CP03x/CP03xA Current Probes
2
Do not overload; observe all ratings
.
To avoid electric shock or fire, do not connect the
current probe to any wire that carries voltages or currents that exceed the ratings of
the probe.
Connect and disconnect properly . Connect the probe to the measurement instrument
before connecting to the circuit/conductor being measured. Avoid damaging the cable
through excessive bending.
Never install or remove the probe on bare conductors which are energized . The
transformer core and shield are grounded but not insulated and may contact the
conductor when the locking lever is open.
Be careful not to damage the insulation surface when making measurements. Before
clamping to the conductor being measured, check that the insulation on the conductor
is undamaged, and take care not to damage the insulation when clamping the
conductor. Any damage to the insulation could cause an electric shock.
Use only indoors and within the operational environment listed. Do not use in wet or
explosive atmospheres.
Do not remove the probe's casing . Touching exposed connections may result in electric
shock.
Keep product surfaces clean and dry.
Comply with the maximum input current vs. frequency derating when measuring
current that includes a high frequency component. Using the probe at high frequencies
or in strong magnetic fields may cause the device to become abnormally hot, resulting
in fire, equipment damage or burns.
Do not operate with suspected failures . Before each use, inspect the probe and
accessories for any damage such as tears or other defects in the probe body, cable
jacket, accessories, etc. If any part is damaged, cease operation immediately and
sequester the probe from inadvertent use.
NOTE: Depending on the amplitude and frequency of the current being measured, the
sensor head may emit a resonant sound. This sound may also occur during
demagnetizing operation, but it does not represent a malfunction (device failure).
