VIDEO: How to Set the Configuration Parameters for the ATC2000

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.

1.     Press the Config button to access the Configuration menu. Press the Config button again to toggle to the parameter you want to adjust.
2.     Then use the Up or Down button to make an adjustment.
3.     Press the Display button to save the parameter.

Temperature Setpoint

You may adjuSetting Low Alarm Limit
Likewise, you may set the Low Alarm Limit. If the controlled temperature falls below the low alarm temperature limit, the Sensor Alarm LED illuminates. If the audible alarms are enabled, the ATC2000 will also beep continuously until the temperature returns to the acceptable range.st the temperature set point. The default setting is 37°C. The controlled temperature range can be adjusted up to 45°C.

Setting High Alarm Limit

Toggle to the High Alarm Limit. If the controlled temperature climbs above the high alarm temperature limit, the Sensor Alarm LED illuminates. If the audible alarms are enabled, the ATC2000 will also beep continuously until the temperature falls back into the acceptable range

Setting Low Alarm Limit

Likewise, you may set the Low Alarm Limit. If the controlled temperature falls below the low alarm temperature limit, the Sensor Alarm LED illuminates. If the audible alarms are enabled, the ATC2000 will also beep continuously until the temperature returns to the acceptable range.

Enabling Audible Alarm

To change the audible alarm settings, toggle to Audible Alarm. By default, alarms are disabled on startup, because they would beep continously until the controlled temperature stabilizes. When the audible alarm is enabled, the controller will beep if the controlled temperature falls outside the range set by the high and low alarms.

Setting Temperature Offset

If desired, you may set temperature offsets for the RTD probe, the thermocouple probe and the heater plate. The temperature may be offset by ±5˚C. For example, if you set the plate offset to 3.0˚C, the ATC2000 will control to the new 37˚C, which is actually 34˚C plus a 3˚C offset.

• Set RTD Offset- Adds temperature offset to the RTD probe reading
• Set TC offset- Adds temperature offset to the thermocouple probe reading
• Set Plate Offset- Adds temperature offset to the heating plate reading.

Enabling Adaptive Mode

In the adaptive mode, the sensor in the heated plate is used as the control trigger for the set point. A platinum sensor in the plate monitors the plate temperature very precisely. The temperature of the subject, using the selected probe is sampled at regular intervals. The difference between the temperature of the subject and the desired set point is used to control the heating of the plate.

Toggle to Adaptive Mode Enable to adjust the parameter.

Once the adaptive mode is enabled, Adaptive appears as the mode on the main display window.

If you press the Display button again, the alternate temperature displays along with a timer that counts up from the last sampled time. In this case, the temperature was sampled 5 minutes and 42 seconds ago. If the interval is set to 10 minutes, the temperature will be sampled again in 4 minutes and 18 seconds.

Setting Adaptive Interval

If you enable the adaptive mode, you may set the adaptive interval. The sampling interval for the adaptive mode should be set long enough to allow the subject and plate to stabilize before the temperature is sampled. The default sampling rate is 3 minutes.

Changing Shutdown Temperature Set Point

The ATC2000 automatically goes into shutdown mode if the plate temperature exceeds 45°C. This is designed to prevent overheating the subject. In shutdown mode, the source temperature defaults to the temperature sensor embedded in the heating plate. The shutdown mode has its own shutdown temperature set point, which is different than the temperature set point in normal mode. By default, the shutdown set point temperature is set to 37ºC. You may set it between 20.0ºC and 45.0ºC.
To clear the shutdown mode, hold down the Up and Down buttons on the front panel simultaneously for 2 seconds. Shutdown mode may also be cleared by momentarily powering down the ATC2000 for 2-3 seconds. Either procedure causes the ATC2000 to revert to the normal mode.
