Solenoid Testing Modes
Electric test of the solenoid
The electrical continuity (open or short circuit) and resistance of the solenoid is tested by observing the values of the current consumed by it (PASS/FAIL check)
Manual mode
The solenoid is tested by manually varying the operating voltage duty cycle (0-100%) and the inlet pressure, while monitoring the current, pressure, and temperature.
Automatic mode (Script)
The solenoid switches automatically according to a user-defined test script. During the script, the average voltage (controlled by duty cycle), the rate at which the voltage increases or decreases with time, as well as duration of any static voltage are sequenced automatically. The user can choose a prewritten sequence (script) from the extensive library or create their own.
Automatic mode 1
Depending on the user settings, this mode partially or completely repeats the specified script(script) in a cyclic mode. It allows repetition indefinitely as all parameters are switched automatically. The mode is stopped by the operator. It is used for long-term solenoid testing. In this mode, it is possible to display current and pressure parameters of the solenoid in real time with overlay of the reference result from the library. Any test results (for example, “before” and “after” solenoid repair) can be used as a reference.
Automatic mode 2
This mode is similar to the mode 1. It is used when two independent parts have to be “looped” in time in the test script. For the first half Automatic mode 1 is used, for the second half – Automatic mode 2 is used. In this mode, it is possible to display the current and pressure parameters of the solenoid in real time with the overlay of the reference result from the library.
Real-time mode
It is available in all automatic test modes. Live displays of the values of the current and pressure are shown on the chart in real time.
Library of reference results
The vast experience of the Hydra-Test team collected over the years has allowed us to accumulate a large database of test results. Based on this, we have created an extensive library of reference results, which include tests for all of the common automatic transmission models available in the market today. This library allows new users with at a novice level of test experience to successfully be able to test and qualify solenoids. As for professionals, they are given a vast library good test samples and statistics for scrutiny for any unusual “non-standard” behavior of tested solenoids. This significantly reduces the rejection of “suspicious” solenoids, giving the operator confidence in the results that they achieve. The reference results provided with the purchase are also templates for users to create their own library from, making the process simple and entertaining.
High-precision electronics
-
For high-precision measurements of the solenoid test parameters, the Hydra-Test team employs an ADC with 12 bits of resolution, which allows current measurements with an accuracy of 0.001 Amps and pressure measurements with an accuracy of 0.10 PSI (0.005 bar).
-
The standard sampling period is 0.001 seconds (1 kHz), allowing you to track even the smallest changes in the behavior of the solenoid under test. As an option, the sampling frequency of current readings can be increased to 50 kHz.
-
The standard operating voltage frequency range of the solenoid is 100 Hz to 3 kHz. An optional expansion of up to 50 kHz is possible.
-
The standard duty cycle duration can be changed in steps of 1%, with 0.5% being optionally available.
-
An optional a hydraulic fluid temperature sensor with the measurement accuracy of 0.2 °F (0.1 ℃) can be added to the system.
ADD-ONS: Ultrasonic Cleaner
An additional ultrasonic cleaner can be added to your HT-SOL 25 test machine to clean solenoids before you test. Cleaning them before testing will make sure your testing process is not influenced by debris and dirt of dirty solenoid. It will also keep the fluid in your machine cleaner and decrease the frequency you need to change the fluid.

5 minutes cycle with automatic shut-off
-
35 watt ultrasonic element
-
40 kHz ultrasonic frequency
-
Tank size (LxWxH) inches – 6.10 x 3.75 x 2.00

ADAPTERS
Hydra-Test offers an ever-increasing line of solenoid test blocks that allow you to test each solenoid hydraulically, just like it performs in the vehicle while being able to see leaks, potential wear, or other functional issues that would be impossible otherwise. Our dedicated engineering staff is continually developing new test blocks to cover the latest transmission solenoids on the market before they get to your shop. These blocks are made from precision machined aluminum to keep them light and easy to install in the machine. High quality quick connect hose connections to the machine allow for leak free and secure connections for accurate readings.
Newest development - 0AM (DQ200)
The new 0AM valve body testing tool serves as an add-on to an existing Hydra-Test solenoid tester or VB tester running on HTC. It is driven and controlled very similarly to a standard adapter plate.
The 0AM (DQ200) tool verifies:
• Pump performance
• Pump motor degradation
• Pressure loss
• Solenoid Amperage
• External and internal leaks

MORE INFORMATION
Testing Multiple solenoids with the HT-SOL 25: Normally the test blocks are designed to test one solenoid at a time with dedicated test holes for each type of solenoid and a test harness designed to connect to the individual solenoid. Scripts are written to test the singe solenoid and display the result graph when complete.
If you have a need for higher volume, Hydra-Test can supply custom adapter blocks that have 5 duplicate holes and dedicated harnesses that allow you to sequentially batch test up to 5 of the same solenoids at a time. The test script will be written to test each solenoid sequentially instructing the operator to move the input/output pressure hoses from solenoid to solenoid as the test progresses. At the end the result graph for all five solenoids will be displayed.
For very high volume or remanufacturing customers, the HT-Multi- Sol EOL Test Machine has been developed. This machine will allow the operator to test up to 16 solenoids sequentially wit a fully automated machine with the ability to program pass/fail parameters that can be set and controlled by the customers engineering department. Please see https://www.hydratest.co.uk/ht-multi-solenoid-eol.
Solenoid models that can be tested: We currently have 30+ transmission Solenoid test blocks available; these cover virtually all of the late model common solenoid types used in transmissions worldwide. New solutions can be provided within our ever-expanding list of development projects. If you have a transmission model (new or old) that we do not have a test block for, we can make it for you. Sample solenoids may be required.
Writing own solenoid test scripts: the process of writing your own test data has been simplified greatly from the previous generation machines. A basic tutorial is given in the HT-VBT Deluxe guide starting at 10:33.
