Vacuum and Pressure Tubing Notice for ADC-2500 Series Air Data Calibrator

This is a notice to all TestVonics Air Data Calibrator users. We have had several calls from users who are finding a Track loss during Auto Exercise. TestVonics found several users using 1/4” tube with an adapter fitting(s) from the vacuum source to the rear panel and getting a track loss condition. For this reason we are releasing this notice for all users to check the following:

  • Vacuum Source Hoses - The hosing from the vacuum source to the ADC rear panel must be at least 3/8” diameter. TestVonics recommends MIL-H-5593-6 hosing to meet this requirement. TestVonics offers a Vacuum Hose Assembly (Part No. ADC-2500-VAC-1-08) for purchase that meets this requirement.
  • Pressure Source Hoses - The hosing going from the pressure source to the ADC-2500 rear panel must be at least 1/4” diameter. TestVonics recommends using MIL-H-5593-4 hosing from the Pressure source. TestVonics offers a Pressure Hose Assembly (Part No. ADC-2500-PRES-1-08) for purchase that meets this requirement.

TestVonics has Vacuum and Pressure Sources available for purchase if an adequate source is not available.

What is the best way to power off the ADC-2500 Calibrators?

The ADC-2500 operates on a custom embedded operating platform. Most ADC-2500 systems do not have a built-in write filter to protect the OS from sudden shut downs. All ADC-2522, ADC-2550, and ADC-2555 systems feature write protection, but should still be powered down as instructed below. The safest way to power down the ADC-2500 Series is as follows:
  • Locate the 'Start' button in the lower left corner
  • Select the 'Shut Down' option from the menu
  • They system will shut off, when the screen turns white, switch off the Power
