have to be on the polarity sign of the value to change polarity. If the
MENU key is pressed, the Source Value will be clear to 0V or 0A.
4. To edit the other field, press EDIT to select it, and repeat steps 1 and 2.
5. When finished editing the source and compliance values, press ENTER or
wait six seconds to exit from the edit mode.
NOTE When a compliance limit value is entered, the SourceMeter automatically
goes to the lowest (most sensitive) compliance range that will accommo
-
date that value.
For the Models 2400, 2400-LV, 2401, and 2410, the lowest compliance
levels that can be set are 0.00100µA (1nA) and 000.200mV (200µV). For
the Models 2420, 2425, 2430, and 2440, the levels are 00.0100µA
(10nA) and 000.200mV (200µV).
Step 3: Select measurement function and range.
Select the desired measurement function by pressing MEAS V (voltage) or MEAS
I (current).
When measuring the source (i.e., Source V Measure V), you cannot select the
range using the measurement RANGE keys. The selected source range deter-
mines the measurement range.
When not measuring the source (i.e., Source V Measure I), measurement range
selection can be done manually or automatically. When using manual ranging,
use the lowest possible range for best accuracy. In autorange, the SourceMeter
automatically goes to the most sensitive range to make the measurement.
Step 4: Turn output on.
Turn the output on by pressing the ON/OFF OUTPUT key. The OUTPUT indicator
will turn on to indicate the output is on.
Step 5: Observe readings on the display.
The SourceMeter is in compliance if the “Cmpl” label or the units label (i.e. “mA”)
for the displayed compliance setting is flashing. If the “Cmpl” label is flashing, real
compliance has occurred. The output is clamped at the displayed compliance
value. If the units label is flashing, range compliance has occurred. The output is
clamped at the maximum compliance value for the present fixed measurement
range. For example, if presently on the 2V measurement range, a flashing units
label for the voltage compliance value indicates that the output is clamped at 2.1V.
Step 6: Turn output off.
When finished, turn the output off by pressing the ON/OFF OUTPUT key. The
OUTPUT indicator light will turn off.
