•Press the following keys:

[ CHANNEL 1 ]

[ CHANNEL 1 RANGE ]

The range should be set to 5 dBVrms.

•Press [ Rtn ].

•Repeat steps 5 and 6 for each channel.

•If only one channel, or channel 1 and 3, or channel 2 and 4 are failing, the A1/A2 Input assembly is probably faulty.

In the two channel analyzer, the A1 Input assembly provides the circuits for channel 1 and 2. In the four channel analyzer, the A2 Input assembly in the lower slot provides the circuits for channel 1 and 3, and the A2 Input assembly in the upper slot provides the circuits for channel 2 and 4.

•If all channels are failing, the A5 Analog assembly is probably faulty.
