The ATC2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. It has three modes of operation, which we discuss here.
Normal mode compares the temperature and the setpoint for PID control. Adaptive mode is ingenious. It uses the monitored animal temperature and the actual plate temperature to define an offset value which is used to adjust the PID parameters. That offset is recalculated at a set interval for extremely precise control. Shutdown mode is a fail safe that shuts the unit down if the plate temperature reaches a defined setpoint (like 45ºC) that would endanger the animal.

REMS AutoSampler is an automated TEER measurement system that uses a robotic arm to make measurements in 24- and 96-well plates. This article details how to upgrade the software for a REMS system.
Considerations Before You Begin
The first consideration is the hardware in your REMS system and the software version you are running.
Systems Older than 2014
- If your system was purchased before 2014, the REMS will have a PCI6023 data card, and you may only upgrade to the REMS4 software. See below for instructions on verifying your software version.
- To upgrade to the current version of the REMS software (REMS6.02), a unit purchase before 2014 will need a PCI6220 data card. You may purchase the upgrade kit (WPI# 300555), which includes the board/data card (for example, NI PCI6220), a new interface cable and software version 6.0.2.
In addition, you need a newer computer with free PCI slot. WPI’s current REMS computer...more

The ATC-2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. The ATC-2000 uses a digital PID controller to regulate the application of power to the heating plate to achieve the desired temperature at the monitored sensor. PID stands for Proportional, Integral and Differential. If the factory default PID settings do not adequately stabilize the system, you can manually adjust the PID parameters. WPI doesn't reccomend changing these parameters manually unless you are familiar with the functions of each PID parameter.

ATC2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. Here we will look at how to adjust the basic configuration parameters. From the configuration menu, you can:
- Adjust the set point temperature
- Set the high and low alarm limits
- Enable/disable the audible alarm
- Adjust the three temperature offsets
- Enable adaptive mode and setup the adaptive interval
- Change the shutdown temperature setpoint
You can use the same procedure to adjust any ATC2000 configuration parameter, regardless of which parameter you’re adjusting.
- Press the Config button to access the Configuration menu. Press the Config button again to toggle to the parameter you want to adjust.
- Then use the Up or Down button to make an...more

ATC2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. The ATC2000 has three temperature sensors. One is located in the heated plate, and the other two can be plugged into the RTD and TC input ports. The ATC2000monitors all three temperature readings. You can choose which of the three the unit will control. The ATC2000 then heats (or stops heating) the plate to keep the controlled temperature within the alarm limits.
