Step 3: Select the measurement function and range
To select measurement function and range:
1. If the instrument has two channels (2602B, 2604B, 2612B, 2614B, 2634B, or 2636B), press the
DISPLAY key to place it in single-channel-display mode (if not already). Otherwise, go to the next
step.
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), you can select
the measurement range selection manually or the instrument can set it automatically. When
using manual ranging, use the lowest possible range for best accuracy. When autorange is
enabled, the 2600B automatically goes to the most sensitive range to make
the measurement.
Step 4: Turn the output on
Turn on the output by pressing the OUTPUT ON/OFF switch. 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 making 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.
