°C/min. Cool Down Example (with 25 lb. load): From +85°C to -10°C = 95°C / 22 min = 4.3°C/min. Heat Up Example: From -35°C to +85°C = 120°C / 16 min = 7.5°C/min. *Note: Transition times are measured after a 2-hour soak at the respective start temperature with an empty chamber, as indicated on the temperature controller, 23°C ambient. Measured with setpoint beyond the start and end temperatures. Does not include the effect of proportional band when approaching setpoint. Performance is reduced by 17% with 50 Hz input power.

Instrumentation
Temperature Controller	Watlow F4T Touch Screen Controller with RS-232, Ethernet interface, 4.3" color graphic touch screen. OR... Watlow F4 Controller with RS-232 interface, LED readout of temperature, LCD display of other parameters.
Limit Controller	Independent high and low temperature limits. Triggers an audible alarm and shuts down the chamber. Relay contacts provide a safety npower interlock for test sample.
Chart Recorder	(Optional) Honeywell DR4300 Series. One pen, 10" circular chart. Mounts in lower front door.

Input Power Requirements
230 V ±10%, 60 Hz, 1 PH	Max Current Draw 22 A; Recommended Service 30 A
208 V -5/+10%, 60 Hz, 1 PH	Max Current Draw 22 A; Recommended Service 30 A
Input may be configured for 230 V or 208 V in the field by changing jumpers. Single phase input only. Call for other voltages or 50 Hz operation. Performance is reduced by 17% with 50 Hz input power. Customer power source must be hard-wired to the chamber by a qualified electrician. Power cord and plug are not included.

NOTE: Performance is typical and based on operation at 23°C (73°F) ambient and nominal input voltage. Designed for use in a normal conditioned laboratory. Operation at higher ambient temperatures may result in decreased cooling performance. Additional ports and shelves will also affect performance. Operation above 30°C (85°F) or below 16°C (60°F) ambient is not recommended.
