The paperless recorder is a display instrument that can input standard signals with sensor isolation, flow calculation, and remote communication capabilities. Our company, Yokogawa, Jiangsu, is a professional manufacturer of display instruments. Paperless recorder is a kind of professional instrument. Some customers do not understand some of the problems encountered. The following is a brief introduction to the failure of paperless recorders. And processing methods: 1, meter power does not work. Product modeling and design ability has been greatly improved, but after the completion of product design, before mass production, we must make samples to express the design idea, quickly obtain the feedback information of product design, and evaluate and demonstrate the feasibility of product design. In today's increasingly fierce market competition, time is benefit. In order to improve the competitiveness of the product market, the whole process from product development to mass production is urgently required to reduce the cost and improve the speed. The emergence of rapid prototyping technology provides an effective way to solve this problem, and has attracted much attention at home and abroad Ningbo Rongna Technology Co.,Ltd , https://www.prototyping-machining.com
A, check the instrument 220V power terminal wiring is correct;
B. Check whether the meter fuse is blown.
C. Unscrew the fixing screw behind the meter and pull the watch core out from the front. Check whether the cable between the power board and the motherboard is properly connected.
2, LCD backlight is bright, but no character and curve display.
Check that the meter shows that the cable is properly connected.
3, the channel does not enter the number, that is, change the channel signal value, the channel display value without any change.
A, using a multimeter to measure the signal on the terminal is normal;
B. Check whether the channel module switch and signal type are set correctly.
C, open the case, check the channel signal cable is connected.
4, the channel measurement value is not accurate.
A. Check whether the signal type setting in the channel parameter setting is the same as the actual access signal type.
B. The channel module switch setting is consistent with the channel signal type;
C. Check whether the signal wiring is correct and whether the signal cable is in good contact;
D. After confirming that there is no problem, recalibrate the instrument (note that the signal source accuracy must be higher than 0.1%) If the instrument calibration is not normal (cannot be calibrated), or the calibration is normal but the channel measurement is still not normal, please manufacture with the paperless recorder.
