30 3.17 Analog adjustment Below the ANALOG ADJUSMEN screen is shown along with the keys that are enabled. In this screen the Gain and Offset parameters for the analog output are shown, and can be used for adjustment of slope and offset for the signal on the analog output. In addition the est mode, estv. and Output parameters are shown, which are identical to the corresponding parameters in the ANALOG OUPU screen described earlier. he keys are used as follows: F Moves the cursor up between the different parameters on the screen. Moves the cursor down between the different parameters on the screen. Selects change/entry of the parameter marked/selected by the cursor. Clr Return to the ANALOG OUPU screen. >0< Analog Gain parameter he analog Gain parameter can be used to adjust the slope of the signal on the analog output (4-20mA or 0-10V). he Gain parameter can be set from to , and is a factor that is multiplied onto the analog output signal. hus corresponds to no slope adjustment of the signal from the Digital-Analog-Converter (DAC) of the 5024 terminal. Note: Depending on whether the slope of the signal should be increased or decreased, then the Gain value must be larger or smaller than Analog Offset parameter he analog Offset parameter can be used to adjust the offset (displacement) of the signal on the analog output (4-20mA or 0-10V). he Offset parameter can be set from to +1000, and is a number that is added onto the analog output signal. Hence a parallel displacement of 0.01mA of the analog ma signal requires an Offset value of approximately 33, while a parallel displacement of 0.01V of the analog Volt signal requires an Offset value of approximately 66. hus an Offset value of 0 corresponds to no offset adjustment of the signal from the Digital-Analog-Converter (DAC) of the 5024 terminal. Note: Depending on whether the signal is to be moved up or down, then the Offset value must be positive or negative. Page 28 Instruction Manual, 5024 Weighing erminal

31 Analog trim procedure o trim the analog output signal the following procedure can be used: 1) A measuring instrument is connected to the used analog output (ma or Volt). Connection of other external equipment on the analog output is removed. 2) Ensure that change of parameters is not locked by entering the correct password in the SYS- EM screen. 3) Switch to the ANALOG ADJUSMEN screen. 4) he Gain and Offset values are set to their default values ( and 0 respectively) corresponding to no adjustment. Possibly make a note of the orignial values. 5) Set the est mode parameter to ON. 6) Set the estv. parameter to the minimum value (4.00mA or 0.00V). 7) Make a note of the value measured with the connected measuring instrument (MinValmA or Min- ValVolt). 8) Set the estv. parameter to the maximum value (20.00mA or 10.00V). 9) Make a note of the value measured with the connected measuring instrument (MaxValmA or MaxValVolt). 10) Calculate a gain value as one of the following: Gain ma = / (MaxVal ma - MinVal ma ) Gain Volt = / (MaxVal Volt - MinVal Volt ) 11) Enter the found value in the Gain parameter. 12) Set the estv. parameter to its minimum value (4.00mA or 0.00V). 13) Set the Offset parameter to a suitable value so the measuring instrument shows 4.00mA or 0.00V. his is done, as a displacement of 0.01 ma requires an offset of approx. 33, while a displacement of 0.01V requires an offset of approx. 66. Depending on whether the signal is to be moved up or down, the Offset value must be positive or negative. 14) For different estv. values in the entire interval (4-20mA or 0-10V) verify that with the found Gain and Offset parameters correct values are measured on the analog output. 15) If needed perform a fine adjustment of the found Gain and Offset values. 16) Make a note of the found values for the Gain and Offset parameters. 17) Connect the external equipment instead of the used measuring instrument. 18) IMPORAN: Remember to set the est mode parameter to OFF. 19) IMPORAN: Remember to lock for parameter change in the SYSEM screen.
