1. Installation
1) This product is used in the following environmental standards.
（IEC61010-1）[Overvoltage categoryⅡ、class of pollution 2]
2)This product is used in the following environment:Temperature range:-20 ～125℃;humidity:
45~85%RH; environment condition:Indoor use. The altitude is less than 5000m.
Caution of Installation & Wiring
Features:
3) Please avoid using in the following places：
The place will be dew for changing temperature;with corrosive gases and flammable
gas; with vibration and impact;with water, oil, chemicals, smoke and steam facilities with
dust, salt, metal powder;and with clutter interference, static electric and magnetic fields,
noise;where the air from air conditioning or heating is blowing directly; where will be
illuminated directly by sunlight; where accumulation of heat will happen caused by radiation.
4) On the occasion of the installation, please consider the following before installation.
In order to prevent heat saturated, please open enough ventilation space.
Please consider connections and maintenance environment,and ensure that there is more
than 50mm space above and below the product.
Please avoid to install the product above the machines with high the calorific value (Such as
heaters, transformer, semiconductor operations, the bulk resistance).
The surrounding environment shall not exceed the limit of using conditions.
In order to improve the anti - interference performance and security, please try to stay away
from high pressure machines, power machines to install.
Don`t install on the same plate with high pressure machine and the product.
The distance should be more than 200mm between the product and power line.
The power machine shall be installed at a distance as far as possible.
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.The influence of external resistance is about 0.3 μ
V/Ω。
2）Please use the cable with small wire resistance in the place of RTD input,and the cable
(3 wire) must be no resistance difference, The wire should be run in parallel and the cable
length should less than 5m.
3）In order to avoid the effect of noise,please wire the input signal away from meter
cable,power cable,load cable.
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, can also connect the
common-mode coil to the front-end of the signal receiving device to suppress line
interference if necessary, 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, to ensure the reliabilty of signal.
8）This product don’ t have the fuse; please set according to rated voltage 250V, rated current
1A if you need; fuse type:delay fuse.
9）Please use suitable screw force and suitable crimping terminal
Terminal screw size: see real object
Recommended terminal 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.

Method
Check the input whether is disconnected; check the FH value and FL value;
check the working environment temperature whether is normal; check the
input signal selection whether is correct.
Meter adopts RS485 Modbus RTU communication protocol, Read function code 0x03 of the
holding register in zone 04, write function code 0x10/0x06. Adopt 16 digit CRC check, the
meter does not return for error check. The data type is a 16 bit signed or unsigned integer.

IX. Communication procotol
1. Read register
For example:Host reads SV(PV1 = 200）
The address code of SV is 0x2000 ("0x" represents for hexadecimal), because SV data type
is a 16-bit integer (2 bytes),seizes 1 data register. The memory code of decimal integer 200
convert to hexadecimal code is 0x00C8.. Note: When reading data, should determine the
decimal point position firstly and then convert the reading data to obtain the actual value.

Handling of abnormal communication:
When abnormal response，put 1 on the highest bit of function code. For example: Host request
function code 0x03,and slave response function code should be 0x83.
Error code:
0x01---Illegal function: the function code sent from host is not supported by meter.
0x02---Illegal address:the register address designated by host beyond the address range of meter.
0x03---Illegal data: Date value sent from host exceeds the corresponding data range of meter.
2. Write multi-register
For example:Host use 10 function code write SV（SV=150）
ADD code of SV1 is 0x2110,because
SV1 data type is a 16-bit integer (2 bytes),seizes 1 data
register.
The decimal integer 150 convert to hexadecimal code is 0x0096. Before writing the data,
you should convert the data to the corresponding magnification and then writing the data into the
instrument.
