Table 1 Scope of Application (Reference)

Table 2 Specifications

1. Connect the power adapter and cable, then switch on the power.
2. Select the display language and actuator model on the touchscreen.
3. Press "Home" to let the device find the reference zero. It is recommended to homing before every test.
4. Once the Drawbar rests at the homing position, you can install the actuator.

1. Place the actuator on the test base at the locating sleeve.
2. Connect the actuator cable to the corresponding signal socket.
3. Lift the U-Head clamping arm out of the two square slots in the receptacle. Insert the U-Head into the slotted hole in the Drawbar, then rotate 90° clockwise to lock.
4. Press "Test" and wait for the cycle to finish.
5. Read the test result: green "OK" = pass, red "NG" = fail.
6. Rotate the U-Head 90° counter-clockwise to unlock and remove it from the Drawbar.
7. Return the U-Head to the square slots in the receptacle — do not leave it unsupported. Remove the actuator.

Figure 4 Testing Page(Voltage Input)

Reading the test graph: The horizontal axis shows the test stroke (mm); the vertical axis shows the normalized sensor output (%). A passing actuator produces a diagonal line that stays within the upper and lower red limit lines across the full stroke. If the line crosses outside the red lines, the result is NG (fail).

Note: The Settings page is intended for advanced operations such as fault diagnosis. Factory parameters are pre-configured; you do not need to access this page during normal testing.

Table 4 Description of Test Page (Fig 5):

Save Configuration feature:

• Long-press the Pra-Wolf logo at the top of the screen. Release when the indicator light on the right side of the logo turns green (approx. 3 s) to save the current model selection as default.
• Continue holding until it turns red to restore factory settings and reboot.

Table 5 Troubleshooting Reference

• Verify power plug compatibility with local outlet standards before use. Do not use mismatched connections.
• This device is rated for use at altitudes up to 2,000 m (6,562 ft) above sea level. Do not operate above this elevation.
• Do not force the power cable or adapter during insertion or removal.
• Do not use near open flames or flammable or explosive atmospheres. This device is not explosion-proof.
• Do not use in extreme environments (high or low temperature, high humidity, heavy dust).

1. Switch off power and unplug the power cable before maintenance.
2. Wipe the test bench surface with a clean soft cloth before use. If needed, use a soft cloth dampened with diluted mild detergent (do not allow liquid into the device). Allow to air-dry fully before use.
3. Do not wipe the screen with a dry cloth (scratch risk). Spray screen cleaner onto a clean cloth and wipe gently in one direction. Dry residual marks with a clean microfiber cloth.
4. Do not use corrosive liquids to clean the equipment or screen.
