REM Annunciator

Gand Dcan now be used to change the monitored channel. All other front panel buttons are locked out; a long beep results from their use. Press both Fand Bagain to deactivate the Monitor Only function and return the instrument to normal front panel button operation (regular Monitor Function on.)

Computer Interface-Initiated Lockouts

Front Panel lockout can also be specified over the Computer Interface with the following commands.

∙REMS (RS-232 only): four front panel buttons remain active (Q, G, K, and R).

∙RWLS (RS-232 only): only the Rbutton remains active.

∙LOCK 1 J, H, G, and Dcan now be used to view the various elements of the Review Array. All other front panel buttons are locked out, yielding a long beep when pressed. Press both Fand Bagain to deactivate the Review Only function and return the instrument to normal front panel button operation (regular Review Array display.)

∙LOCK 2 Gand Hcan now be used to change the monitored channel. All other front panel buttons are locked out; a long beep results from their use.

Refer to Chapter 4 for additional information on these commands.

REM Annunciator

The front panel REM annunciator identifies the status of both computer interface control and front panel lockout. REM may be lit due to actions taken from the computer interface or the front panel; it can be off, dim, or bright as shown in Table 3-19.

Calibration

Refer to Chapter 6 (Maintenance) of this manual for a general discussion of instrument calibration. Refer to the Hydra Series II Service Manual (P/N 688868) for complete calibration procedures.

The CAL ENABLE control point is located in the lower-right corner of the display. When the instrument is correctly calibrated, this control should be covered with a calibration decal; removing the decal voids assurance of correct calibration.

Note

Do not press CAL ENABLE unless you have a copy of the Service Manual and intend to calibrate the instrument. If you have accidentally activated Calibration and wish to exit immediately, press CAL ENABLE (until CAL disappears from the display) or turn power OFF.
