Connector Tightening
Damage to a calibration standard or attaching connector can occur if the device is turned instead of the
connector's coupling nut. ALWAYS turn the coupling nut when making connections. Never turn or spin the
connectors.
Always use a torque wrench (Pasternack model PE5019-8) to final-tighten all connections. This will ensure
calibration accuracy and measurement repeatability.
When making connections, an open-end wrench is recommended to hold the body of one device stationary
while torquing the nut on the other device or cable. This open-end wrench is supplied with the calibration
kit for this purpose.
Using the torque wrench:
Hand-tighten the connection being torqued by holding the calibration device steady and turning only the
coupling nut.
•
Hold the torque wrench with your thumb and index finger, behind the groove in the handle (See
Figure 1.).
•
Tighten the connection until the ball in the handle crests on the cam (as the handle begins to break
over). Do not "fully break" the handle of the torque wrench to reach the specified torque.
•
Reverse the previous procedure to disconnect.
Torque wrench handle will break over when preset torque is achieved.
Take note of the wrench bit orientation relative to the direction of motion/rotation.
