Line Survey
Line survey allows the user to perform an amperage
draw and display those values on the main screen.

press OK .
You will be taken to the Test Menu .
2. Navigate to
4. Line Surv
and press
OK
.
3. Press OK when you are asked Activate Line
Survey?
You will observe the
vL
and
vG
values on the
display.
Note:
VL indicates voltage on line and normally ranges
between 34 - 37 V. VG indicates voltage to ground
and should be slightly negative. I
1
and I
2
indicate
currents in each of the lines in the two-wire path and
should be nearly identical. If these measurements
deviate much from each other this could indicate that
one of the two wires has a ground leakage. There may
be slight variations between values indicated on the
Line Surv screen and those that appear on the Test
Menu .
