My particle counters touch screen is not responding properly.<\/strong><\/p>\n

Many of our particle counters viable samplers and even the ScanAir pro have a built in screen calibration. Performing the screen calibration is simple. <\/p>\n

    \n
  1. With the unit powered off hold the touch screen with one finger<\/li>\n
  2. Power on the unit<\/li>\n
  3. The unit will prompt you to perform the screen calibration<\/li>\n
  4. Follow the on screen instructions<\/li>\n
  5. Once complete cycle the power on your instrument <\/li>\n<\/ol>\n

    This is how you perform a screen calibration on many of our instruments. If this method does not work please contact our technical support team to run you through more trouble shooting steps.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

        Using a Serial Connection<\/strong><\/p>

        Not being able to download data from your particle counter over a serial connection usually has one of two root causes.<\/p>

        1. The Cable is broken or damaged<\/p>

        To trouble shoot this inspect both ends of the cable for any sign of bent pins abnormal wear or cuts If the cable looks good continue to step two<\/p>

        2. Download the correct drivers for serial<\/p>

        If you have a computer you have never downloaded data with you may need to download\u00a0 appropriate\u00a0the drivers which can be found\u00a0HERE\u00a0<\/a>.<\/p>

        If you still cannot connect to your instrument feel free to contact tech support by either submitting a tech support form<\/a>\u00a0or using the live chat function on the bottom right of your browser.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

        The ApexZ portable particle counter has the industries longest battery life. As we all know over time batteries begin to lose their efficiency,<\/p>

        The ApexZ batteries have a sleep mode feature to reduce self discharge if the lithium-ion battery fully reaches 0% the cell could be permanently damaged. This feature prolongs the batteries life.<\/p>

        If the battery is removed from the instrument and stored the battery will enter\u00a0sleep mode.\u00a0Which\u00a0provides a minimum of 6 months shelf life, when stored at 20\u2103.<\/p>

        To bring the battery pack out of sleep mode simply insert it into the ApexZ and apply power or put the battery pack on the charger.\u00a0<\/strong><\/p>

        Packs should never be allowed to discharge to zero capacity in storage.<\/p>
