Currently backoreder. ETA late July.

Designed to offer uncompromising resolution and accuracy, the Pico automotive diagnostic pressure transducer allows quick and accurate pressure analysis of many automotive systems, with:
* three pressure ranges
* a zoom tool
* integrated bleed-off / pressure relief valve

Accurately measure pressure to 500psi

Ultra fast 100μS response time

Zoom feature for enhanced analysis capabilities

Rechargeable Li-PO battery

Integrated pressure relief / bleed-off valve

Auto Zeroing

High noise immunity

Temperature compensated

This unit is an auto zeroing pressure transducer designed to offer form and flexibility to automotive diagnostics.

What Lab Scopes does the WPS500X Transducer work with?
The Pico WPS500X Transducer works with all modern automotive and industrial lab scopes, including, but not limited to: PicoScope, Snap-on scopes, Fluke ScopeMeters, Bosch scopes, etc... However, lab scopes with banana inputs require a banana to BNC Male adapter.

Zoom Modes

The zoom feature operates by removing all of the voltage from the signal below 100 Hz and then magnifying the remaining signal.

Zoom 1: This mode multiplies the signal 10 times.

Zoom 2: This mode multiplies the signal 100 times. For example, let* say the transducer is connected to intake manifold vacuum on a running engine at idle with
the transducer set to mode 2 (-15 to +50 psi or -1 to +3.45 bar) and the waveform on the scope is at -9 psi (-0.6 bar). The fluctuation in the signal caused by the
valves?opening and closing compared with atmospheric pressure forcing air into the manifold will be visible but will only make up a small portion of the overall signal.
Selecting the zoom function will bring the waveform up to the zero line (remove the -9 psi portion) and the fluctuations will be magnified, making analysis of this
component of the signal much clearer.

Zoom 3: Zoom level 3 multiplies the signal by about 1,000 times. It is extremely sensitive and is suitable only for vacuum measurements.




Fluid Compatibility

The WPS500X is suitable for use with the following types of fluid:
- Brake, clutch and other hydraulic fluids
- Gasoline and diesel
- Air
- Water




The Pico WPS500x features three output ranges:


Range 1: The first range measures from -15 psi (-1 bar) to +500 psi (34.5 bar).
It offers high resolution and accuracy for high-pressure tests such as cranking and running cylinder compression or fuel pressure testing. It is also helpful for identifying cam timing issues such as jumped timing belts and stretch timing chains, especially on multi-cam engines that may not have a cam sensor on each camshaft. The WPS500X kit includes a specially designed compression hose for performing this test with a significantly reduced error and higher operating temperature range than conventional compression hoses and adapters.


Range 2: The second range measures from -15 psi (-1 bar) to +50 psi (+3.45 bar).
This range is ideal for vacuum test and fuel system tests. When testing these systems the zoom function is especially useful to analyze valve operation with the vacuum waveform or the injectors through the fuel waveform.


Range 3: The third range measures -5 to +5 psi (-0.345 to +0.345 bar).
This setting is sensitive enough to analyze small pressures or pulses such as exhaust pulses from the tail pipe.
