changed states. This feature allows for minimal block temperaturescanning

times and improved accuracy.

Example 2:

With theinstrument displaying 25°C, set the set-point to 100°C and enable the

Scan Hold feature. When the thermal switch changes states at50°C, the con-

troller automatically sets a new set-point of 50°C and the status flashes either

"o or c".

Note: There is a delay between the displayed temperature and the actual tem-

perature of the thermal switch. Toachieve better accuracy when the thermal

switch is tripped, the scan rate should be set for a slower time. The slowerthe

scan rate the more time required to perform a test. The operator must determine

the optimal scan rate for the specific application.

6.5 Ramp and Soak Program Menu

The ramp and soak program feature allows the user to program a number of

set-points and have the dry-well automaticallycycle between the temperatures,

holding at each for a determined length of time. The user can select one of four

different cycle functions.

The program parameter menu is accessed by pressing “SET” and then “UP”.

6.5.1 Number of Program Set-points

The first parameter in the program menu is the number of set-points to cycle

through. Up to 8 set-points can be used in a ramp and soak program.

Pn=8 Number of program set-points

Use the “UP” or “DOWN” buttonsto change the number from 2 to 8.

Pn=3 New number of program set-points

Press “SET” to continue. Pressing “EXIT” causes any changes made to the pa-

rameter to be ignored.
