2.Cable caution：
1)Please use specified compensation wire in the place of TC input;Please use insulated TC if the measured device is heated metal.
2)Please use the cable of lesser resistance in the place of RTD input,and the cable(3 wire) must be no resistance difference,but the total
length is within 5m.
3)In order to avoid the effect of noise,please put the input dignal away from meter cable,power cable,load cable to wiring.
4)In order to reduce the power cables and the load power cables on the effect of this product,please use noise filter in the place
where easy to effect.You must install it on the grounding of the disk if you use the noise filter,and make the wiring to be shortest
between noise filter output side and power connectors.Don`t install fuse and switch on the wiring of noice filter output side,otherwise it
will reduce the effect of noise filter.
5)It takes 5s from input power to output.If there is a place with interlocking actions circuit signal,please use timer relay.
6)Please use twisted pair with a shield for analog output line,to ensure the reliabilty of signal.
7)Please use twisted pair with a shield for remote RS485 communication cable,and deal with the shield on the host side earth,
otherwise it will reduce the effect of noise filter.
8)This product is not the fuse;please set according to rated voltage 250V,rated current 1A if you need;fuse type:relay fuse.
9)Please use the suitable screw force and crimp terminal.
The screw terminal size:
M3X8 ( with 6.8X6.8 square base)
Recommended tightening torque: 0.4N.m
Proper cables：0.25～1.65mm single cable/multiple core cable
10)Please don`t put the Crimp terminal or bare wire part contact with adjacent connector.

1. High/low point display setting function
Example: use electronic ruler or others to measure distance, if want position 5mm display 500, position 6mm display 600, firstly
enter function shielding menu to set SF1= Y(open CAS, CAK parameter), then while the position is at 5mm, enter the menu to set
CAS=500; while the position is at 6mm, enter the menu to set CAS=600. After exit the menu, it will corresponding indicate 500~600
between 5mm and 6mm.
2. Linear signal self-calibration function
a）Set INP type, and make sure it is one of the linear signal.
b）The input signal should be applied to the correct input channel.
c）Enter low limit calibration menu CAL, press “ ” to flash “YES” ; after adjusting the input signal to the minimum value, then
input it to the meter.
d）When “YES” flashing, and the minimum value of input signal has been inputed into the meter; press “ ” to confirm and save
calibration value.
e）After the low limit is calibrated, enter high limit calibration menu CAH, and flash “YES” in the same way.
f）Adjust the input signal to the maximum value, and input it into the meter. And when “YES” flashing, press “ ” to confirm
and save calibration value of high limit.
g）After calibration, enter CAE to change “N” into “Y” to enable self-calibration; otherwise, it will use the default calibration value.
h）The calibrated high limit input value of linear signal should not fall outside the input standard range ±10%.
i）After the calibration, if the result is not satisfactory, it can be recalibrated.
3. Analog range calibration function
Example: actual high limit is 20.4mA, low limit is 3.97mA. To calibrate the analog range through the modification of OLL, OLH.
OLL= (Preset analog low limit - actual analog low limit)/ actual analog range*1000 =( 4.0 - 3.97)/(20.4 - 3.97) * 1000 = 2
OLH= (Preset analog high limit - actual analog high limit)/ actual ananlog range*1000+1000 = (20.0 - 20.4)/( 20.4 - 3.97) * 1000 +
1000 =976

Methods
Checks whether the input signal connects or not, whether the figure of FH/FL value is too small, whether
input signal is selected correctly, whether working environment is normal.
Meter adopt Modbus RTU communication protocol, RS485 half duplex communication.Read function code:0x03,
write function code 0x06 or 0x10. Adopts 16 digit CRC check, the meter does not return for error check.
Data frame format:
Start bit
Data bit
1 8 1No
Stop bit Check bit
Abnormal communication processing:
When abnormal response，put 1 on the highest bit of function code. For example: when host request function code is 0x03, slave
response function code should be 0x83.
Error code:
0x02---Illegal address: the register address designated by host beyond the address range of meter.
Communication cycle:
Communication cycle is the time from host request to slave response data . ie: communication cycle= time of request data sending
+slave preparation time + response delay time + response return time.
Eg: 9600 Baud rate: communication cycle of single measured data ≥ 250ms.
1 Read register（0x03）
For example: Host reads integer AL1（AL1=200）
The address code of AL1 is 0x3201, because AL1 is integer( 2 dyte), seizes 1 data register. The memory code of decimal integer
200 is 0x00C8.
Note:It should read DP value or confirm DP menu value first to ensure the decimal point postion when reading data,and converse
the reading data to get the actual value. On the contrary ,it should converse the data to corresponding ratio first before writing the
data into meter.

For example: Host writes AL1（First alarm set value 100）
The address code of AL1 is 0x3201, because AL1
is integer ( 2 dyte), seizes 1 data register. The hexadecimal memory code for decimal
integer 100 is 0x0064.
