Normal Volts And Aux Volts Phase; Volts And Aux Current Phase - Fluke 5500A Service Manual

3-17. NORMAL Volts and AUX Volts Phase

NORMAL volts and AUX volts phase calibration is only accessible by remote
command. See "Remote Commands for 5500A Calibration," later in this chapter. In
remote, you can jump to NORMAL volts and AUX volts phase calibration by sending
the command:
CAL_START FACTORY,PHASE
Measure with a phase meter of suitable accuracy as shown in Figure 3-7. Enter into the
5500A the measured values when prompted.
The 5500A outputs the voltages shown in Table 3-10. The 5500A is automatically set to
LOs open.

3-18. Volts and AUX Current Phase

The 5500A outputs the voltages and currents shown in Figure 3-8. The 5500A is
automatically set to LOs open. You need to externally connect the NORMAL LO and
AUX LO. To measure the phase, connect a 0.1 Ω, 1.0 W low-inductive shunt directly
across the AUX terminals and sense the voltage there with a phase meter of suitable
accuracy. Table 3-11 shows the steps in this procedure. In remote, you can jump to
NORMAL volts and AUX current phase calibration by sending the command:
