With half duplex the commands are executed but not echoed.
9133 User’s Guide be altered. The correct values are important to the accuracy and proper and safe operation of the instrument. Access to these parameters is available to the user so that in the event that the controller memory fails the user may restore these values to the factory settings. The user should have a list of these constants on the Report of Calibration that ships with the instrument. Caution: DO NOT change the value of the instrument calibration constants from the factory set values.
8 Digital Communication Interface 8 Digital Communication Interface The 9133 calibrator is capable of communicating with and being controlled by other equipment through the digital interface. With a digital interface the instrument may be connected to a computer or other equipment. This allows the user to set the instrument temperature, monitor the temperature, and access any of the other controller functions, all using remote communications equipment.

9 Calibration Procedure 9 Calibration Procedure Sometimes the user may want to calibrate the instrument to improve the temperature set-point accuracy. Calibration is done by adjusting the controller probe calibration constants R0, ALPHA, DELTA, and BETA so that the temperature of the calibrator as measured with a standard thermometer agrees more closely with the set-point. The thermometer used must be able to measure the well temperature with higher accuracy than the desired accuracy of the calibrator.

9133 User’s Guide Problem Possible Causes and Solutions The display shows any of the following: err 1 , err 2 , err 3 , err 4 , err 5, Err 6, or Err 7 Controller problem. The error messages signify the following problems with the controller. Err 1 - a RAM error Err 2 - a NVRAM error Err 3 - a Structure error Err 4 - an ADC setup error Err 5 - an ADC ready error Err 6 – a defective control sensor Err 7 – a heater error Initialize the system by performing the Factory Reset Sequence describe above.
11 Troubleshooting Problem Possible Causes and Solutions Emissivity is not the same as the IR probe and target. Adjust The IR probe does not read what the IR the IR gun or use a look up table from the IR probe manufacturer. heat source indicates Ice is on the target. Heat the unit above 5°C and remove the water. Ambient light may change the reading of the IR probe. Get closer to the target. A channeling tube may remove some external environmental factors.
