7. stable band If two consecutive conversions have a difference greater than the bAnd B the filter automatically sets F 0 permitting maximum response When the difference is again within the bAnd B the filter returns to the selected F FILtEr 100 value Where B is referred to the input signal in mV band value B bAnd 100 on the 50 mV range band value B bAnd 200 on the 25 mV range Examples 1 B 5 0 mV or 0 5 mV V with bAnd 500 50 mV input range excitation 10V 2 B 2 5mV or 0 5 mV V with bAnd 500 25 mV input range excitation 5 V The factory default is bAnd 10 Decimal Point dP x xxxx XX XXX XXX XX XXXX X XXXXX dP allows selection of decimal point locations for display The locations selectable are shown in above The Increment and Decrement switches are used to shift decimal places Calibration Number CAL 00001 to 99 999 CAL is equal to the desired reading corresponding to the calibration load whether the load is actual simulated or from RCAL The number is entered prior to performing the calibration Examples 1 A 75 34 Ib weight is being used to calibrate a 100 Ib load cell CAL may be set to 75 340 75 34 or 75 3 depending on the resolution desired 2 A 10 000 Ibf load cell is known to have a rated output of 2 123 mV V A simulator with 2 mV V output is used to calibrate the 9830 CAL 10000 2 2 123 9421 FUNCTION DEFINITIONS CONT Full Scale Number FS 00001 to 999
8. 99 FS is for scaling the analog outputs of the indicator Both the 10V output and the 4 20 mA outputs are automatically scaled by FS FS the display value that corresponds to the full scale spans of the outputs either 10V or 16 mA Changing the FS has no effect until a calibration is performed The scaling is accomplished along with the calibration procedure The TARE function operates on the analog output the same as it does on the digital display The analog output is a continuously amplified analog signal even though the gain is digitally controlled Therefore the polarity of the analog output is always the same as the signal input The 4 20 mA output is unipolar and therefore must always be used with a positive input signal Examples 1 A 9830 is to read 10000 on the display and produce 5 000 V output with a 10 000 Ibf load cell loaded to capacity FS 10000 10V 5V 20000 2 A 9830 is to read 2000 0 on the display and produce a 10 mA span output with a 2000 Ibf load cell loaded to capacity FS 2000 0 16mA 10mA 3200 0 The output will then be 4 mA at zero load and 14 mA at capacity Setpoint 1 to Monitor SP1 SP1 SP1 SP1 SP1 This function allows Setpoint 1 to monitor the instantaneous peak valley or peak minus valley displays The Increment or Decrement switches are used to cycle through the various displays To signify which display is being monitored the least significant 7 segment display will be illum
