If a problem is encountered, the most probable error message is:
E7XXXX "BEL"
Calibration signal out-of-range, unit will revert to last calibration status
For more detailed testing of the unit, such as frequency response, etc., an external electrical input can be used or the
transducers can be placed on a transducer calibration system (shaker, etc.) for providing a calibrated input at any
frequency of interest.

STORE AND RECALL SETUPS
Up to 10 separate setups can be stored and recalled by command over the RS-232 bus.
A.
STORE AND RECALL SETUP
The 6634C permits storing up to 10 setups in non-volatile memory for rapid and accurate test preparation. To
store the current setup for later recall, send the following command over the RS-232 bus:
PnXXXX ;
Store setup n, where n = 0 to 9
To recall a stored setup and implement that setup in the 6634C, send the following command over the RS-232
bus:
QnXXXX ;
Recall setup n, where n = 0 to 9
If an attempt is made to recall a setup, which was not previously stored, the following response is sent from the
6634C (if unit is set to Listener/ Talker mode):
E1XXXX "BEL"
Setup not previously stored
8.
STATUS
Status is sent to the controller in response to specified status requests.
A.
SETUP STATUS
As described in Section 4.2 through 4.5, the setup status of the 6634C can be determined by replacing Byte 1 in a
command with a question mark. For example, to determine the Input Type setting of the unit, send [T?XXXX ;]
and the unit will respond with the question mark replaced by the appropriate Input Type number and the
semicolon replaced by "ACK". For example:
Query:
T?XXXX ;
Produces response:
T1XXXX "ACK" when unit setup for velocity coil input
B.
ALARM STATUS
The alarm status of the 6634C can be determined by sending the following query (after selecting the specific
6634C unit as Listener/Talker using the InnXXX; command):
