9. STEP FUNCTION
When operating in the CALIBRATOR mode, the STEP key will sequentially
recall data stored in memory (up to 10 steps). At each step, the calibrator will
display and output these parameters. The STEP function is non-functional in
METER mode.
10. RAMP FUNCTION: CL25 and CL27
This feature, available only on Models CL25 and CL27, allows the calibrator
to automatically ramp up and down a user-defined staircase. Up and down
keys allow for manual ramping by the user.
To activate the RAMP function, the instrument must first be in the CALI-
BRATE mode. Depress the RAMP key once to enter the ramp programming
mode. The display reads "prog", with memory annunciators 1-4 flashing. A
second hit to the RAMP key starts automatic ramping. A third hit turns off the
RAMP function.
User definable RAMP memory locations 1, 2, 3, & 4 are dedicated to storage
of RAMP parameters; step size, staircase starting point, upper limit, and
lower limit respectively. These memory locations are accessible only when in
RAMP “prog” mode, and are independent of the other 10 memory locations.
Numeric values for RAMP parameters can be set, stored, recalled, and
cleared like other calibrator settings. (Refer page 17, CALIBRATOR MODE
OPERATION).
When automatic ramping is in progress, a hit to either the 7 or 8 key activates
manual up-ramping or down-ramping respectively. Whenever the battery is
replaced (and memory backup is not performed), the ramp parameters
default to factory-set values:
LOC 1 Step Size =10°F (K TC)
LOC 2 Start Point = 500°F
LOC 3 High Limit = 550°F
LOC 4 Low Limit = 450°F
