Keithley 2700 Service Manual

Calibration 2-21
Remote manufacturing calibration
1. Install the shorted calibration extender board (see “Extender board 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 in and hold the OPEN key while turning on the power.
3. Enable calibration by sending the :CODE command. For example, the default com-
mand is:
:CAL:PROT:CODE 'KI002700'
4. Initiate calibration by sending the following command:
:CAL:PROT:INIT
5. Calibrate step 0 with the following command:
:CAL:PROT:DC:STEP0
6. Perform the entire remote comprehensive calibration procedure discussed earlier in this
section. (See “Comprehensive calibration” earlier in this section.)
7. Connect the function generator to the Model 2700 INPUT jacks as shown in Figure 2-5.
Select the front input jacks with the INPUTS switch.
8. Set the generator to output a 1V RMS, 3Hz sine wave, then send the following com-
mand:
:CAL:PROT:AC:STEP14 <Cal_voltage>
Here <Cal_voltage> is the actual 3Hz generator signal amplitude you measured
previously.
9. Set the generator to output a 1V RMS, 1kHz sine wave, then send the following
command:
:CAL:PROT:AC:STEP15 1E3
10. Send the following commands to set calibration dates, save calibration, and lock out
calibration:
:CAL:PROT:DATE <year>, <month>, <day>
:CAL:PROT:NDUE <year>, <month>, <day>
:CAL:PROT:SAVE
:CAL:PROT:LOCK
