Arbiter Systems 1040C - Hand Held Unit and GPIB Operation

2-20
2.6 Hand Held Unit
The Hand Held Unit, when connected to the Remote connector on the PMC Front Panel, has
controls, which duplicate controls on the PMC Front Panel. The Hand Held Unit has a 4 digit
display, lighted pushbuttons and a MODIFY UP/DOWN Rocker Switch which duplicate the
function of the numeric portion of the PMC display, the keys and LED indicators, and the
MODIFY UP/DOWN keys, respectively.
In addition to displaying numeric values, the Hand Held Unit display uses error codes, as shown in
Table 2.3, to indicate errors that are displayed in message form on the PMC display. The Hand
Held Unit keys can be used interchangeably with the corresponding PMC front panel keys.
Once an output function is set up on the PMC, the Hand Held Unit may be used to alter the output;
i.e. MODIFY, DEV (%), NORMAL, OPERATE or STBY. The Hand Held Unit also has
pushbuttons for the STORE and RECALL functions.
