achieved. By pushing the up or down button the number of loops can be set at any value from 1 to

999.

Set the Holdback Feature

5. Scroll through the main scroll list until "HB" is displayed. Push the up or down button to reveal the

current value of holdback. The up or down button can now be depressed to scroll to the required

value. Holdback is set in display units and represents the allowable excursion of measured value

away from the current setpoint, either above or below, before the program is forced into hold. The

program will remain in hold until the measured value comes within holdback limits. This feature is

active the whole time that the program is running. When hold is forced onto the program by holdback,

the "HOLD'"legend is not illuminated but either the "RAMP" or "DWELL" legend will flash.

Implementing Programs

Program Execution

Once the program has been entered it can be set running by depressing the ‘RUN/HOLD' push button on

the front.

NOTE

Be sure to select the program number before pressing "Run/Hold."

With the run initiated, the program will commence and the legend on the display will indicate if a ramp or

dwell is being performed. While a program is running the short scroll will contain a third parameter "TIME."

Push scroll button once; time remaining for the current segment, either ramp or dwell will be indicated. If

the loop counter has been set to any value other than one, then the above procedure will be repeated for

each loop.

At the end of the complete program, an "E" will appear on the display.

Parameter Change While Running

The previous parameters can be inspected but not changed while a program is running. If it is necessary to

alter a parameter while a program is running, the program must be placed into the hold condition. To put

program into hold, push run/hold button once. After modification of the parameter, returning the program

to the run state will cause the program to continue with the changed value(s) installed. Push run/hold

button again to restart program.

Loop Count

If the loop count is set to values other than one, then the number of loops remaining in a running program

can be displayed. To determine which loop is being performed depress scroll button until LR' is displayed

and by pushing either the up or down button the remaining number of loops, excluding the one being

executed, is displayed.

Program Hold

A running program can be forced into hold at any stage by depressing the "RUN/HOLD" push button on

the front. When a running program is forced into hold, "HOLD" legend will appear on the display together

with the segment type and will be flashing. Pushing "RUN/HOLD" button again will return the program to a

run situation and extinguish the "HOLD" legend.

Program Reset

A running, held or finished program can be reset by depressing the up and down push buttons together.
