a. Performance Check
(1) Connect equipment as shown in figure 1.
(2) Position controls as indicated in (a) through (d) below:
(a) METER READING CURRENT pushbutton pressed.
(b) MODE MA and 1-10 pushbuttons pressed.
(c) Decade dials to indicate .10000000 (first decade to 10).
(d) POWER OPR pushbutton pressed.
(3) Measure voltage across dc current shunt.
If multimeter does not indicate
between -0.100060 and -0.099940 perform b (1) below.
(4) Press POWER STDBY/RESET pushbutton.
(5) Repeat technique of (2) through (4) above at TI settings using shunt settings
listed in table 5. Multimeter will indicate within limits specified.
