    Why does the remote trigger not initiate a test on my opti-sciences Measuring Instruments?
    • M

      The remote trigger might fail to initiate a test for several reasons: * The remote trigger wire may not be correctly plugged in; check the connections. * The OS5p might not be in the correct test mode. Ensure that a cursor is not blinking in the test mode box. If it is, press the test mode key to enter the test mode. * The fluorescence signal could be too low; in this case, raise the modulation intensity.

      If the saturation light isn't triggering, it could be due to a low fluorescence signal (Ft). Try increasing the modulation intensity. If the display also blanks, you should contact factory.

      Karen HernandezAug 17, 2025
      If your unit resets during a test, it could be due to the battery not being sufficiently charged. Try charging the battery. Alternatively, the battery may be weak and require replacement; in this case, contact factory.
