Product Description

The adjustment of the Set Point
   1. Link the multimeter with the cable leads of the product.
   2. Screw the bolt off the top of shell.
   3. Add pressure to *5Mpa, the value can be read from the standard menometer.
   6. Tighten the locknut.
Example: choose pressure range 2.4 ~*4Mpa switch, a contact signal is required to be generated
when pressure falls to *5Mpa( the Decreasing Set Point). The steps listed as the following:
  Before setting, please screw the product into the threaded connection of test desk, simulate the real working
condition to exert pressure on to the product 2 minutes.
   4. Use 3mm socket head screw spanner, clockwise rotate the socket head screw slot, the Set Point will become
biger, until the contact points switches at *5Mpa.
   5. Regulate the pressure of the testing desk to be arround at *5Mpa, to check if it switches at the *5Mpa when
pressure falls. This is just the Decreasing Set Point. The correspodent Increasing Set Point is between
*6.9Mpa~*8Mpa.
