(b) MEASURE MODE (if necessary) to select TRIGGERED.
(c) Press 1 6 9 3 = SHIFT OPEN (GO indicator will light with "0" in the left
and right displays).
(d) Keep hands and objects at least 4 inches away from remote test fixture, then
press START button. (GO indicator extinguishes and lights again when complete).
(10) Remove calibration resistor labeled OPEN from the remote test fixture.
(11) Place calibration resistor labeled SHORT in the remote test fixture.
(12) Perform TI short circuit compensation by completing (a) through (d) below.
(a) FUNCTION (if necessary) to select MEASURE.
(b) MEASURE MODE key (if necessary) to select TRIGGERED.
(c) Press 1 6 9 3 = SHIFT SHORT. (GO indicator will light with "5" in the left
and right displays).
(d) Keep hands and objects at least 4 inches away from remote test fixture, then
press START button. (GO indicator extinguishes and lights again when complete).
(13) Remove calibration resistor labeled SHORT from the test fixture.
(14) Place first calibration resistor listed in table 6 in the remote test fixture.
(15) Set TI as listed in (a) through (g) below.
(a) FUNCTION (if necessary) to select ENTER.
(b) DISPLAY (if necessary) to select VALUE.
(c) MEASURE RATE (if necessary) to select SLOW.
(d) MEASURE MODE (if necessary) to select CONT.
(e) EQUIVALENT CIRCUIT (if necessary) to select SERIES.
(f) R/Q (if necessary) R in upper left must be lit.
(g) SHIFT DQ in PPM (if necessary) PPM in lower right display must be lit.
NOTE
In step (16) below, the value of n must be entered in ohms
when the calibration resistor is either 24.9 Ω or 374 Ω (i.e.
24.9011 or 374.007). Entry must be made in kΩ when the
calibration resistor is either 5.97 kΩ or 95.3 kΩ (i.e. 5.96967 or
95.2932). In all cases, enter 6 digits of resolution though only 5
digits will be displayed.
(16) Enter new calibration coefficients by completing (a) through (h) below.
(a) 4 = SHIFT SPECIAL 1 (to enter adjustment mode for range 4).
(b) n = SHIFT NOM VAL (where n = present measured value of calibration
resistor recorded in 7 b (7) above with 6 digits of resolution, i.e. 24.9011).
(c) Q = SHIFT BIN NO 0 0 (where Q = value of Q, in ppm, permanently
assigned and indicated on the calibration resistor, i.e. 10).
