7.9.8 Prb Type This function specifies the type of probe and its characterization. It allows the instrument to use the appropriate algorithm to calculate temperature from the measured resistance of the probe. The functions that follow the probe conver- sion function for setting probe characterization coefficients depend on the se- lected probe type. - Page 43 1522 Handheld Thermometer Readout User’s Guide Coefficients R(.01) Consider the following examples. Example 1: A PRT was calibrated to ITS-90 and its calibration certificate states values for coefficients R(273.16K), a4, b4, a8, and b8. Set the instrument's coefficients to the certificate values as follows.

Communications Interface Remote communications allows an external device, such as a computer, to com- municate with the instrument to obtain measurement data and control its opera- tion. Communication is accomplished with various commands issued to the instrument through the RS-232 serial port. RS-232 Connection The three-conductor jack for the serial port is located on the top of the instru- ment near the probe connector. -
Page 49: Communication Command List
1522 Handheld Thermometer Readout User’s Guide The protocol for serial communications is 8 data bits, 1 stop bit, and no parity. Use no flow control.

Page 53: Calibration
Calibration The 1522 should be calibrated at regular intervals to ensure that it continues to measure with proper accuracy. Calibration should only be done by qualified, authorized personnel. Required Equipment The following items are required to test and calibrate the 1522: 0 four-wire resistor (short) 25 four-wire resistor, accurate within 20 ppm (±0.0005 ) - Page 54 1522 Handheld Thermometer Readout User’s Guide 4. Verify the accuracy at 0 , 4k , 10 k , 40 k , 100 k , and 500 k . 5. Set the meter calibration date to the present date (see Section 7.9.18).

Page 55: Maintenance
If the AC adapter becomes damaged, have it replaced immediately. Never disassemble the AC adapter or attempt to repair it. If the instrument is used in a manner not in accordance with the equip- ment design, the operation of the thermometer readout may be impaired or safety hazards may arise. -
Page 56: Troubleshooting
Troubleshooting In case you run into difficulty while operating the 1522, this section provides some suggestions that may help you solve the problem. Below are several situa- tions that may arise followed by possible causes of the problem and suggested actions you might take. -
Page 57: Downloading Autologged Data
The 1522 Handheld Thermometer readout stores up to 10,000 readings in its autolog memory. These readings can be downloaded to a computer using the RS-232 serial port. By default, the 1522 serial port operates at 2400 baud. However, when downloading autologged readings over the serial port or print- ing to a serial printer, the instrument temporarily changes its baud rate to 9600 baud to reduce the download time. -
Page 58: Troubleshooting
If you wish to abort the download process before it has completed, press 'CLR' on the front panel of the 1522. The 1522 sets its baud rate back to 2400 baud automatically. Reset the terminal program's baud rate to 2400 baud. -
