Replace Rx with a 9 K ohm ±1% resistor
Part No. 0730-0026).
h. Adjust dc power supply to provide system
voltmeter reading of 13.5 mv.

OHMMETER OPERATION.
a. A 10 ohm ±l% resistor Part No. 0727-
0335) and a 10M resistor Part No. 0730-
0168) will be required for this test.
b. Set Model 410C FUNCTION SELECTOR to
OHMS; RANGE to RX10.
c. Set pointer to using rear panel adjust-
ment (OHMS ADJ) if required.
h. If both of these ranges function properly, it
can be assumed that the remainder will also .
If meter does not function properly, refer to
Paragraph 5-31 for adjustment procedure.

d. Connect COM and DCA OHMS cables across
10 ohm resistor.
5-19. AMPLIFIER GAIN CHECK.
e. Meter should read 1 (±5%), indicating 10
ohms.
f. Reset Model 410C RANGE to RX10M. Re-
place 10 ohm resistor with 10 M ohm resistor.
g. Meter should read 1 (+5%), indicating 10 M
ohms.
