4.2 EXTERNAL POWER SUPPLY
An optional external power supply can be used with the TA325
and TA326. The requirements are a stabilised 3 V DC supply
with a minimum current output of 100 mA. The supply is to be
terminated with a 2.1 mm / 5.5 mm (0.08’’/0.219’’) power
connector (center negative).

4.3 MEASURING CURRENT
Read the safety section of these instructions before
operating this product.
Make sure the conductor to be tested is de-energized
Connect the output of the electronics to the input of an
oscilloscope or other data recording device.
The flexible current probe is not for use on conductors
with a potential of over 1000 V.
Wrap the flexible probe around the conductor to be tested
and close the coupling. Energize the circuit under test.
Locate the coupling away from nearby conductors.
