Calibration
Model 2701 Service Manual
Measuring function generator signal amplitude
The 3Hz function generator signal amplitude must be accurately measured using the digital
multimeter listed in
Table 2-13
. Proceed as follows:
1.
Connect the function generator output to the digital multimeter INPUT jacks. (See
Figure 2-5
for typical connections.)
2.
Turn on the function generator and multimeter, allow a two-hour warm-up period
before measuring.
3.
Set the function generator to output a 1V RMS sine wave at 3Hz. Measure and record
the signal amplitude.
Front panel manufacturing calibration
1.
Install the shorted Model 7797 calibration board (see “Calibration card preparation”
earlier in this section) in scanner card Slot 1 and select the rear inputs with the INPUTS
switch. Allow three minutes for thermal equilibrium.
2.
Press and hold the OPEN key while turning on the power.
3.
Press SHIFT then TEST, then display CALIB: TEST with the up or down range key.
Press ENTER, select RUN, then enter the appropriate calibration code (default:
002701).
4.
Select ALL at the CAL:RUN prompt.
5.
Press ENTER to perform the first manufacturing calibration step.
6.
Perform the entire front panel comprehensive calibration procedure discussed earlier in
this section. (See “Comprehensive calibration” earlier in this section.)
7.
Connect the function generator to the Model 2701 front panel INPUT jacks as shown in
Figure 2-5
. Select the front input jacks with the INPUTS switch.
