The Pulsite Solo digital rate and totaliser with battery or dc power
Programming the Pulsite Solo Rate & Total Indicator
If both buttons are pressed together for four seconds the meter enters program mode and a request is made to enter a PIN. The display flashes between the two words “Pin” and “no”. If no PIN has been entered a press of the left key will advance the system to the next menu item. The default PIN is 0000.
With the display flashing between the two words “Set” and “unit”, pressing the right button will display a flashing unit. Each press of the right button will advance the displayed unit through a cycle of: Gal – cc – kg – gms – Ltr – blank (no units). When the required unit is flashing, a four second press of the left button will lock-in that unit and advance to the next menu item.
With the display flashing between the two words “Auto” and “Cal”, the user can self calibrate the indicator by passing a predetermined amount through the flowmeter. The electronics records the number of pulses received, calculates the pulses per “unit” as the ‘K’ factor and enters it in the “SCALE FACt” section later in the menu system. This number may be edited later if required. Any “unit” may be used, grams, cc, litres etc. This “unit” is used for both total & rate displays. The right hand key enters the volume selection routine & increments the required amount of liquid through pre-set values, 0.1 0.25 0.5 1.0 5.0 10 & 20. Before this program is continued the flowmeter must be primed and ready to discharge the pre-set amount. The larger the amount the more accurate the calibration. When the left hand key is pressed the internal counter counts the number of pulses received until the counter is stopped. The display shows “run” until no further pulses are received or the left button pressed (e.g. against a measuring cylinder) and then it shows “stop” to show the count is completed. Pressing the left key advances to the next menu item.
The scale factor is the number of pulses for a given unit of liquid. It is best to calibrate the meter in the actual running conditions. If “Auto cal” has been used before, the ‘K’ factor that the electronics calculated will be displayed. The right hand key begins the entry mode, it then cycles the number and the left hand key moves to the next digit. Holding the left key for 3 seconds advances to the next menu item.
This function permits the user to select the display function, three options are available. When the right key is pressed the display changes to the previously selected option. Further presses of the key cycle through the options, flow rate only “rate”, totaliser only “total” and switchable between rate and total “both” using the left hand key in the run mode. The right button cycles the options and the left button advances the program to the next menu item.
If either “total” or “both” mode is selected in the “disp sel” section of the program the user has the option to disable the totaliser reset button. “Yes” means the reset button works, “no” disables it. Pressing the right hand button the display shows the previously selected state, either yes or no. Pressing the right hand key changes the display, the left hand key acknowledges the choice and advances the program. Changing the choice from no to yes will not reset the counter until the right hand key is pressed in run mode.
Total Decimal Point
This sets the number of decimal places for the totaliser. The display shows a row of zeros with a decimal point. Pressing the right button moves the decimal point. When the required decimal places is shown, holding the left key for 3 seconds advances to the next menu item.
Rate Decimal Point
This sets the number of decimal places required for the flow rate indicator. The display shows a row of zeros with a decimal point. Pressing the right button moves the decimal point. When the required decimal places is shown, holding the left key for 3 seconds advances to the next menu item.
“Rate” is the time base used for flow rate display, e.g. unit volume per second, per minute or per hour. The right key enters the mode and cycles between the options “Sec”, “min” and “Hr”. Holding the left key enters the option and advances to the next menu item.
This option permits the user to alter the degree of filtration on the display. The right button cycles between ‘none – F1 – F2 – F3 – F4 – F5’. This does not affect the totaliser, just the amount the display “jitters” during normal operation and its response to step changes in flow rate. The right button cycles the options and the left button advances the program to the next menu item.
This gives the option of changing the PIN. The left key by-passes this option. If the right key is pressed the existing PIN will be displayed.. The currently selected digit will flash. The right hand button increments the selection. When the required selection is reached the left hand button moves the flashing digit to the right. Each digit can be cycled until the number you require is reached. Holding the left key enters the option and advances to the next menu item.
The word “End” shows for approximately 2 seconds before the unit exits the menu system and returns to the “run” mode.
