Step 4: Turn Output On - Keithley SourceMeter 2400 User Manual

2400 Series SourceMeter User's Manual
NOTE 2400 — With the 200V V-Source range selected, the highest current measure-
ment range is 100mA. With the 1A I-Source range selected, the highest voltage
measurement range is 20V.
2410 — With the 1kV V-Source range selected, the highest current measurement
range is 20mA. With the 1A or 100mA I-Source range selected, the highest volt-
age measurement range is 20V.
2420 — With the 60V V-Source range selected, the highest current measurement
range is 1A. With the 3A I-Source range selected, the highest voltage measure-
ment range is 20V.
2425 and 2430 (DC Mode) — With the 100V V-Source range selected, the high-
est current measurement range is 1A. With the 3A I-Source range selected, the
highest voltage measurement range is 20V.
2440 — With the 40V V-Source range selected, the highest current measurement
range is 1.05A. With the 5A I-Source range selected, the highest voltage mea-
surement range is 10.5V.
Measurement range is also limited by the compliance setting. For example, if
voltage compliance is 1V (2V compliance range), the highest voltage measure-
ment range that can be selected is 2V.

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 compli-
ance 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.
The SourceMeter can be taken out of compliance by going into the edit mode and decreas-
ing the source value or increasing the compliance value. Note that increasing the compli-
ance limit may compromise protection for the DUT. If in range compliance, selecting a
higher measurement range may take the SourceMeter out of compliance.
