AM8060 Precision Thermometer User’s Guide 5 Instrument Calibration And Accuracy Adjustments AM8060 is designed for temperature measurement by measuring the probe resistance and converting it into a temperature. Consequently, the resistance measurement is very critical, and the instrument must be calibrated correctly. Every AM8060 is calibrated before shipment. AM8060 needs regular calibration performed by qualified professionals. One year calibration interval is recommended.
AM8060 Precision Thermometer User’s Guide 5.1 100 Ω calibration 5.1.1 Turn off the power, put the measurement/calibration switch to the “CAL”side (right side). Please see Figure 3 for details. 5.1.2 After turning on the power,AM8060 shows the calibration main menu. It can be seen that there are two calibrations required: 100 Ohm CALIBRATION and 25 Ohm CALIBRATION. The following is an illustration of 100 Ohm CALIBRATION.
AM8060 Precision Thermometer User’s Guide * 100 Ohm CALIBRATION ------------------------------------------Connect a 100 Ohm Standard Resistor and Press Enter Menu= Exit Enter = Yes 5.1.4 The instrument will show the phrase “Connect a 100 Ohm Standard Resistor and Press Enter” to indicate that a 100Ω must be connected to sensor1 (S1) terminals as Figure3. Users can exit the calibration by pressing key to go back to the main menu (*CALIBRATION MENU*). MENU 5.1.
AM8060 Precision Thermometer User’s Guide users can adjust the value by using and keys. The adjusted result will appear like the picture below: * 100 Ohm CALIBRATION 100R Rs = OHM 100.0038 Rt = 100.0038 Menu= Exit OHM <^v>=Adj 5.1.7 It is required to wait for 10 seconds for the data to be stable. Each second is shown with a blinking dot at the top left hand corner of the display. Once this is completed, the next step involves saving the calibrated data.
AM8060 Precision Thermometer User’s Guide ensure the measurement/calibration switch at the rear panel is moved to the “CAL” side (right side), as shown in Figure 3. 5.2.2 Choose the 25 Ohm CALIBRATION under main menu (*CALIBRATION MENU*) by touching or key to move the “>” to the “25 Ohm CALIBRATION” line: * CALIBRATION MENU ------------------------------------------100 Ohm CALIBRATION > 25 Ohm CALIBRATION Enter = Yes 5.2.3 Touch key to start the program of 25 Ohm CALIBRATION.
AM8060 Precision Thermometer User’s Guide resistance is calculated, and the following message will appear: * 25 Ohm CALIBRATION 25R Rs = OHM 25.9977 Rt =25.0000 Menu= Exit OHM Enter = Yes 5.2.6 The value on the third line is the parameter to be adjusted and this value must match the standard resistance of the 25Ω resistor. For example, the above figure shows the current value as 25.9977, but the standard resistor’s value is 24.9977.
AM8060 Precision Thermometer User’s Guide touch the key, and the third line of data will blink to indicate the option to save. MENU 5.2.8 To save this calibration, press and hold the key and then press the key. This will save the calibration data to the instrument, and the program will go back to the main menu (*CALIBRATION MENU*);If users DO NOT want to save the data, press the key will bring the program back to the main menu ( *CALIBRATION MENU*).

AM8060 Precision Thermometer User’s Guide 6 Wireless Data Acquisition The AM8060 precision thermometer can transmit temperature data through a wireless transmission module. Free software for this feature is included with the AM8060. To transmit data wirelessly, users will need the followings: AM8060-W, precision thermometer with embedded wireless function. Wireless Transceiver . USB cable with length of 2m to 5m. Computer with USB interface and Windows operating system.
AM8060 Precision Thermometer User’s Guide 2) The computer and Wireless Transceiver must be within 50m (indoors) or 80m (outdoors) from the AM8060. The computer must be powered on. 3) Connect the Wireless Transceiver to the computer with a USB cable. Place it at a high spot for best performance. The system setup is shown in Figure4. 4) After connecting the Wireless Transceiver to the computer, the user will be required to install USB drivers unless the PC is running on Windows7 operating system.
AM8060 Precision Thermometer User’s Guide 7) “The Base Status” and “Remote” wil display “Wireless Base RF OK” and “Wireless Remote OK” to confirm the wireless connection. The value after “ADDR” shows the wireless address of the AM8060. The value after “RSSI” is the wireless signal strength, which will not display until the user clicks on “Start”. The RSSI should be greater than -99dBm. Otherwise, the wireless signal is too weak and the link is not stable.
AM8060 Precision Thermometer User’s Guide CDrN_2xAir_Reader should also show the signal strength, as seen below: 9) The wireless data acquisition can be halted by clicking on “Stop”, or by clicking on “Exit” to quit the program. The default setting for a sampling period is 1 second. The data acquisition process can be restarted by clicking on “Start”. 10) CDrN_2xAir_Reader can also save the captured data to a file, entitled “Air_data.txt”. The data sampling rate can also be adjusted.
AM8060 Precision Thermometer User’s Guide when the sampling is stopped. The data sampling can be restarted after the modification. Users can save data by clicking on “Start”,and then clicking on the “REC” button. The captured temperature data is saved into “Air_data.txt”, and the phrase “Recording…” will appear under “Data Saving” to indicate the recording process has begun. To stop data saving, clicking on “END” or “Stop” will cease the temperature data capture.

AM8060 Precision Thermometer User’s Guide 7 Using a Flash Drive(U disk)for Data Acquisition The flash drive recording start/stop key saving data to the USB flash drive. REC can be used for There is a USB port on the rear panel of the AM8060 which can be used to store the measured temperature data to a flash drive. Any flash drive with size lower than 4 gigabytes can be connected to the “UDrive” connector at the rear panel.
AM8060 Precision Thermometer User’s Guide above the REC key will be turned on. This is to inform the user that the temperature data is being written to the flash drive. The saved file name is U2DATA.txt. 5) If users want to stop the data saving, just press REC key on the front panel. AM8060 will produce a short beep and the LED above REC key will be turned off to indicate the process has been halted. The following list is an example of data saved in the U2DATA.txt file on a flash drive.
AM8060 Precision Thermometer User’s Guide While using the flash drive, the data saving period can be adjusted with the front panel. The default saving period is 1.21 seconds, and it can be set as a multiple of this value, with the multiple ranging between 1 and 65,535. The instructions for this are as follows: A. When AM8060 is in a normal working state, press key and then hold key for 3 seconds. The AM8060 will display the main menu as below: MENU B.
AM8060 Precision Thermometer User’s Guide It should be noted that this operation is a two-key operation. Don’t release the key before touching key. D. Press key or key to adjust the “N” value (which must be equal or greater than 1). E. After the adjustment, press key. The new adjusted value will blink to indicate whether the user wishes to save this new N value. For example,the above picture shows the new N value as 9, which means the AM8060 will save data to the file every 9x1.21 seconds.
AM8060 Precision Thermometer User’s Guide F. After the adjustment, press multiple times until the AM8060 returns to its normal working state. MENU Note: The parameter adjustments should only be performed while the flash drive is not in the data saving process.
