Lab-Trax-4/24T
WORLD PRECISION INSTRUMENTS 1
Lab-Trax™ 4/24T is a 4-channel recorder that provides the high resolution and
sensitivity required for cardiovascular/hemodynamic research, organ and tissue bath
studies, oocyte clamp and epithelial voltage clamp applications. Each channel is
independent, with its own 24-bit analog-to-digital converter. This provides much higher
resolution and sensitivity over conventional recorders.
In addition, each channel input is equipped with the appropriate filters and amplification
required. This makes the Lab-Trax™ 4/24T recorder a space-efficient “one box” solution.
Setup is plug-and-play easy with connection to PC or Mac computers via the popular USB
interface.
Included Items
The Lab-Trax 4/24T is shipped with the following:
• USB Cable
• Data-Trax2™ Installation CD
(Software manual is PDF file on CD, or select “Help” from Data-Trax2 menu)
• Hardware Instruction Sheet
If any items are missing, they should be reported to WPI within 10 days of receipt.
Optional Cable
The Lab-Trax4/24T is capable of recording 'single-ended' output voltages with the use of
an adaptor cable (WPI# 300344). The cable converts the 8-pin DIN input on the LabTrax
4/24T into a male BNC connector. Use this five-foot cable to connect the 8-pin DIN
connector to the Lab-Trax4/24 and the standard BNC to an amplifier.

the gain. If no gain resistor is installed,
the gain is x1.
