4. Set the decade resistance box to each of the values shown in Table 1-8 , and verify that
the temperature readings are within the required limits.
Verifying frequency
Follow the steps below to verify the Model 2700 frequency function:
1. Connect the function generator to the Model 2700 INPUT jacks. (See Figure 1-7 .) Be
sure the INPUTS switch is in the FRONT position.
2. Set the function generator to output a 1kHz, 1V RMS sine wave.
3. Select the Model 2700 frequency function by pressing the FREQ key.
4. Verify that the Model 2700 frequency reading is between 999.9Hz and 1.0001kHz.
