b. Adjustments (fig. 1)
(1) Adjust R56 for minimum indication (less than 1 mV) on multimeter (R).
(2) Adjust R9 for minimum indication (less than 1 mV) on multimeter (R).
(3) Adjust R32 for minimum indication (less than 1 mV) on multimeter (R).
(4) Adjust R33 for minimum indication (less than 1 mV) on multimeter (R).
12. Ratio
a. Performance Check
(1) Position switches as listed in (a) through (h) below:
FUNCTION to FREQ A (FREQ).
(a)
MULTIPLIER (TIME BASE/MULTIPLIER) to 1 ms.
(b)
SLOPE A (SLOPE) to + (plus).
(c)
AC/DC to AC.
(d)
ATTEN to X1.
(e)
CHK-SEP-COM (CHK-NORM) to SEP (NORM).
(f)
OSC (located on rear panel) to EXT.
(g)
LEVEL A (LEVEL) to PRESET.
(h)
(2) Connect function generator to OSC jack, using 50
feedthrough termination.
(3) Connect calibrator to INPUT A (CHANNEL A) jack.
(4) Adjust function generator for 10 MHz at 1 V rms, and calibrator for 100 kHz at
100 mV rms. TI will indicate a ratio of 0.100 (disregarding units digit and decimal point).
b. Adjustments. No adjustments can be made.
13. DVM Accuracy and Tracking (Model 5326B)
a. Performance Check
(1) Position controls as listed in (a) through (e) below:
FAST/NORM/HOLD switch to NORM.
(a)
FUNCTION switch to DVM.
(b)
TIME BASE switch to 1s.
(c)
RANGE switch to 10 V.
(d)
OSC (rear panel) to INT.
(e)
(2) Connect a lead between DVM INPUT terminals.
If indication on TI is not
0.0000 V ( 1 count), perform b (1) below.
(3) Remove lead from DVM INPUT terminals.
(4) Connect calibrator to DVM INPUT terminals.
(5) Adjust calibrator output for a 1.0000 V indication on TI. If calibrator does not
indicate between 0.9975 and 1.0025 V, perform b (2) through (5) below.
