Temperature巡检仪ALD807
Overview
64The road digital temperature inspection instrument adopts single-chip technology and is connected to the signal of the thermal resistance sensor, which can detect64Temperature patrol detection and control within the road. The main characteristics are
LEDDisplay the measured value, set parameters, inspect the number of routes, and directly indicate the alarm channel number with a light-emitting tube.WATCHDOGMonitoring technology prevents crashes, and digital filtering technology enhances resistance.
E2PROMData protection, all set parameters will not be lost when powered off.
Select fixed-point/inspection, and manually switch the fixed-point status to any channel. Lan YuALD807Translate into Englishselset to159.

The number of inspection routes is64Free setting within the road, alarm can be set,It can also be set to different alarm values separately
Inspection time for each route1.0-10.0Adjust freely between seconds. Unnecessary inspection channels can be hidden at will.
The potentiometer debugging of the instrument has been cancelled, and the accuracy of the instrument is reliable. Debugging only needs to be carried out on the instrument panel.
