(a) Rx channel [XX] compared to Rs channel [XX] at [per table 4 Range Extender
(b) [x Ratio in Low] Ohms with the reference as [Rs]. This Reversal rate is  s
[fixed with auto reversal rate set to disabled] at a threshold of [0.00] ppm.
(c) Stop the test if a target deviation of [0.0] ppm over a [0.0] sample window, or
at the  sample limit.
(d) Run the software to measure the resistor; then, from the main screen select
VIEW, TEST OVERVIEW.
(e) From the TEST OVERVIEW screen select FILE, OPEN, and locate the folder
named for the test.
(f) Find the saved run data. Since the first 50 data points include settling
effects, cut them off and use the mean of the last 13 data points only.
(g) Select FILE, DATA MANAGER.
(h) Assuming 63 data points total with the first point being number 0, select
START AT  and GO TO .
(j) Record the [test mean], the average value of the last 13 data points.
(k) The [Standard Deviation ppm] is not used; however, if it is bigger than the
tolerance for the particular test, it is an indicator that the measurement needs to be
(3) For each test point in table 5, connect each characterized shunt to the TI (fig. 2,
connection 2) and measure with the appropriate range. TI must indicate the characterized
value within the limits. If not, perform c below.
(1) Set TI rotary switch to SET-UP. Set will appear in the display.
(2) Press > "Right Arrow" to display "00000". Enter the factory password (09456):
Press > "Right Arrow "to display 00000. With the ^ "Up Arrow" enter the first number of
the password 0. Press > "Right Arrow" and enter the second number 9. Repeat until all
password numbers are entered.
(3) When all password numbers entered, press > "Right Arrow" and CPt A will appear
on the display.
(4) Press > "Right Arrow" to display "Pt00r". Press ^ "Up Arrow" to select range to
be adjusted (250 m will display 250n; 250 will display 250r). On some models press the
^ "Up Arrow" and Adj will appear in the display. Press > to select the range to be adjusted.
(5) Connect the correct resistance standard for the range being calibrated.
