Step 3: Select the measurement function and range
To select the measurement function and range:
1. Select the
DISPLAY
key to place it in single-channel-display mode.
2. Select the measurement function by pressing the
MEAS
key.
3. Set the measurement range with the
RANGE
keys, or enable
AUTO
range. When setting the
range, consider the following points:
When measuring the source (such as when sourcing V and measuring V), you cannot select
the measurement range using the RANGE keys. The selected source range determines the
measurement range.
When not measuring the source (such as when sourcing V but measuring I), measurement
range selection can be done manually or automatically. When using manual ranging, use the
lowest possible range for best accuracy. When autorange is enabled, the 2606B
automatically goes to the most sensitive range to make the measurement.
Step 4: Turn the output on
To turn the output on, select the
OUTPUT ON/OFF
switch on the virtual front panel. The OUTPUT
indicator light turns on.
Step 5: Observe readings on the display.
Press the
TRIG
key if necessary to trigger the instrument to begin taking readings. The readings are
on the top line, and source and limit values are on the bottom line.
Step 6: Turn the output off
When finished, turn the output off by pressing the
OUTPUT ON/OFF
switch. The OUTPUT indicator
light turns off.
Remote source-measure commands
Basic source-measurement procedures can also be performed through a remote interface. To do this,
send the appropriate commands. The following table summarizes basic source-measure commands.
See
(on page 5-1) for more information on using these commands.
