Questions and Answers

    What to do if the flame will not light on jenway PFP7 Measuring Instruments?
    • L
      Lisa LawrenceJul 31, 2025
      If the flame won't light on your Jenway Measuring Instruments, start by filling the drain 'U' tube with deionized water. Check if the fuel cylinder is empty or if the regulator pressures are incorrectly set; replace the cylinder or reset the regulator as needed. Ensure an adequate air supply by checking the air connection and the compressor's operation. If the propane/butane fuel restrictor is blocked, carefully 'blow out' the restrictor, avoiding the use of wire to prevent damage.

    Why am I getting unstable results with my jenway PFP7?
    • C
      Christy McdanielAug 4, 2025
      Unstable results with your Jenway Measuring Instruments can stem from several factors. Condensation in the air supply may be the culprit; try draining the tubing and consider using a water separator for a moisture-free air supply. The nebulizer could be blocked, so check its performance. Ensure the fuel valve is correctly set for the element being determined. A nearly empty fuel cylinder can also cause issues, so replace it with a full one. Relocate the instrument if it's in a strong draught or very bright sunlight. Also, ensure the 'U' tube is clear and the drain trap is correctly positioned. Atmospheric contamination can cause unstable results, so remove the source or improve ventilation. Ensure the instrument is always flushed with deionized water before shutdown.

    Why are my jenway PFP7 Measuring Instruments giving non-linear results?
    • S
      Steven JohnsonAug 8, 2025
      Non-linear results on your Jenway Measuring Instruments can arise from several causes. A blocked nebulizer might be the issue, so check its performance. Contaminated deionized water can also lead to this problem, so make up new standards in fresh water. Incorrect dilution or the use of an incorrect calibration standard can also cause non-linear results; prepare fresh dilutions of the calibration standard. Ensure the fuel valve is correctly set. Additionally, verify that the instrument is draining adequately by checking the 'U' tube for blockages and ensuring the drain trap is at the correct level.

    How to fix the 'unable to set standard reading' error on Jenway Measuring Instruments?
    • C
      Chelsea ThompsonAug 13, 2025
      If you're unable to set a standard reading on your Jenway Measuring Instruments, the calibration standard might be at an incorrect concentration or incorrectly diluted. In this case, make new standards to check the calibration procedure. Alternatively, the blank calibration standard may be contaminated or incorrectly set; re-make the standard and re-set the blank.

      If there is no reading on the display of your Jenway Measuring Instruments, first ensure that the correct filter is selected. If not, select the correct filter. If the calibration standard was incorrectly made, remake the standard. A completely blocked nebulizer can also cause this issue, so check the nebulizer performance.

    Why is my jenway PFP7 Measuring Instruments getting no electrical power?
    • D
      daviskellyAug 21, 2025
      If you're experiencing a lack of electrical power with your Jenway Measuring Instruments, start by ensuring the AC supply is fully engaged by checking that the power lead is correctly inserted. If the issue persists, verify that an AC supply is available by checking the mains supply.

    What causes the 'unable to set blank' error on jenway PFP7 Measuring Instruments?
    • C
      Caroline MayerAug 26, 2025
      If you're unable to set a blank on your Jenway Measuring Instruments, it could be due to a contaminated blank. Try remaking the blank and re-checking. Another possible cause is a burner encrusted with salt; clean the burner and ensure that the cleaning procedure is carried out more frequently.
