Thermo Scientific
Hb.U: Press the UP or DOWN ARROW to select the holdback value
(in display units).
rmP.U: Press the UP or DOWN ARROW to toggle between ramp
units (SEc, min or Hour). Controller will default to "SEc."
dwL.U: Press the UP or DOWN ARROW to toggle between dwell
units (SEc, min or Hour). Controller will default to "SEc."
Cyc.n: Press the UP or DOWN ARROW to set the number of
program cycles (1 to 999 or cont). The controller will default to
"cont."
SEG.n: Press the UP or DOWN ARROW to select the segment
number (1-8 in 8 segment models, 1-16 in 4x16 models).
tYPE: Press the UP or DOWN ARROW to select the segment type
[End (end of program), rmP.r = ramp rate (ramp to a specified
setpoint at a set rate), rmp.t = ramp time (ramp to a specified
temperature in a set time), dwEll (to maintain a constant
temperature for a set time), StEP (climb instantaneously from
current to specified temperature), cALL (to call a program as a
subroutine, available only on 4x16 programmable models)]. The
controller will default to "End." Other parameters used with tYPE
include; tGt target setpoint), Rate (rate of temperature increase)
and dur (time to target setpoint or time to dwell).
End.t: End segment type: dwELL (dwell continuous), rSEt (reset) and
S OP (End Segment Output power level.
