power.
• Use the DISPLAY SELECT push button to display the setpoint value. The forward
power and setpoint values should agree with each other within the allowable regula-
tion tolerance of the generator (1%).
• If the displayed forward power and setpoint values are in agreement, continue to
increase the setpoint value slowly.
• Stop periodically to verify that the forward power and setpoint values are continuing
to track together. Also verify that the reflected power readings remain near zero (this
assumes that the test load is purely resistive).
• Continue this process until 5000 W is reached (Setpoint signal equals 10 V). At no
point during the test should the ALARM indicator light. If, for any reason, the gener-
ator does not perform properly, shut off the circuit breaker and refer to the trouble-
shooting section in this manual for further guidance.
• Inactivate the RF Pwr On signal at the User port and verify that the RF ON indicator
extinguishes. The forward and reflected power readings on the display go to zero,
regardless of the value of the Setpoint signal.
• Move the circuit breaker to the off (0) position to complete this initial test.
• Turn off the cooling water if no further testing is required.

The display is scaled by a factor of 1000, (200 W is displayed as ".20").
