1.15 Service Pendant
The service pendant is used to set and display parameters for the 947/948/960 Leak
Detector. It is a handheld terminal with a 40-key keypad and a 20 character x 4 line backlit
LCD display (see Figure 1-13). The service pendant is stored in the turret and connects to
the 947/948/960 using a six-foot cable that connects to an RS-232 serial port (J1, a 9-pin
D sub connector) located inside the lockable turret.
The service pendant is used to monitor and set up:
❑
Reject set point
❑
Crossover pressures
❑
Auto sequence parameters
❑
Ion Source parameters
❑
System setup parameters (such as the value of the calibrated leak)
Refer to “Using the Pendant for Parameter Setup” on page 3-35 for further information on
the operation of the service pendant.
