Important safety information
Provide proper
ventilation. TCPA300/400 only: Refer to the installation
instructions in the manual for details on installing the product so it has proper
ventilation.
Slots and openings are provided for ventilation and should never be covered or
otherwise obstructed. Do not push objects into any of the openings.
Probes and test leads
Before conn
ecting probes or test leads to the TCPA300/400, connect the power
cord from the power connector to a properly grounded power outlet.
Keep finger
s behind the protective bar rier, protective finger guard, or tactile
indicator on the probes.
Remove al
l probes, test leads and acce ssories that are not in use.
Use only correct Measurement Category (CAT), voltage, temperature, altitude,
and ampe
rage rated probes, test lea d s, and adapters for any measurement.
Beware of high voltages. Understand the voltage and current ratings for the probe
you are using and do not exceed those ratings.
The voltage rating for the TCPA300/400 depends on the probe and your
application. Refer to the Specifications section of the manual for m ore
information.
Conn
ect and disconnect properly. TCP303/305A/312A/404XL only: Connect
the probe output to the measurement product before connecting the probe to the
circuit under test. C onnect the probe reference lead to the circuit under test
before connecting the probe input. Disconnect the probe input and the probe
reference lead from the circuit under test before disconnecting the probe from the
measurement product.
Connect and disconnect properly. De-energize the circuit under test before
connecting or disconnecting the current probe.
TCPA300/400 only: Connect the probe reference lead to earth ground only.
Do not connect a current probe to any wire that carries voltages or frequencies
above the current probe voltage rating.
Inspect the probe and accessories. Before each use, inspect probe and accessories
for damage (cuts, tears, or defects in the probe body, accessories, or cable jacket).
Disable and do not use the current probe if it is damaged. Do not use the product
if it is damaged or operates incorrectly.
Examine the exterior of the current probe before you use it. Look for cracks
or missing pieces.
Use only specified replacement parts.
