Calibration
2-19
10. Set the calibrator output to 200V AC at 30kHz, then
press ENTER. The Model 2002 will display the
following:
Low-Level Cal - Step 4 of 13
11. The unit will then prompt for the next calibration signal:
Connect 1.5V @ 1kHz
12. Set the calibrator for 1.5V AC at a frequency of 1kHz.
The Model 2002 will display the following:
Low-Level Cal - Step 5 of 13
13. The unit will display the following:
Connect 200mV @ 1kHz
14. Program the calibrator to output 200mV at a frequency
of 1kHz, then press ENTER. The Model 2002 will then
display the following:
Low-Level Cal - Step 6 of 13
15. When finished with this step, the unit will display the
following:
Connect 5mV @ 100kHz
16. Set the calibrator to output 5mV at a frequency of
100kHz, then press ENTER. The Model 2002 will then
display the following while calibrating:
Low-Level Cal - Step 7 of 13
17. Following step 7, the instrument will display the follow-
ing message to prompt for the next calibration signal:
Connect 0.5mV @ 1kHz
18. Program the calibrator to output 0.5mV at 1kHz, then
press ENTER. The unit will display the following in-
progress message:
Low-Level Cal - Step 8 of 13
19. Next, the unit will prompt for the next calibration signal:
Connect 100 VDC
NOTE
The accuracy of the 100V source is espe-
cially critical. It may be necessary to ad-
just the calibrator output slightly to
achieve exactly 100V.
20. Set the calibrator to output +100V DC, then press the
ENTER key. The Model 2002 will advise you that the
current step is in progress:
Low-Level Cal - Step 9 of 13
21. After this step has been completed, the unit will display
the following:
Connect -20 VDC
NOTE
The accuracy of the -20V source is espe-
cially critical. It may be necessary to
adjust the calibrator output slightly to
achieve exactly -20V.
22. Set the calibrator for an output voltage of -20V DC, then
press ENTER. The Model 2002 will display the follow-
ing message:
Low-Level Cal - Step 10 of 13
23. The Model 2002 will then prompt for the next calibra-
tion signal:
Short Rear Inputs
24. Connect the Model 8610 to the rear INPUT jacks, mak-
ing sure that the terminals are in the correct position.
Select the rear inputs with the FRONT/REAR switch,
and allow at least three minutes for thermal equillib-
rium. Press ENTER to continue. The Model 2002 will
display the following:
Low-Level Cal - Step 11 of 13
25. After completing step 11, the unit will display the
following:
Connect 20mA @ 1kHz
26. Connect the calibrator to the AMPS and INPUT LO
jacks.(See Figure 2-3.) Press the FRONT/REAR switch
to select the front inputs.
27. Set the calibrator output to 20mA AC at a frequency of
1kHz, then press the ENTER key. The Model 2002 will
display the following while calibrating:
Low-Level Cal - Step 12 of 13
28. The unit will then prompt for the final calibration signal:
Connect 2 V at 1 Hz
29. Put the calibrator in standby, then disconnect it from the
Model 2002 INPUT and AMPS jacks; connect the syn-
thesizer to INPUT HI and LO, as shown in Figure 2-5.
Set synthesizer modes as follows:
FCTN: sine
FREQ: 1Hz
AMPTD: 2Vrms
MODE: CONT
OFFSET: 0V
