7 Programming pulse count/litre and limit
The limit value (in litres) and pulse count/litre (calibration factor) can be pro-
grammed only with an FC programmer which is available as an option, Item
No.925-0200. Proceed as follows in order to change these values:
1. Undo the fixing screw ➂(Fig. 1) of the MSD slot Aslot A
slot Aslot A
slot A to which the cable of the
measuring device is connected for the FC and pull the MSD carefully off. The FC
remains electrically live.
2. Connect the MSD of the FC programmer to the FCFC

slot Aslot A
slot A, so that the bracket of
the MSD points to the right. The (already set) pulse count per litre is now shown
on the display: 4 digits, with the digit at the far right blinking. This pulse count
must correspond to that of the connected measuring device. You can find this
information on the relevant data sheet or on the Internet at www.digmesa.com.
If the pulse value is incorrect, it can be changed as follows.
3. Change the value of the blinking digit by pressing key . When the digit
reaches 9, it changes to 0 by pressing key again.
4. In order to access the next digit, press key . Continue changing the digit with
key until the required value is shown on the display.
5. When you have reached the last digit at the left, press key again. You will
now see a 5-digit number on the display. This number indicates the limit value in
litres.
6. Program your required value with the aid of keys and as described in
Points 3 and 4.
7. When you have reached the last digit at the left, press key again. This
confirms the entries and the display disappears. The display remains blank until
the MSD of the FC programmer is disconnected. If you wish to repeat program-
ming, press keys and simultaneously for approx. 1 sec.
8. If the MSD of the FC programmer has been disconnected, 0.00 and LITRES are
shown on the FC display. Plug the MSD which you disconnected in Point 1. onto

slot A and tighten it with the fixing screw ➂(Fig. 1). The FC is now once
again in Working mode and counts the litres on the basis of the newly set pulse
count.
