MAINTENANCE
Care must be taken to compress the black square ring
before attempting to twist the housing. Forceful twisting
of the housing can permanently damage the sensor.
Securing the Sensor
In order to compress the black square ring, the sensor
must be secured so that you can apply downward pressure
to compress the ring. This can be done by holding in your
hand, using a vise, or using pliers, as follows.
By Hand—cabled version only
1. Tightly grasp the top cap in one hand.
2. Brace your hand against something such as a
table or the ground. (Do not allow the cable to be
pinched against the brace.)

With Vise—recommended method
Cabled Sensor
1. If possible, use a set of soft jaws as shown to
prevent marring the surfaces of the top cap
assembly.
2. Place the sensor in a vise clamping gently on the
swaged area. You do not need to clamp the vise
very hard.

Cabled Sensor—gripping on swage
Cableless Sensor
1. If possible, use a set of soft jaws as shown to
prevent marring the surfaces of the top cap
assembly.
2. Remove the cableless top cap.
3. Place the sensor in a vise clamping gently on the
knurled area. You do not need to clamp the vise
very hard.

Cableless Sensor—gripping on knurled area
With Pliers or Vise Grips—good for field use
Cabled Sensor
1. Grasp the pliers on the swaged area (do not grab
the knurled diameter).
2. Find a hard edge and place the tips or side of the
jaws of the pliers onto this edge as shown. This
will allow you to press down with your weight to
compress the square ring.

Cableless Sensor
1. Leave the cableless cap on in order to protect the
pins inside.
2. Grasp the pliers on the knurled area tightly being
careful to avoid grabbing the knurled cap.
3. Find a hard surface and place the cableless cap
down onto it. This will allow you to press down with
your weight to compress the square ring.
