9.10.Cleaning Exterior Surfaces of the M465L

If necessary, the front panel mask and keyboard of the M465L can be cleaned with a damp cloth. Do not attempt to clean any of the other surfaces of the instrument. Do not submerge any part of the instrument in water or cleaning solution.

9.11.Boot Loader Operation

The main function of a boot loader is to load or update the firmware to the microcontroller on the Printed Circuit Board (PCB) of an instrument. There are two types of boot loader setup: hardware and software, described in the following sections.

NOTE

When an external MODBUS host device is attempting to communicate with the instrument over the serial or Ethernet port while the instrument is starting up, the instrument may halt. In order to prevent the problem from occurring, ensure that there are no devices attempting communication with the instrument during start-up. Once the sign-on message is displayed on the front panel, it is safe to begin communications.
