Keithley 2010 Service Manual

Verifying frequency
Follow the steps below to verify the Model 2010 frequency function.
1. Connect the frequency synthesizer to the Model 2010 INPUT jacks. See Figure 1-7.
2. Set the synthesizer to output a 1kHz, 1V RMS sine wave.
3. Select the Model 2010 frequency function by pressing the FREQ key.
4. Verify that the Model 2010 frequency reading is between 0.99992kHz and 1.00008kHz.
Verifying ratio
CAUTION When verifying ratio or using sense volts, the SENSE LO terminal must be
referenced to INPUT LO. Exceeding 350V DC from SENSE HI to SENSE
LO will cause instrument damage.
1. Connect SENSE HI to INPUT HI, and connect SENSE LO to INPUT LO.
2. Connect the DC calibrator output HI and LO terminals to the Model 2010 HI and LO
terminals respectively, as shown in Figure 1-8.
3. Select the Model 2010 DCV function, and select the 1V range.
4. Set the DC calibrator output to +1.000000V DC, and turn on its output.
5. Press SHIFT then RATIO, then select and enable both RATIO:ON and SENSEIN:ON.
6. Verify that the ratio reading is between 0.9999460 and 1.0000540.
