(4) Set calibrator for an initial 100 mA output and rotate calibrator knob below
EDIT FIELD pushbutton to adjust calibrator for a TI indication of 100 mA.
(5) Set calibrator to STANDBY.
(6) Position frequency counter controls as listed in (a) through (i) below:
(a)
FUNCTION to TIME A-B.
(b)
INPUT A slope to
(positive).
(negative).
(c)
INPUT B slope to
(d)
INPUT A 1X/10X to 1X.
(e)
INPUT B to COM A.
(f)
INPUT A AC/DC to DC.
(g)
INPUT A 50Ω/1MΩ to 50Ω.
(h)
INPUT B 50Ω/1MΩ to 50Ω.
(i)
MEASUREMENT TIME to 80 ns.
(7) Set calibrator to OPERATE and adjust frequency counter TRIGGER LEVEL
SET A to start count (approximately 2.5 V).
(8) Adjust frequency counter TRIGGER LEVEL SET B to stop count
(approximately 2.5 V).
(9) Repeat (7) and (8) above as necessary until frequency counter starts when
calibrator is in OPERATE, stops when calibrator is in STANDBY and A and B TRIG
indicator lights are blinking in unison when calibrator is in OPERATE. Leave calibrator
in STANDBY after establishing trigger level.
(10) Set mASEC mA switch to mASEC and READ mASEC-ERASE switch to
ERASE.
NOTE
In the following steps do not leave calibrator in OPERATE for
more than 1 second as monitored on frequency counter.
(11) Momentarily set calibrator to OPERATE. TI will indicate 00.0 0.1 mASEC; if
not perform b (1) through (4) below.
(12) Set READ mASEC-ERASE switch to READ mASEC.
(13) Momentarily set calibrator to OPERATE. If TI does not indicate same reading
in mASEC as frequency counter indicates in time, 2 digits, perform b (5) through
(16) below.
(14) Press TI RANGE 2000MA pushbutton and repeat steps 12 a (3), (4), (5), (9),
and (10) above.
(15) Momentarily set calibrator to OPERATE. TI will indicate 000 1 mASEC.
(16) Set READ mASEC-ERASE switch to READ mASEC.
(17) Momentarily set calibrator to OPERATE. TI will indicate the same reading in
mA as frequency counter indicates in time, 2 digits.
b. Adjustments
(1) Disconnect TI from equipment setup.
