Rack Mounting
The OMM-6810B may be rack mounted by installing a rack mount flange on each
side of the enclosure. Detailed installation instructions are included with the rack
mount kit. Refer to Chapter 1 for applicable rack mount accessory part numbers.
Power-Up Sequence
Connect the instrument to an AC power source. Press the POWER switch to
supply power to the device and start the power-up sequence.
The power-up sequence takes about six seconds. Initially, all LEDs and
enunciators are illuminated and the seven-segment displays denote "8". Then, all
LEDs and the displays are turned off while the microprocessor executes a device
self-test. Should the self test fail, error message E-720 is displayed. The device
then loads personality and calibration data from the measurement head. The
OMH model number is shown on the left display and the firmware version is
shown on the right display. If an error occurs while loading data, message E-711
is displayed. If a incompatible head is connected, E-713 is displayed. If a
measurement head is not connected both displays show "------" until a head is
attached. Refer Appendix A for a detailed explanation of error messages.
