After SETUP/CAL is selected and a channel number has been chosen, the SETUP/CAL menu is displayed. choose DISPLAY by pressing the number “1” key + ENTER. The FILTER option can be reached by scrolling down once to view the selection number and then pressing the “4” key + ENTER. A conversion rate of 4, 15, 30 or 100 Hertz may be selected by entering its menu number
+ENTER. Enter the number of the desired A/D conversion rate and press ENTER. The normal display will return. Changes may be noticed in the flickering of the LSB on the display. In most situations, the flickering digits are an insignificant fraction of the display range and can be ignored. Should the flickering become annoying or make reading the display difficult, choose a slower rate of conversion.
NOTE: Slower rates of conversion may affect the accuracy of the TOTALIZER in situations where flow is changing often. Steady flow rates will see little loss of TOTALIZER accuracy.
10.2.6. Front Panel Lock Out
Front Panel Lockout is available only through serial communication. See the SERIAL COMMUNICATIONS section of this manual and Appendix A.
CAUTION: While the front panel is locked out, all command functions, excluding the override functions, are disabled. Commands can be overridden OPEN or overridden CLOSED during front panel lockout. This was determined to be useful both as a trouble shooting and as a safety tool. All other functions will be available only through the use of serial communication.
10.3. TOTALIZER SETUP
The TOTALIZER can be set to count up to a set point, to count down from a set point or to count up continuously to the maximum ability of the display (999999). In order for the TOTALIZER to work, a unit of measure must be chosen that includes a time element. For example, standard liters per hour (SLH) will totalize; percent (%) will not. Each mode is described in the following text and can be followed in the diagram below.
10.3.1. Count Up to a Set Point
The TOTALIZER will be set to count from zero (0) to a set point. When the set point is reached, a memory flag will be set to its logic high state. This flag is readable only through serial communications. The TOTALIZER will continue to count up to the maximum ability of the display.
While the SETUP/CAL menu is displayed, choose TOTAL by pressing the number “2” key followed by ENTER. A TOTALIZER menu is displayed. Press the number “1” key to choose the CNT UP option. The COUNT UP/DN window is displayed for the selected channel. Enter the desired set point using the numbered key pads and press ENTER. The unit returns the previously programmed display with the selected channel now displaying the Riemann Sum of the received transducer signal.
