    Why PG7601 motorized rotation will not engage in DH Instruments ADCS-601?
    • B
      beannancySep 8, 2025
      If the PG7601 motorized rotation will not engage on your DH Instruments Test Equipment, the motorized rotation system may be recovering from an overload, or the measurement made is absolute by vacuum and the reference vacuum is not under the Ready limit. Wait 25 seconds for the system to recover.

    What to do if ADCS component displays or in DH Instruments ADCS-601?
    • D
      Dawn HahnAug 23, 2025
      If the ADCS component of your DH Instruments Test Equipment displays or where a numerical value should be, it means the number to be displayed is too large for the allocated space. This is usually due to an erroneous setting or measurement causing an out of limit high value to be calculated. Check the settings that may be causing an out of limit high measurement and adjust if necessary.

    Why is automated pressure generation extremely slow in DH Instruments ADCS-601 Test Equipment?
    • J

      If automated pressure generation in your DH Instruments Test Equipment is extremely slow or the pistons never float, the test volume might be too large. Try reducing the test volume.

    How to fix vacuum pumps that will not run on DH Instruments ADCS-601 Test Equipment?
    • G
      George MontgomeryAug 28, 2025
      If the system’s vacuum pump(s) of your DH Instruments Test Equipment will not run, the fuse on the AC2 or AC3 power supply connection may have blown. Replace the fuse on the AC2 or AC3 IEC power connector on the rear of the Control Cabinet. The fuse should be a 250 VT 10 A.

    Why is FPG8601 pressure indication unstable in DH Instruments ADCS-601?
    • A
      Angela BarnettSep 16, 2025
      If the FPG8601 pressure indication is unstable when the FPG8601 is bypassed (vented) in your DH Instruments Test Equipment, the piston-cylinder may need to be cleaned. Clean the piston cylinder.

    Why PG7601 automated pressure control is not starting in DH Instruments Test Equipment?
    • R
      Robert HenrySep 4, 2025
      If the PG7601 automated pressure control (GEN) is not starting after setting a target and loading mass, and the measurement mode is absolute by vacuum in your DH Instruments Test Equipment, it is because in absolute by vacuum measurement mode, before automated pressure generation begins, the reference vacuum must be below 20 Pa. Wait for the vacuum to reach less than 20 Pa, and check and correct the vacuum supply if it is inadequate.
