Allen Face > Technical Support

Our products are designed and manufactured to very high standards and should provide you with years of service. We stand behind our products and offer the required recalibration and service to keep your equipment in optimal shape.

Once you have your F-Meter or D-Meter, you will need to use the Download Manager software - provided free at the link below - to transfer the data from your Meter to your PC. Microsoft Excel is required.

We have also provided a link to the Sewell website for details and assistance with the USB to Serial Adapter that shipped with your equipment.

If you have a problem that is not addressed here, please give us a call directly at (224)699-9000 or send an email to
