Users Manual
The SOAK TIME parameter is used to set the number of
minutes each setpoint temperature is held before it
changes to the subsequent setpoint. Soak time starts
when the temperature is stable.
The NO. CYCLES parameter is used to set how many
times the setpoint sequence is to be done again.
The DIRECTION parameter is used to set how the
setpoints sequence before the sequence is done again.
When set to →, the Product does the setpoints in one
direction from 1 to 8. If set to , it does the setpoints from
1 to 8 and then back to 1 before the sequence is done
again.
RUN PROG Function
Use the RUN PROG function to start and stop the test set
up through the RAMP/SOAK menu. With the TEST
STATUS parameter highlighted, push or to change the
test status and push . When set to RUN, the furnace
uses the values set through the RAMP/SOAK menu to
control the furnace. When the furnace does all the values
in the RAMP/SOAK parameters, the status changes to
OFF. To stop a test, set the parameter to OFF.
Calibration (CALIB) Menu
Calibration parameters must be correct for the
Product to operate correctly.
The CALIB menu lets you get access to the calibration
points constants and the controller parameters.

Note
Calibration (CAL) Points Menu
When you push the CAL POINTS softkey, the product
prompts you for a numeric password. You must know the
password before you can change a calibration point.
There are 12 calibration points: Zone 1 (300), Skew 1
(300), Temp 1 (300), Zone 2 (700), Skew 2 (700), Temp 2
(700), Zone 3 (1000), Skew 3 (1000), Temp 3 (1000),
Zone 4 (1200), Skew 4 (1200), and Temp 4 (1200).
The TEMP parameter adjusts the actual temperature at
the midpoint location for the applicable set-point
temperature, but does not change the temperature
gradient. The ZONE parameter increases or decreases the
temperatures in the outer areas of the access tube for an
applicable setpoint temperature. The curvature of the
temperature profile is adjusted, and does not have an
effect on the temperature at the midpoint location or the
slope of the temperature profile at the midpoint location.
The SKEW parameter adjusts the slope of the temperature
profile at the midpoint location for the applicable setpoint
temperature. This increases the temperature of one end of
the access tube and decreases the temperature of the
opposite end.
