15. Measure and note the voltage between TP14 and TP16 (typ. <1mV). Set
the display at 1 and press Enter . Measure the voltage once more and
adjust P5 until the difference between the voltages is 120mV

16. Repeat the previous instruction, only this time with the Sensitivity
switch set to position 5. Check that the voltage between TP14 and TP16
is 15mV

V. If necessary, adjust P5 and repeat operation 15.
17. Set the display at 2 and press Enter . Measure the resistance between
TP7 and TP10 with the multimeter. Adjust P1 until the voltage is half
the reference voltage between TP10 and TP9 (nom. -0.62v)
±
lmV.
18. Measure the voltage between TP6 and TP10 with the multimeter. Adjust
P2 until the voltage is half the reference current between TP10 and TP9
(nom. 0.62v) +lmV.
19. Measure and note the voltage between LL(+) and RA(-) (typ. <
100 ) V). Set the display at 3 and press Enter . Measure the voltage once
more and adjust P4 until the difference between the voltages is 2mV

V. Measure the voltages between the outputs and check that they
are within the limits in the following table:
Connectors Low limit Nom. Value High limit
RL - RA 1.20 mV 1.35 mV 1.50 mV
RL-LA 2.40mV 2.65mV 2.90mV
RL-LL 3.00 mV 3.35 mV 3.70 mV
RL-V1 2.70 mV 3.02 mV 3.30 mV
RL-V2 3.30 mV 3.72 mV 4.10 mV
RL-V3 4.00 mV 4.49 mV 5.00 mV
RL-V4 4.50 mV 5.06 mV 5.60 mV
RL-V5 4.00 mV 4.49 mV 5.00 mV
RL-V6 3.30 mV 3.72 mV 4.10 mV
20. Set the display at 4. Set the Base-ohms switch to 500 and the Lead
switch to II. Measure the resistance between LL and RA. Move between
test functions 4 and 5 on the display (remember to press
Enter ), and ad-
just P3 until the difference is 3 ohms
±
0.03 ohms.
