up or down button will reveal the present setting
of the loop count. This is the number of times
that the entered program will be repeated before
a continuous set point at the last level of the
program is 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 meas-
ured value away from the current set point, ei-
ther 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’”leg-
end is not illuminated but either the “RAMP” or
“DWELL” legend will flash.
