I. Overview

XMZ-JThe series touring inspection instrument is an intelligent instrument that uses computer technology. The instrument adopts dual row digital tubes to display the current channel number and corresponding measurement value simultaneously. The current channel also has indicator lights for display, which can be fixed-point or circular display. The upper and lower limit alarm contacts are output,Thermocouple and thermistor signals can be freely input and connected to a computerRS485Serial communication or driver micro print timing printing, communication protocol adopts internationally recognizedModbustuAgreement, able to communicate withPLCOr the touch screen can be connected to form a centralized control and management system.

2、 Main technical indicators of the instrument:

1、 Accuracy: ±0.5%F·S±1.0a character (Note: The sensor needs to be isolated from the external metal shell).

2、 Input signal and temperature measurement range:K（0～1300℃）、E（0～800℃）、J（0～1000℃）、S（0～1600℃）、R（0～1700℃）、

N（0～1400℃）、Pt100(-200.0～600.0℃) Cu50（-50.0～150.0℃）

3Alarm relay contact capacity:220V 3A(obstructive)

4Working power supply: AC220V±10% 50HZPower consumption less than5W

5Normal working environment: temperature0～50℃, relative humidity35%～85%Non corrosive gas environments

4Operation of instruments

1The normal display status of the instrument

① In normal use, the upper display window shows the temperature value measured in the current channel, the lower display window shows the current channel number, and the current channel also has indicator lights displayed. When setting parameters, the lower row displays the parameter symbol and the upper row displays the set value.

② PressSETkey3In seconds, you can enter the parameter menu and pressThe ▼ key or ▲ key can be used to set any value within the specified range of parameters. Long pressing the ▼ key or ▲ key can achieve fast continuous reduction or addition; pressSETKey&Press the ▼ key to exit the menu midway.

③ In automatic inspection mode, press the ▼ or ▲ key3SEnter channel fixed-point or loop display setting status,Press the ▼ or ▲ keys to set the value of the lower window to1～LUWhen there is a certain number of channels, the instrument will display the measured value of that channel at a fixed point,Set this value to0Or pressSETkey,The instrument returns to the cyclic display state,

④ When there is an alarm output, the alarm indicator light is on. If there is an upper limit alarm, the corresponding channel indicator light will flash; If the lower limit alarm is triggered, the corresponding channel indicator light will remain on.

⑤Printing function time parameter setting (only available with printing function):

Simultaneously hold downSETKey&▼ key, ▲ key, three keys3For seconds or more, enter the printing time setting state.

⑥Manual instant printing pressSET+▲ Key 3In seconds, the instrument will instantly print data once

2Setting of basic parameters of instruments

instrument16The measurement value address of each channel is1001H-1010H,See communication protocol for details

WuNotes:

1The equipped sensors must be isolated type.

2If all the numbers on the instrument display jumping, please check if the working voltage of the instrument is normal and make it comply with the regulations.

3After being powered on, it continues to display on the upper display window“HH”Please check if the sensor is disconnected, short circuited, or if there are any other wiring issues. 4If any channel experiences an upper limit alarm,Then the channel indicator light will flash, , ALM1The light is on,The relay is engaged;If any channel experiences a lower limit alarm, fiveThe channel indicator light is always on, ALM2The light is on,The relay is engaged.
