Whenfinish set each number, press this key to each number again, then all number will flash, itmeans the parameter is setted. When the display is close, press this key, the display willappear; when working, press ths key 5 second, the backlightwill close, press 5 secondagain, it will be open[ADD]When set the parameter, press this key, the “flash number” will add 1; it could confirmthe radix point too.GE-1203 Ultrasonic Level MeterA.YITE TECH http://www.ayite.net tech@ayite.net* P1 Parameter* P2 Pagethe P2 page is used for engineer, if need change the value, just connect with the producer. Weadvise, don’t change the P2 page* Serial communication protocol[Standard Baud Rate]The system uses the asynchronous half-duplex communication, the baud rate could be600~19200bps.1. Master Meter: sent the address (1-64), then receive the data2. Slave meter: Answer the master meter by stop, each frame sent 21 BYTEThe first 5 BYTE is water depth (5 BYTE ASC code, the unit is meter)the BYTE 6~20 just for test in produce, no need pay attention21st BYTE is Checksumse.g. the below is a data sent by the meterInto settingWhen meter working, press [PAG], it will display “ Menu choose SetP1”, then press [MOV], it will show “Lower limit 00000”, you willstart to change the parameter, the parameter will display as below,one by oneLower limitLow Limit, if the meter don’t have the relay function, press [PAG] tonext parameterUpper limitHigh Limit, if the meter don’t have the relay function, press [PAG] tonext parameterCurrent mode Work pattern, pre-set:MOD-S. press [PAG] to next parameterDifferenceIt is used to set the measure pattern1. if set the value as zero, it will display the value of the distancefrom the sensor to the target2. if set the value as the height of sensor, from the sensor to thebottom, but it could not excced the measure range; meter willdisplay the value from the surface to the bottomWhen display “Difference 00000”, press [ADD] and [MOV], setsuitable value; when the final digit is flashing, press [MOV ] again,the meter will save the setting; the setted value will display on theleft…press [PAG] to next parameterAddresscommunication address, press [ADD] and [MOV], set suitable value;press [PAG] to next parameterBaud rate Similar as the above?Emission power For ultrasonic emission power, the value could be 1-20, pre-settedquit Press [PAG] more than 3 second, quite parameter setting?GE-1203 Ultrasonic Level MeterA.YITE TECH http://www.ayite.net tech@ayite.net30 2E 35 30 31 31 31 33 2E 37 36 31 41 5C 2D 86 3F 00 4D B5 E6----- level = 0.501m(30 2E 35 30 31) ;----- 6~20 just for test in produce;----- E6 is ChecksumsInstallationRightThe Surface should be equable, avoid the blenderWrong1. the liquid level could notexceed the blind area2. keep distance from theliquid feed port3. if install outside, care forthe sun and rain4. the distance is calculatedfrom the bottom of sensor,not the top of sensorWrong conditiona. the sensor not verticalb. near the wallc. near the feed port
