Supplying Power through
Measurement Lines
If AC power cannot be supplied from an outlet, you can use a power
supply adapter (98031) to supply power through voltage probes.
• If the probe and the measurement category of the main unit
are mismatched, the lower measurement category takes
precedence. Be sure to check that the measurement voltage
and rating are matched.
• Never connect voltage probes that are not necessary for the
measurement that you are taking.
• Do not connect to the measurement line when the probe is not
connected to the main unit.
• Never remove the probe from the main unit connector while
measuring (power running from the measurement line).
• Be sure to connect to the secondary side of the circuit breaker.
The current capacity is large on the primary side and is
dangerous.
• Connect the probe after checking that the instrument is turned
off.
• Connect the main unit end of the cord first. Firmly insert the
probe up to the base.
• If the probe cracks or the metal parts become exposed, stop
using it immediately.
