Sample Auxiliary Thermocouple Temperature and Envelope Setup: This is based on the
following Control settings:
AUX START TEMPERATURE = 25° C (schedule setup page 5 of 5)
AUX PREHEAT TEMPERTURE = 75° C (schedule setup page 5 of 5)
AUX REFLOW TEMPERATURE = 120° C (schedule setup page 5 of 5)
PREHEAT HIGH TEMP LIMIT = +25° C (schedule setup page 5 of 5)
PREHEAT LOW TEMP LIMIT = -25° C (schedule setup page 5 of 5)
REFLOW HIGH TEMP LIMIT = +25° C (schedule setup page 5 of 5)
REFLOW LOW TEMP LIMIT = -25° C (schedule setup page 5 of 5)
RISE1 TIME DELAY = 0.5 SEC (schedule setup page 2 of 5)
RISE2 TIME DELAY = 0.0 SEC (schedule setup page 2 of 5)
The results of these sample settings are shown below.
DATA Key
The DATA key brings up the data screen to the display. The data screen reports the
most recent heat cycle parameters in numerical format: time, temperature, and
counter status (when enabled).
