Before apply AC power to the UDR Simulator, read
the operation section of the 955A Standard Manual
located in Appendix D.
1. After the equipment has been installed and all pre-power tests have, apply power by depressing
and releasing the front panel AC power switch on the UDR Simulator and energize the signal
isolator by applying AC power.
2. Enter or verify the setpoints listed in the Table below and record. Setpoints are entered by placing
the rotary function switch in the desired number position corresponding to the setpoint and
depressing the “ENTER” pushbutton to display the current value. If the setpoint value is correct,
depress the “ENTER” pushbutton a second time to accept the value, then move the rotary function
switch to the next desired position. If the setpoint value is to be change, use the “VAUE” and
“DIGIT” pushbuttons to edit the value, then depress “ENTER” to accept. Note that the “VALUE”
pushbutton is used to alter the “E” or exponent to “-“ or negative when a value less than one is
required.
