c. Adjust dc power supply to provide system voltmeter reading of 1.50 v.
e. Model 410C should read | approximately |
150 ma. This will verify a | Rin o f a p p r o x i - |
mately 0.3 ohms, where
R410C = E total - R X I 4 1 0 C
I410C
f. Set Model 410C RANGE to 1.5 µa.
g. Replace Rx with a 9 K ohm ±1% resistor Part No.
h.Adjust dc power supply to provide system voltmeter reading of 13.5 mv.
j.Model 410C should read approximately 1.5
µa. This will verify R in of 9 K on 1.5 µa range.
5-16. 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.
d. Connect COM and DCA OHMS cables across 10 ohm resistor.
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.
