XSEW Digital Display Instrument
■0.05 level precision, measurement and control speed of 10 ~400 times per second can be set
■Display range-99999~99999
■Analog quantity is universal input, selected by setting
■The 1-4-point alarm output is optional. It includes seven basic alarm methods, including measurement upper limit, measurement lower limit, deviation upper limit, deviation upper limit, deviation absolute value lower limit, fault alarm and four standby alarm methods.(Standby alarm mode: when the measured value is in the output interval, when the measured value enters the non-output interval, then the normal alarm)
■Higher degree of standardization, rich functions. Including: input signal fault processing, measurement value clearance, peak, valley value acquisition, 10 section broken line correction and other functions
■Optional transmission, communication

Installation precautions：
（ 1 ）Please avoid the installation in the following places：
1.1：Because of the drastic temperature change, it may be exposed places
1.2：Places where corrosive gases and combustible gases are produced
1.3：Where direct vibration or may impact the product
1.4：Dust, salt, metal powder more places
1.5：Clutter interference, prone to static electricity, magnetic field, noise place
1.6： Air conditioning or heating air flow blowing directly to the place
1.7： A place where the sunlight shines directly
1.8： Due to thermal radiation and other possible thermal accumulation of places
(2) When installing, please consider the following points:
2.1：In order not to hinder heat dissipation, do not block the surroundings of this product, do not block the ventilation openings, and leave sufficient ventilation space.
2.2：Considering wiring and maintenance, please ensure there is more than 50mm of space above and below the instrument.
2.3：Please installing installation directly above the high heat meter (heater, transformer, semiconductor operator, high power resistance).
2.4：If the ambient temperature is above 50℃, please use a forced fan or a cooler, but do not let the cooling air blow directly to the instrument.
2.5：In order to improve noise resistance and safety, please keep away from high pressure machine, power line, power machine for installation.
Ⅵ：Single channel XSEW display controller digit instrument wiring precautions
- In order to avoid the influence of noise interference, please keep the input signal line away from the instrument power line, power power line and load line.
- Ensure that the instrument power supply is not affected by the noise of the power supply when wiring. Where noise is susceptible, use a noise filter.
- Please twist the wire material into a twist shape. The shorter the pitch of the twist, the better the noise defense effect.
- Be sure to install the noise filter on the ground disk surface, and minimize the wiring between the output side of the noise filter and the power terminal.
- Please do not install the fuse, switch, etc. on the output side of the noise filter, otherwise the effect of the filter will be reduced.
- Note: There is no fuse inside this instrument. For fuse-required occasions, please set up separately: recommended fuse specifications:
- Rated voltage 250V, time delay fuse of rated current 1A
- Please use the power supply that meets the power supply specification.
- Please avoid mixing the interference in the measurement circuit
- The measurement circuit is separated from the power cord (power circuit) or the ground circuit.
- For the interference of static electricity, the use of shielding line effect is good.
- To prevent misoperation, please do not attach any wires to the unused terminals.
