required test values by rotating the LOAD CONTROL
the inverter.
4-12. Obtain voltage and current values of individ-
ual circuits and record as follows:
a. Three-phase inverter:
1. Set A.C. PHASE switch (18) to 30.
2. Selectively rotate A.C. PHASE selector (19)
indicator through engraved ranges 1, 2, and 3 (phase
recording).
3. Observe meter indications at each phase
point, and record.
b. Single-phase inverter:
1. Set A.C. PHASE switch (18) to 1.
2. Set A.C. Phase Selector (19) to Neutral
Position.
3. Observe Meter Indications and Record.
4-13. AFTERTESTING PROCEDURE.
4-14. Test being completed, rotate the LOAD CON-
counterclockwise to 0%, and position toggle switches
LOAD (13), D.C. PWR (12A), and LIVE CIRCUIT (16)
to OFF.
4-15. Remove attached cable assembly and store
all cable assemblies in storage compartment. Cover
tester when not in use to protect equipment.
