2-10 Measurement Options Model 6517A Getting Started Manual

Conﬁguring V-Source

Perform the following steps to conﬁgure the V-Source:

1. Press the CONFIG key and one of the VOLTAGE SOURCE keys (OPER, , or )

to display the following conﬁguration menu:

RANGE: Select the 100V range or 1000V range.

V-LIMIT: Control (on/off) and set a voltage limit (absolute value).

RESISTIVE LIMIT: Control (on/off) the resistive (1MΩ) current limit.

METER CONNECT: Control (on/off) the internal connection between V-Source

LO and ammeter LO.

2. Use the menu items to conﬁgure the V-Source. A menu item is selected by placing

the cursor (using the

 and  keys) on it and pressing ENTER. Options for a menu

item are selected in the same way. Parameter values are changed using the cursor

keys and the RANGE keys, and then pressing ENTER. See “Menus” previously in

this section if you need more information to navigate through the menu structure.

3. Use the EXIT key to back out of the menu structure.

Relative

Rel subtracts a reference value from actual readings. When rel is enabled, the instrument

uses the present reading as a relative value. Subsequent readings will be the difference

between the actual input value and the rel value.

Actual Input – Reference = Displayed Reading

The rel (relative) operation is enabled by pressing the REL key (REL annunciator turns

on). Pressing REL a second time disables rel. You can also enter and enable a rel value

from the CONFIG-REL display.

A rel value can be established for each measurement function. The state and value of rel

for each measurement function are saved when changing functions. Once a rel value is

established for a measurement function, the value is the same for all ranges.

Conﬁguring rel

To check or change a rel value for a measurement function, perform the following steps:

1. Select the desired measurement function.

2. Press the CONFIG key and then the REL key to display the present rel value.

3. Use the cursor keys (

 and ) and the RANGE keys to change the rel value and

press ENTER. The instrument will return to the normal display state with rel

enabled.
