2.1. GENERAL The F126-P-EL-TA may only be operated by personnel who are authorized and trained by the operator of the facility. All instructions in this manual are to be observed. Take careful notice of the " Safety rules, instructions and precautionary measures " in the front of this manual. -
Page 8: Operator Information And Functions
2.3. OPERATOR INFORMATION AND FUNCTIONS In general, the F126-P-EL-TA will always function at Operator level. The information displayed is dependant upon the SETUP-settings. All pulses generated by the connected flowmeter are measured by the F126-P-EL-TA in the background, whichever screen refresh rate setting is chosen. -

All instructions in this manual are to be observed. - Page 10 Page 10 Matrix structure SETUP-level: SCROLLING THROUGH SETUP-LEVEL Selection of function-group and function: SETUP is divided into several function groups and functions. Each function has a unique number, which is displayed below the word "SETUP" at the bottom of the display. The number is a combination of two figures. The first figure indicates the function-group and the second figure the sub-function.

Page 14: Flowrate
Page 14 2 - FLOWRATE The settings for total and flowrate are entirely separate. In this way, different units of measurement can be used for each e.g. cubic meters for total and liters for flowrate. The display update time for flowrate is one second or more. Note: these settings also influence the analog output. -
Page 15: Power Management
When used with the internal battery option, the user can expect reliable measurement over a long period of time. The F126-P-EL-TA has several smart power management functions to extend the battery life time significantly. Two of these functions can be set:... -

Page 20: Analog Output
Page 20 7 - ANALOG OUTPUT A linear analog (0)4-20mA or 0-10V signal is generated according to the flowrate with a 10 bits resolution. The settings for flowrate (SETUP - 2) influence the analog output directly. The relationship between rate and analog output is set with the following functions: The analog output can be disabled. -
Page 21: Communication (Optional)
Page 21 7 - ANALOG OUTPUT (CONTINUED) This function is used to stabilize the analog output signal. FILTER The output value is updated every 0.1 second. With the help of this digital filter a more stable but less precise reading can be obtained. The filter principal is based on three input values: the filter level (01-99), the last analog output value and the last average value. -
