Switch System Reference Manual
Press in and hold the OPEN key while turning on the power.
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: 002790).
Select ALL at the CAL:RUN prompt.
Press ENTER to perform the first manufacturing calibration step.
Perform the entire front panel comprehensive calibration procedure. See
"Comprehensive
calibration" earlier in this section.
Connect the function generator to the Model 2790 front panel INPUT jacks as
shown in
Figure
17-6. Select the front input jacks with the INPUTS switch.
After the last AC current calibration step, the instrument will prompt you to enter
3Hz at 1V RMS and 1kHz with the following prompts:
•
Low-frequency cal: Set the function generator to output a 1V RMS, 3Hz sine
wave. Use the left and right arrow keys and the range keys to adjust the display
to agree with the generator amplitude you measured previously, then press
ENTER.
•
Frequency cal: Set the function generator to output a 1V RMS, 1kHz sine
wave. Enter 1.000000kHz at the prompt, then press ENTER.
Set the calibration dates, then save calibration to complete the process.
Install the shorted calibration extender board (see
earlier in this section) in scanner card Slot 1 and select the rear inputs with the
INPUTS switch. Allow three minutes for thermal equilibrium.
Press in and hold the OPEN key while turning on the power.
Enable calibration by sending the :CODE command. For example, the default com-
mand is:
:CAL:PROT:CODE 'KI002790'
Initiate calibration by sending the following command:
:CAL:PROT:INIT
Calibrate step 0 with the following command:
:CAL:PROT:DC:STEP0
Perform the entire remote comprehensive calibration procedure. See
calibration" earlier in this section.
Connect the function generator to the Model 2790 INPUT jacks as shown in
Figure
17-6. Select the front input jacks with the INPUTS switch.
Set the generator to output a 1V RMS, 3Hz sine wave, then send the following
command:
:CAL:PROT:AC:STEP14 <Cal_voltage>
Here <Cal_voltage> is the actual 3Hz generator signal amplitude you measured
previously.
