ATC2000
World Precision Instruments 7
OPERATING INSTRUCTIONS
The temperature controller provides electrically quiet control over the heating plate,
so that you can place the animal directly onto the heating plate.
1. Connect the heating plate to the
Plate connector.
2. Connect the rectal temperature probe to one of the Inputs on the ATC2000 . If it
is an RTD temperature sensor, plug it into the RTD port; if it is a thermocouple
sensor, plug it into the TC port.
3. Turn on the ATC2000 using the power switch on the back of the unit.
4. Adjust the set point, if necessary. See “Setting Temperature Set Point” on page 9.
5.
The unit always powers up in Normal mode with the heat source set as
default heat source from the previous use . Typically, the plate temperature is
the control value used until it reaches the set point. Set the source to the heater
plate, and allow the unit to run until the plate reaches the set point. (See “Setting
Controlled Temperature” on page 8.) The controller’s PID algorithm compares
the controlled temperature to the preset (set point) temperature to determine
the correct heater power output.
6. After the plate reaches the set point, position the animal and insert the rectal
probe.
7. If desired, set the temperature source to the sensor monitoring the animal’s tem-
perature. See “Setting Controlled Temperature” on page 8.
Display
The main display window shows the set point and the mode of operation on the left
side of the screen. On the right side, the control temperature and plate temperature
are visible. The arrow next to the TC Probe indicates that the TC Probe is the
controlled temperature.
Fig. 7—The home page display shows the set point, mode, control temperature and plate
temperature.
TEMPERATURE DISPLAY
In the illustration above, the unit is controlling the thermocouple (TC) probe. In this
case, the RTD probe temperature can be viewed by pressing the Display button.
When the unit controls the RTD probe, that temperature displays on this screen. The
OK next to a temperature indicates that the temperature falls within the parameters
defined by the low and high alarm limits. If the temperature falls below the low limit,
LO displays instead of OK. Likewise, if it exceeds the high limit, HI displays.
If the message “ERROR HI” appears on the Temperature Display, the temperature
probe is either disconnected or defective.
