Open the HSM connector, unscrew the stainless steel tube, you can see the zero and full-range resistors, external standard power supply and ammeter (0.2 or more), you can adjust, the steps are as follows:
1. When the transmitter is not pressurized, adjust the zero resistor to make the output current 4mA;
2. The transmitter is pressurized to full scale, and the full-range resistor is adjusted to make the output current 20mA;
3. Repeat the above steps two or three times until the signal is normal;
4. After adjustment, tighten the protective cover.
5. All products are supplied with instructions for use and certificate of conformity, including product number, technical parameters, date of manufacture, etc. Please check carefully to avoid mistakes.
6. Do not use a hard object to directly squeeze the transmitter diaphragm to avoid damage to the transmitter.
7. When installing, check whether the field interface is consistent with the product interface according to the product connection mode and thread type. When connecting, it should be tightened slowly. The torque cannot be directly added to the transmitter housing. It can only be added to the pressure interface. On the six sides.
8. When connecting the power supply, it should be connected in strict accordance with the wiring instructions.
9. The transmitter overload pressure should not exceed 150% of the range.
10. If an abnormality is found during use, turn off the power, stop using it, check it, or contact the technical department directly.
