Running a Continuous Voltage Test
To continuously monitor DC voltage on a pair, do the following:
1. Press A(
Contin. DCV).
The
Continuous DCV screen (Figure 4-5) is displayed.

Figure 4-5. Continuous Voltage Test Result Screen
Figure 4-5 shows a continuous DCV value for the T-R leg. The bar graph
plots real-time voltage variations against the reference (center) value of
the initial reading. Peak voltage excursions are recorded as half-tone
shaded portions of the bar, with excursions beyond the scale marked as
“Min” and “Max” values. The current reading is shown in large, solid
black numbers. Each scale mark on the bar graph corresponds to one unit
of measure (in this case, 1 volt) of the parameter.
2. To continuously test another leg, press B(
TG) or C(RG).
3. To re-center a reading that has drifted, press D(
Set New Reference).
4. To stop a continuous test, press K or M.
