Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual
Display
This section provides information about the Model 6482 display.
Display format
The Model 6482 display is used primarily to display measured readings and voltage bias source
values. The measurement function readings are displayed on the top line and the voltage bias
values are displayed on the bottom line. You can select channel 1, channel 2, or dual-channel
display with the CHANNEL SELECT and DISPLAY TOGGLE keys; see
below. When in dual-channel display mode, channel 1
measurement function readings (MSR1) are displayed on the left and channel 2 measurement
function values (MSR2) appear on the right.
Measurement reading information can be displayed using either engineering units or scientific
notation in either fixed- or floating-point format. To select the display format, press the
MENU
key,
and then select
GENERAL

NUMBERS
(for more information, see
later in this section).
Engineering units example: 1.234567 µA
Scientific notation example: 1.234567e -6A
Indicators, which are located along the top of the reading/message display, indicate various states
of operation, as covered previously in
DISPLAY CHANNEL SELECT key
The CHANNEL SELECT key toggles between the channel 1 and channel 2 measurements (on the
display’s left side) when the single-channel display mode is selected.
DISPLAY TOGGLE key
The DISPLAY TOGGLE key turns the dual-channel display mode on or off. When the dual-channel
mode is active, the channel 1 measurement function reading (MSR1) appears on the left (I, V/I, I/V,
I
×
V, or MX + B) and the channel 2 measurement function (MSR2) appears on the right of the top
line. The DISPLAY TOGGLE key is also used to select the channel and display statistical data
about readings stored in the data store buffer. These functions are performed from the data store
RECALL mode. See
for data store information.
Status and error messages
Status and error messages are displayed momentarily. During Model 6482 operation and
programming, you will encounter a number of front-panel messages. Typical messages are either
status messages or error messages and are displayed momentarily (see
information).
Disabling the front-panel display
Front-panel display circuitry can be disabled to allow the instrument to operate at a higher speed
(see
). While disabled, the display is frozen with the following message:
FRONT PANEL DISABLED
Press LOCAL to resume.
As reported by the message, all front-panel controls (except LOCAL, TRIG, and OUTPUT ON/
OFF) are disabled.
