Hints and Suggestions

Preparation of Samples

Always ensure that the sample for measurement is slightly wider than the sensor and that it has a minimum thickness of 25mm. Note – this ensures that there are no reflections from the underlying surface, which could result in spurious readings.

Ensure that the product for measurement is fully defrosted, and prepared in accordance with instructions.

Operation of Fatmeter

The Operator should check the stability of the calibration settings of the Fatmeter each day on the check pad supplied before general use.

The Fatmeter should be switched on 10 minutes prior to use (this allows the meter to warm up and stabilise). Ensure that you have chosen the correct calibration setting for the product to be measured.

Ensure that measurements are taken in a consistent and repeatable manner.

Ensure that the sensor head is firmly in contact with the product. We suggest that the meter is held in a vertical position (moving the sensor from the vertical… back and forth… means that you are reading different sectors of the product, and this can affect repeatability of your measurements).

After pressing the ‘READ’ button, always allow reading to stabilise before releasing the button. Note – the reading is only stored by the meter upon release of the button.

When the displayed reading takes a long time to settle, this is a good indication that there are pockets of air in the sample. Simply press the meter further into the product (depending on thickness), thus expelling any air.

When the meter displays ‘Out of Range’, possible causes could be –

  • You have chosen the wrong calibration setting.
  • The fat specification of the product is outwith the ‘range of experience’ set for this product
  • There are large air pockets or cavities located in the product directly beneath the sensor.
  • The product thickness is insufficient.

When ‘LOW BATTERY’ is indicated on display or the display becomes very faint, means that the battery needs recharging.

Cleaning and General Care

The FATMETER is a sealed unit and is waterproofed to IP 67 prior to leaving the factory. However, we do not recommend that the unit be immersed in water or any other fluid. Tampering with the unit, opening the seals, etc., will immediately invalidate the warranty.

Your FATMETER is encased in impact resistant plastic, with the sensor head made from stainless steel and PTFE. Take care not to pierce the PTFE film – ie. avoid placing the sensor head on abrasive or rough surfaces. The unit may be cleaned with a damp cloth, using a mild solution of detergent. Be aware that some household cleaners may contain chemicals which could seriously damage the plastic enclosure. Avoid the use of any petroleum based solvent cleaners.

The unit should be charged regularly. Where the unit is in constant use, we recommend that the power supply be connected to the meter when at all possible. This will ensure that you have a fully charged battery available when necessary.

Your DISTELL FATMETER is a precision instrument. Ensure that the unit is stored securely in transit. Do not drop or otherwise misuse the equipment, as this may invalidate the warranty.
