Keithley 2010 Service Manual

Remote manufacturing calibration (firmware A13 and lower)
1. Connect the low-thermal short to the rear panel input jacks, 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 command
is:
:CAL:PROT:CODE 'KI002010'
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 synthesizer to the Model 2010 INPUT jacks as shown in Figure 2-7. Select
the front input jacks with the INPUTS switch.
8. Set the synthesizer 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 synthesizer signal amplitude you measured
previously.
9. Set the synthesizer 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
Calibration 2-25
