1. Set the 9216A to 1 kHz, 1 V and constant voltage. Set the scope to 1 V/div verti-

cal and 0.5 ms/div horizontal. Connect a 10 probe to the scope.

2. Place the tip of the probe into the "+" side of the fixture and connect the ground

clip to the center guard.

3. The scope should display a sine wave that occupies two divisions horizontally

and about 5.5 divisions peak to peak vertically (1.0 Vrms - 2.83 V peak to peak).

There should be no irregularities in the waveform.

4. Change the amplitude setting of the 9216A to 0.25 and 0.10 V in succession and

verify that the output is within 2% of nominal.

5. Set the amplitude back to 1.0 V. Change the 9216A and scope settings to verify

that the output at 100 Hz, 120 Hz, 10 kHz and 100 kHz is within 2% of nominal.

Resistance Measurement

This test verifies that the 9216A operates and is able to measure a component in each of

its ranges. The readings obtained should be within (tolerance of the component + toler-

ance of the 9216A).

1. Press the key sequence RCL 0 ENTER to put the unit in its default setup.

2. Perform open and short circuit calibrations for the fixture configuration to be used.

See Volume 1 for details on these null calibrations.

3. Set the unit to the R+Q measurement mode, series equivalent circuit, and 1 kHz

test frequency. Install the 24.9  resistor.

4. Verify that the meter reads the resistance correctly to within 0.15%. Verify that

Q is a small value, about +0.0001 or smaller. Install the 402  resistor. Verify

that the meter reads the resistance correctly to within 0.15%. Verify that Q is a

small value, about +0.0001 or smaller.

5. Change the equivalent circuit to parallel. Install the 6.34 k resistor. Verify that

the meter reads the resistance correctly to within 0.15%. Verify that Q is a small

value, about 0.0001 or smaller.

6. Install the 100 k resistor. Verify that the meter reads the resistance correctly to

within 0.15%. Verify that Q is a small value, about 0.0002 or smaller.

Capacitance Measurement

This test verifies that the 9216A is able to measure components at different frequen-

cies. The limits of the readings are the same as before:  (component tolerance + meter

tolerance).

1. If the fixture configuration has changed, perform open and short circuit calibration.

2. Set the 9216A to the C+D measurement mode, parallel equivalent circuit, and 1

kHz test frequency.

3. Install the 22 nF capacitor. Verify that the unit reads the capacitance correctly to

within 1.10%. Verify that D is below 0.0001.
