3. Verify that the amplitude is within 2% of the nominal value. See Table 2-12 below
for the acceptable limits for each amplitude.
4. Repeat steps 2 and 3 for 120 Hz, 1 kHz, 10 kHz, and 100 kHz (Calbytes 1, 2, 3
and 4) at this amplitude (0.10 V). Note that, for each amplitude, the calbyte num-
bers are in order of ascending frequency.
5. Repeat steps 2 to 4 for each amplitude in the table. At each amplitude, repeat the
measurement for each frequency, starting with 100 Hz and increasing to 100 Hz.

Frequency Calibration
This procedure measures the accuracy of the 9216A clock. The exact clock frequency is
used in calculating capacitance and inductance values. The clock correction factor is
stored in parts per million (ppm).
1. Set the 9216A to its default conditions by pressing the keys RCL 0 ENTER. Set
the unit to constant voltage mode at 1 kHz, and remove any part from the fixture.
2. Install the BNC adapter to the fixture. Connect the IH lead to the frequency coun-
ter.
3. Determine the new calbyte by the formula, Calibyte (frequency 1000.000)
1000.
4. To adjust the clock calbyte, press the CAL key until "Std cAL" appears on the
display. Press ENTER once to get into this menu structure, and then press CAL
