you may print a report for each of the probes calibrated using the PRINT RE-
PORT function.
It should be noted that the particular values for coefficients the 1575/1590 cal-
culates are very sensitive to slight variations in the temperatures and resistances
used. You may obtain different values for the coefficients each time you cali-
brate a probe even if the calibration is correct and accurate. The 1575/1590
may also produce coefficients that differ slightly from values calculated using
other software because of differences in mathematical precision, matrix solu-
tion approaches, and recursion methods. You may test the validity of the calcu-
lated coefficients using the CONV TEST function (see Section 7.4.4.5). You
should also compare measurements with the probe to those of a known accurate
SPRT to verify that it’s properly calibrated.
7.4.4.2.10 Print Report
The PRINT REPORT soft-key can be used to print a calibration report for any
of the probes that were calibrated. The report will show the probe serial num-
ber, the date, the current that was used, and the coefficients that were produced.
The table can also include the measured resistance and temperature data and a
resistance-temperature table. The report can be printed from the printer port,
serial interface, IEEE-488 interface, or written to disk.
The first window that appears allows you to select the probe and output port for
the report. You may use the
LR
buttons to select the probe. Only the probes
assigned channels in SETUP can be selected. Press Enter after changing the
probe number.
For the output port, you may select among the printer parallel port, serial port,
IEEE-488 port, or disk. Printing to disk may be useful if you want to customize
the report using a word processor. When printing to disk, the filename of the re-
port will be PROBEn.RPT where n is the probe number. If you print the report
from the serial or IEEE-488 port, you should first check that the interface pa-
rameters (baud rate, address, etc.) are set correctly using the SERIAL or
IEEE488 soft-keys in the SYSTEM - COMM MENU. Press Enter after chang-
ing the port.
If the parameters do not need to be changed, you may simply press the NEXT
soft-key to go to the next screen. You may also press the RETURN soft-key
from this screen to return to the menu after printing the reports.
The next window that appears asks whether or not you want to include the mea-
sured data with the report and allows you to select the units for this data. If the
parameters do not need to be changed, you may simply press the NEXT
soft-key to go to the next screen.
The next window asks whether or not you want to include the resistance-tem-
perature table with the report. You can also specify the units to use in the table,
the minimum and maximum temperatures, and the temperature interval. If the
parameters do not need to be changed, you may simply press the NEXT
soft-key to go to the next screen.
