I. Overview

XMZ-J-AThe series touring inspection instrument is an intelligent instrument that uses computer technology. The instrument adopts a dual row digital tube to display the current channel number and corresponding measurement value simultaneously. The current channel also has indicator lights for display, which can be displayed at a fixed point or in a loop. The common upper limit alarm and upper limit alarm contacts are output,Each channel alarm value can be independently set, and thermocouple and thermistor signals can be freely input, which can be integrated with 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.

5、 Operation 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 press the ▼ or ▲ keys to set any value within the specified range for the parameters. Long press the ▼ or ▲ keys to achieve quick addition or subtraction; pressSETPress the ▼ key to exit the menu halfway.

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.

6、 Instrument wiring (reference):

Note: 1Printer interface wiring, this instrument usesTTLLevel interface method, ‘R’Connect the printer's busy line‘T’Connect the printer data cable,GNDConnect the printer to the ground wire, other wires do not need to be connected.

2The communication and printing functions of the instrument cannot be combined at the same time, choose one of the two.

7、 Attention:
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 turn on, ALM1The light is on,The relay is engaged;If any channel experiences an upper limit alarm,Then the channel indicator light will flash, ALM2The light is on,The relay is engaged.

5Found that the parameters cannot be changed, please check‘LC’Is it18.
