PicoScope 4444 differential oscilloscope
PicoConnect 442 probe: 1000 V CAT III test leads
The PicoConnect 442 is a passive
differential voltage measurement
probe with 25:1 attenuation and
10 MHz bandwidth. It is rated for use
up to 1000 V CAT III, and using this
probe with the PicoScope 4444 is
the most cost-effective way to make
these measurements safely on multiple
channels. With no need for a battery
pack, the PicoConnect 442 is suitable
for short- and longer-term voltage
measurements.
The probe is double-insulated to
eliminate the need for a safety ground.
It is fitted with shrouded 4 mm banana
leads and comes with a selection of
suitable test probes.
Applications for this probe include
testing the equipment listed for
Overvoltage Category III under
EN 61010-1:2010, such as measuring
voltages on distribution boards, circuit
breakers, and fixed socket outlets.
PicoConnect 441 probe: measure from millivolts to ±50 V
The PicoConnect 441 is a general-purpose passive differential probe with no attenuation and
15 MHz bandwidth, precisely measuring voltages on ranges from ±10 mV to ±50 V. The probe
is fitted with a ground reference clip, as well as the usual positive and negative leads, to eliminate
unknown common mode voltage differences between the probe and the device under test (DUT).
It uses unshrouded 4 mm banana leads, so is compatible with a wide range of test probes: it comes
with a pair of sprung hook probes.
This probe is ideal for anyone needing to make lower-amplitude, precision measurements in a wide
range of applications. You can also use it to measure the differential outputs of differential serial
buses such as CAN or RS-485.
Accessories
The convenient preconfigured kits supplied by our distributors each include three differential voltage probes with Pico D9 connectors, and a single-ended D9-BNC adaptor. These and a range of
other accessories are also available separately. See the table at the back of this document for prices and ordering information. Alternatively, you can devise your own configuration on our website,
www.picotech.com.
Note that all accessories marked with the symbol have Pico D9 connectors and can only be used with the PicoScope 4444. They have a unique intelligent probe interface, enabling the scope
device to identify the probe and set up the display accordingly.
