3.By carrying out the set-up procedure in the correct order

4.By ensuring that %T or transmission is used as appropriate

5.By closing the door to the cuvette compartment before reading the result

6.By performing calibration checks after set up

7.By wiping fingerprints and spilt sample off the outside of the cuvette before measuring

8.By using the correct wavelength

PRECAUTIONS FOR USING A FRAME PHOTOMETER:

1. Do not move or Carry the unit when in use or connected to the mains electricity supply

2. There should be sufficient time for the chimney to cool before handling

3. Do not use acetylene with the flame photometer

4. Over adjustment of the fuel valve will cause excess flame

Do not position the product so that it is difficult to disconnect from the mains supply
