b. Connect the 100 kilohm ± 0.01% resistor in the
position as shown.
c. Set the Multimeter function to DCA (
A) and
range to 200 fxA. Adjust the power supply output for a
differential voltmeter reading of 1.000 V. The Multimeter
should indicate 99.98 to 100.02 /rA.
d. Check all the Multimeter ranges, using the values of
and differential voltmeter readings shown in Table 5-3.
Ihe Multimeter display should indicate within the limits
provided.
5-10. Ohms Accuracy Test.
5-11. A precision resistive decade box will be required for
this test. It should be calibrated and have a known accuracy
of .005%.
a. Connect the equipment as shown in Figure 5-2.

the indicated resistances. The Multimeter display should
indicate within the limits provided.

a. Set the Multimeter function to ACV (~V). Cormect
the AC Calibrator between the Vf2 terminal and COM
terminal. Be sure to connect the Calibrator sense leads.
b. Check the voltage ranges listed in Table 5-5 at each
frequency listed. The Multimeter should indicate within the
limits provided.
5-14. AC Ammeter Accuracy Test
5-15. An AC Calibrator, a 3450B Digital Voltmeter and
discrete resistors (Ra) indicated in Table 5-6 are required
for this test. Even though lesser accurate resistance values
are required for this test, it is expedient to use the resistors
specified in Table 5-1.
a. Set the Multimeter function to ACA (~ A) and range
to 200 /lA. Connect the equipment as shown in Figure 5-3
using a discrete resistor for R^. (To select R^. note the
