Section 1: Getting Started Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual
• EDIT or increments or decrements the source value. Note that pressing either of these
keys will automatically enable the source edit mode.
• RANGE or selects the voltage bias source range (10 V or 30 V).
• Numeric keys (0 through 9) allow you to directly enter source values.
• EXIT exits the edit mode without waiting for the time-out period.
The basic procedure for editing source values is outlined below. See Section 3 , “Basic
measurement procedure,” for more details.
1. Press the SRC1 or SRC2 key so that the blinking cursor is in either the channel 1 (Src1) or
channel 2 (Src2) source display field to be edited.
2. You can use the RANGE and keys to select the source range. Use the lowest range
possible for best accuracy.
3. To increment or decrement the displayed source value, use the EDIT and keys to place the
blinking cursor on the digit to be changed, then increment or decrement the value with the EDIT
and keys. Note that the source value will be updated immediately; you do not need to
press the ENTER key to complete the process.
4. To enter the source value directly, enter in the value with the numeric keys while the cursor is
blinking. The source value will be updated immediately.
Configuration menus
There are a number of configuration menus that can be accessed by pressing the CONFIG key
followed by the appropriate function or mode key. For example, you can configure the
measurement functions by pressing the
CONFIG key, and then pressing the MSR1 (channel 1) or
MSR2 (channel 2) key. Configuration menus, which are summarized in Table 1-4 through
Table 1-10 , are available for the following operating modes:
• Measurement functions (MSR1, MSR2, RATIO, DELTA); see Table 1-4 .
• Voltage source (SRC1 and SRC2); see Table 1-5 .
• REL, FILTER, and RANGE; see Table 1-6 .
• LIMIT; see Table 1-7 .
• TRIG; see Table 1-8 .
• SWEEP, DIGITS, SPEED, and STORE; see Table 1-9 .
• ON/OFF OUTPUT and DISPLAY TOGGLE; see Table 1-10 .
These configuration menus are covered in detail in the applicable sections of this manual.
