Calibration (Adjustable Models ONLY)
Field adjustable models have a set point adjustment under the removable weathertight cap.
It is not necessary to disconnect the electrical power, since the electrical switching element
is inside the hermetically sealed, explosion proof capsule, thereby maintaining explosion
proof integrity.

Remove knurled weathertight cap.

Use 3/32” hex (Allen type) wrench to turn adjusting screw to achieve desired set point.
Turn adjusting screw clockwise (in) to increase set point; turn adjusting screw
counterclockwise (out) to decrease set point.
Units in hazardous locations prior to removal from service, make sure that the
work area is declassifi ed. Failure to do so could result in severe personal injury
or substantial property damage.
SOR discourages fi eld modifi cations, change-out of wetted parts or repair. It is
recommended that products be returned to SOR for inspection and necessary
repair work. Contact the factory or the SOR representative in your area for a
Returned Goods Authorization number. Any fi eld work should be performed by
qualifi ed instrument technician with formal SOR procedures.
Use an external pressure measuring device to accurately calibrate set points.

After the set point has been calibrated, replace the weathertight sealing cap tightly to
ensure the weathertight integrity of the device.
If adjusting screw is turned counterclockwise too far, it can cause the guide disc
to slide down. The unit will then be inoperable.
