Description
The SLICE-QT is a high-precision temperature controller (see figure 1).
Purchase Includes
- SLICE-QT Temperature Control Unit
- AC power cord with appropriate wall plug for you location (if known)
- Four single-ended 6-ft control cables1)

Potential for electrical hazard. |
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 Detail screen.
- Touch Settings > Load Limits
- Set the Current and Power limits for you transducer.
- Touch the Return icon.
- Touch Settings > Plant
- Enter in the parameters for your thermistor.
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.
- When choosing TEC/Bipolar, also select Negative of Positive Polarity,
- Using table 1, make connections from the SLICE-QT to your thermal plant via the cables 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 inside 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 entry module.
- Touch a Channel Label icon to enter the Channel Details screen.
- Touch the Setpoint Temperature Icon to enter in the desired set point temperature.
- Touch Settings > Limits
- Set the absolute minimum and absolute maximum temperature allowed for your plant.
- Set the lock range. This range determines over what value of ∆T = Tact - Tset the system is 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 > PID
- Set the PID parameters for your plant
- Touch each window to set the given parameter
- We recommend the Ziegler-Nichols method of setting your PID parameters2)
- Touch the OFF icon to engage the temperature servo
- Monitor on the performance screen to ensure system settles
Use caution grounding the shield at the transducer end of the interface cable as ground loops may be formed, degrading performance. |
You may purchase more cables separately from Vescent Photonics. We do not recommend making cables, but if you do so, make sure the metal sleeve (drain) is well.
The SLICE-QT will accept input line voltages within the ranges in table 2.
