7. Connections 

 
Good  connections  require  a  skilled  operator.  The  most  common  cause  of  measurement  error  is 
bad connections. The following procedures illustrate how to make good connections. 
 

Making a Connection 

 

The  calibration  kit  comes  with  a  so-called  combi-wrench  which  is  a  useful  tool  to  make 
connections. This wrench is made of plastic and helps you to hold the device body and prevent it 
from rotating while making a connection. 
 

Preliminary Connection 

 

1.  Ground  yourself  and  all  devices.  Always  wear  a  grounded  wrist  strap  and  work  on  a 

grounded, conductive table mat. 

2.  Visually inspect the connectors. 
3.  If necessary, clean the connectors. Refer to 4.1 Connector Care. 
4.  Use a connector gage to verify that all centre conductors are within the observed pin depth 

values in Table 2-2. Refer to 4.2 Interface Dimensions and Gaging. 

5.  Carefully align the connectors. The male connector centre pin must slip concentrically into 

the contact finger of the female connector. 

6.  Push the connectors straight together and tighten the connector nut finger tight. 

 
CAUTION: Do not turn the device body. Only turn the connector nut. Damage to the centre 
conductor can occur if the device body is twisted. 
 
Do not twist or screw the connectors together. As the centre conductors mate, there is 
usually a slight resistance. 

 

7.  The preliminary connection is tight enough when the mating plane surfaces make uniform, 

light  contact.  Do  not  overtighten  this  connection.  A  connection  in  which  the  outer 
conductors  make  gentle  contact  at  all  points  on  both  mating  surfaces  is  sufficient.  Very 
light finger pressure is enough to accomplish this. 

 

8.  Make  sure  the  connectors  are  properly  supported.  Relieve  any  side  pressure  on  the 

connection from long or heavy devices or cables. 

 

9.  Final Connection Using a Torque Wrench 

 

10. Use a torque wrench to make a final connection. Table 4-2 provides information about the 

torque wrench recommended for use with the calibration kit. A torque wrench is included in 
the calibration kit.
