Scale card
The Rate Totaliser’s units of measurement are shown on a printed scale card visible through a window at the right hand side of the display. The scale card is mounted on a flexible strip that is inserted into a slot at the rear of the instrument as shown below

• 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 instrument 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.

OPERATION

The Rate Totalisers are controlled by four front panel push buttons. When in operating mode they have the following functions:

• Grand total – shows Lo followed by least significant 8 digits of the 16 digit grand total.

• Grand total – shows Hi followed by the most significant 8 digits of the 16 digit grand total.

• If Local Total Reset CLr tot in the configuration menu has been activated, operating the & + * buttons for three seconds will reset the total display to zero and clear any pulses stored in the optional pulse output.
  The Grand Total is not reset.
