Measure the AUX output using a precision AC Voltmeter. Enter into the 5500A the
measured values of each step listed in Table 3-7 when prompted to do so.
Table 3-7. AUX AC Volts Calibration Steps
Step NORMAL Output AUX output Frequency
1 1.1 V 300 mV 100 Hz
2 1.1 V 300 mV 5 kHz
3 1.1 V 300 mV 10 kHz
4 1.1 V 3 V 100 Hz
5 1.1 V 3 V 5 kHz
6 1.1 V 3 V 10 kHz
7 1.1 V 3 V 9.99 Hz
3-13. Resistance
Use a precision DMM to measure the resistance output. Figure 3-3 shows the four-wire
connections. Enter into the 5500A the measured values of each step listed in Table 3-8
when prompted to do so.
