Frequency Test 4-11.
Rotate the GMM selector to , and check that the ‘Trigger’ selection is set to
‘Single’. To change to ‘Single’, press
t
(Next Item) to highlight the appropriate
selection line; then press
u
or
v
to make the selection. Complete the change by
pressing
x
(Save Set Up).
Rotate the GMM selector to AC Volts ( ). If necessary, press
v
to select (highlight)
‘Average’. Press

.
Connect the GMM and the PM5139 in Configuration 7 (Figure 4-5.) Then perform the
steps called for in Table 4-10. Before proceeding to the next test, place the PM5139 in
Standby.
