Using instrument

Power on

With instrument in its o󰀨 state, momentarily depress the ON/OFF button on the front panel to turn the

instrument on.

Enter the passcode (if Require passcode option is enabled in the Set Options menu) and click the

Acknowledge... button in the Splash screen signifying that the warning message has been read (refer to

Safety section).

At the Main screen the Welcome prompt will be displayed along with information such as the date and time

when the instrument was last used, and a prompt to replace the clock battery if it is found to be low (refer to

Power o󰀨

With instrument in its on state, momentarily depress the ON/OFF button on the front panel to put the

instrument into its powering down sequence, during which it will perform an orderly shutdown and save

various user congurations settings, and show the message “Shutting Down, please wait...”.

In the event of an abnormal lock-up of the instrument or its rmware, the unit can be forced into

a hardware power down by depressing the ON/OFF button and holding it depressed until the unit

switches o󰀨 after a few seconds.

are loaded. It may also be forced to enter this mode if the user depresses the TEST button on the front
