Getting Started
When presented with a given view, it is possible to select the functionality or change the values
in any field bordered in blue. When a particular field is actively being edited, its border will be
yellow.
From the Home screen, touch the CH icon for the channel to be used to go to the Channel Detail1.
screen.
Touch Settings > Load Limits2.
Set the Current and Power limits for you transducer.1.
Touch the Return icon.2.
Touch Settings > Plant3.
Enter in the parameters for your thermistor.1.
Note: Enter EITHER Beta, Reference Temperature, and Reference Resistance OR the
Steinhart-Hart Constants, A, B, and C. The other set of parameters will be automatically
calculated.
Select the Transducer Type: either TEC/Bipolar or Heater/Monopolar.2.
When choosing TEC/Bipolar, also select Negative of Positive Polarity,3.
Using table 1, make connections from the SLICE-QT to your thermal plant via the cables4.
supplied by Vescent. Peel the drain (shield) back to make connections. The shield is grounded
at the SLICE-QT. Use caution grounding the shield at the transducer end as ground loops may
be formed, degrading performance.
Use the supplied AC power cord to provide power to the SLICE-QT. The power converter inside5.
the unit will accept any line voltage within the range in table 2.
Turn on the SLICE-QT with the power switch on the back of the unit located on the power entry6.

Touch a Channel Label icon to enter the Channel Details screen.7.
Touch the Setpoint Temperature Icon to enter in the desired set point temperature.8.
Touch Settings > Limits9.
Set the absolute minimum and absolute maximum temperature allowed for your plant.1.
Set the lock range. This range determines over what value of ∆T = Tact - Tset the system is2.
considered to be locked. If ∆T is outside of this range, the Error field will change from
green to yellow. This range will appear as yellow dashed lines on the plot of ∆T vs. time
on the Channel Detail screen.
Touch Settings > PID10.
Set the PID parameters for your plant1.
Touch each window to set the given parameter1.
We recommend the Ziegler-Nichols method of setting your PID parameters2) 2.
Touch the OFF icon to engage the temperature servo11.
Monitor on the performance screen to ensure system settles12.
Use caution grounding the shield at the transducer end of the interface cable as
ground loops may be formed, degrading performance.
