ScopeMeter Test Tool Tutorial

8 - 5

MAKING LOW FREQUENCY VOLTAGE
MEASUREMENTS WITH THE METER

The ScopeMeter test tool can make RMS voltage
measurements on signals as low as 1 Hz. In this example,
you will practice making such a measurement.

Connection

Connect the red scope probe from INPUT A (meter high) to
TP1 (the test signal) on the Demo Board. Connect the
meter low to ground of the Demo Board using either the
COM banana input with a test lead or the ground lead of
the probe hook clip. Remove all other connections.

Making the Measurement

1. Reset the ScopeMeter test tool (

+

).

You should now see two unstable voltage readings, an
invalid Hz reading, and the waveform display. Also you
occasionally hear the ranging relays click. The autoranging
is the result of a low frequency signal being produced at
TP1. This can be examined by finding the minimum and
maximum levels of the signal. See following example.
