4. On the UUT, select the dc voltage function and the 2 volt range. Turn
R6 fully clockwise (CW), and turn R5 fully counterclockwise (CCW).
5. Program the DMM Calibrator for an input of 1.9000V dc. Adjust R5 for
a display reading slightly greater than 1.9000. Adjust R6 for a display
reading between 1.8999 and 1.9001.
6. On the UUT, select the 200 mV range (dc voltage functions).
7. Program the DMM Calibrator for an input of 190.00 mV dc. Adjust R8
for a display reading between 189.99 and 190.01.
8. On the UUT, select the ac voltage function and the 200 mV range. Turn
R18 fully CW, and turn R15 fully CCW.
9. Program the DMM Calibrator for an input of 100.00 mV ac at 200 Hz.
Adjust R15 for a display reading slightly greater than 100.00. Adjust
R18 for a display reading between 99.95 and 100.05.
10. On the UUT, select the 200V range (ac voltage function). Program the
DMM Calibrator for an input of 100.00V ac at 10 kHz. Adjust C3 until
the display reading is between 99.95 and 100.05.
11. On the UUT, select the 2V range (ac voltage function). Program the
DMM Calibrator for an input of 1.0000V ac at 10 kHz. Adjust C7 until
the display reading is between .9985 and 1.0015.
12. Repeat steps 10 and 11 before proceeding to step 13.
13. On the UUT, select the 20 V range (ac voltage function). Program the
DMM Calibrator for an input of 10.000V ac at 10 kHz. Adjust C8 until
the display reading is between 9.990 and 10.010.
14. On the UUT, select the 200 mV range (ac voltage function) and press
the Hz button under the display. The Hz indicator should appear on the
display.
15. Program the DMM Calibrator for an input of 50 mV ac at 100 kHz.
Adjust R9 for a stable reading between 99.95 and 100.05.
16. Decrease the signal input by 5 mV and repeat step 15. If the signal level
is no longer sufficient to obtain the required reading, leave R9 at the
most stable and accurate setting.
