4. PROGRAMMING THE IDENTS AND UNIT LABELS (L/M, PPH, ETC)
1) When in any mode, select the display to be altered using the
ÇÈ keys. Note if you are a curve menu you
change the units only, this will change all points in that curve.
2) Press the SHIFT key followed by the EXP/UNIT key and the cursor will begin to flash at the far right hand
side of the display.
3) Use the
ÇÈ keys to select the required character for that position and the ÅÆ keys to alter the position of
the cursor. Using these key, the units on the right hand side may be altered.
4) To move the cursor to the left hand side of the display press the ALTER key and the cursor will move
across.
5) Use the
ÇÈ keys to select the required character for that position and the ÅÆ keys to alter the position of
the cursor. Using these keys the display designation may be altered.
6) Once the desired characters have been programmed then pressing the ENTER key will store them in that
display.
7) Use the
ÇÈ keys to select another display to be altered and repeat the above stages.
IMPORTANT NOTE: Where a maximum number of digits are to be displayed e.g. on total, it is advised
that the display designation is limited to four or fewer characters, otherwise the displays will overlap
causing apparent corruption. If this should occur then the number of characters for the display
designation should be reduced, after which the display will return to normal.
In some cases the unit may prevent changes to the display. This is because the instrument needs to
have these displays fixed to run correctly. See any special instructions supplied.
5. FREQUENCY INPUT CARD (EDIT CURVES) K FACTORS VS. F/V
This section describes how to program the Flow Curve, which the machine uses to compute the flow rate, by
using The K factor (counts per unit measured) and frequency /viscosity.
1) Display shows ‘EDIT CURVE 1’ or 2 or 3.
2) Press ALTER to display the first point of calibration. Then use the ÇÈ keys to select the required calibration
point to be entered or altered. The left hand display will always show the curve and point number i.e. C 101 , the
right hand display will show the units, i.e. Hz, Hzv, L/M etc. This label can be changed by pressing the SHIFT
then UNIT key.
3) To enter/alter data either press the CLEAR key or enter a numeric value. The machine reads from the lowest
to highest K factor and frequency/viscosity, so they should be programmed lowest (first) to highest (last). The
display will show SET on the left indicating that data is being entered. To obtain +/- values press the SHIFT key
followed by the +/- key. To obtain EXP values enter the numeric value followed by the EXP key and the
exponential value. Press the CLEAR key to delete incorrect data entry.
4) Having entered the correct value, press the ENTER key and the entered data with the channel and point
number will be displayed
5) Use the ÇÈ key to select the next point of calibration or press the ENTER key to exit this mode and return to the list of
program options.
