Inserting flexible strip carrying scale card into slot at the rear of Rate Totaliser.Thus the scale card can easily be changed without removing the Rate Totaliser from the panel or opening the instrument enclosure. New Rate Totalisers are supplied with a printed scale card showing the requested units of measurement, if this information is not supplied when the Rate Totaliser is ordered a blank card will be fitted. A pack of self-adhesive scale cards printed with common units of measurement is available as an accessory from BEKA associates. Custom printed scale cards can also be supplied. To change a scale card, unclip the protruding end of the flexible strip by gently pushing it upwards and pulling it out of the enclosure. Peel the existing scale card from the flexible strip and replace it with a new printed card, which should be aligned as shown below. Do not fit a new scale card on top of an existing card.
- Align the self-adhesive printed scale card onto the flexible strip and insert the strip into the Rate Totaliser as shown.
