Sample program notes:

AUX/POWER CONTROL PORT ON/OFF commands are only necessary when using special order options such as an external relay to control chamber or platform power or an active load under test. COMPRESSOR PORT ON/OFF commands similarly depend on the equipment being controlled having a refrigeration compressor. If the chamber or platform being controlled does not require their use, either of these ports can be configured to control user equipment. Call our technical support department for information.

Step 8 is required because End of Program (substep 3 (next step) = 100) cannot be used in the same step as any of the special commands which use probe numbers 3 and higher.

9.2 Keeping More than One Program in Memory

Programs can be installed and run anywhere there is room within the 100 step (00-99) memory allocation. To install programs at step number xx, press

<DISP/CNTL> xx <DISP/CNTL>.

Example: <DISP/CNTL> 18 <DISP/CNTL> will set the program pointer to step 18, substep 0.
