Adjustment step

\
\

One Incentive regulation

\
\

After connecting the sensor and power supply，adjustRV5Adjustable excitation voltage provided by transmitter to sensor，May pass+EXCand-EXCmeasure。

\
\

Two Zero adjustment

\
\

1：Voltage adjustment After the motivation is adjusted，First place the sensor at no load，Adjust voltage zero potentiometer（RV1）,Use a multimeter to measure the outputVOVoltage，Make the indication as close as possible to the zero point indication,If you can't adjust to zero, you can try toK2Allocate toON。

\
\

2：Current adjustment After the motivation is adjusted，First place the sensor at no load，Adjust current zero potentiometer（RV3）,Measure the output terminal with the current gear of the multimeterIOElectric current，Keep the indication as close as possible4mA,If it can not be adjusted4mATry to putK2Allocate toON。

\
\

Three Full scale adjustment

\
\

1：Full voltage regulation Load the sensor with a certain weight value(Recommended scope：80%~100%FS)，Calculate the output voltage according to the ratio between the loaded weight and the maximum weighing value，Monitor output with digital multimeterVOVoltage，Rotary voltage full potentiometer（RV2）Adjust full output。

\
\

2：Full current regulation Load the sensor with a certain weight value(Recommended scope：80%~100%FS)，Calculate the output current according to the ratio between the loaded weight and the maximum weighing value，Monitor the output with the current gear of the digital multimeter，Rotating current full potentiometer（RV4）Adjust full output，Keep it as close as possible20mA。

\
\

Re examination

\
\

Leave the sensor empty，Measuring zero point output；Load a certain weight value，Measure whether the output voltage or current meet the expected value。If not，Please adjust again。
