User’s Manual
Basic Source-Measure Operation
3-3
Operation overview
Source-measure capabilities
From the front panel, the SourceMeter can be configured to perform the following
operations:
•
Source voltage — Display current and/or voltage measurement
•
Source current — Display voltage and/or current measurement
•
Measure resistance — Display voltage or current component of measurement
•
Measure only (V or I) — Display voltage or current measurement
Voltage and Current
—
Table 3-1
lists the source and measure limits for the voltage and
current functions. Minimum source-measure levels are listed as follows:
V-Source:
±5µV
V-Measure: ±1µV
I-Source:
±50pA (2400 and 2410)
±500pA (2420, 2425, 2430, and 2440)
I-Measure: ±10pA (2400 and 2410)
±100pA (2420, 2425, 2430, and 2440)
Resistance
— The Models 2400 and 2410 can make resistance measurements from
<100
Ω
to >200M
Ω
. The Models 2420, 2425, 2430, and 2440 can make resistance
measurements from <2
Ω
to >20M
Ω
. For the auto ohms measurement method, the
following ranges are available:
2400 and 2410

When using the manual ohms measurement method, you cannot select ohms ranges. The
ohms reading is the mathematical result of V/I.
Measure only (V or I)
— The SourceMeter can be used exclusively as a voltmeter
(V-Meter) or an ammeter (I-Meter). When used as a V-Meter only, the I-Source is set to
output 0A. When used as an I-meter only, the V-Source is set to output 0V.
Range of operation
— The maximum power outputs are summarized as follows:
2400
— 22W (21V at 1.05A or 210V at 105mA)
2410
— 22W (21V at 1.05A or 1100V at 21mA)
2420
— 66W (63V at 1.05A or 21V at 3.15A)
2425 and 2430
— DC Mode: 110W (105V at 1.05A) or 66W (21V at 3.15A)
2430
— Pulse Mode: 1.1kW (105V at 10.5A)
2440
— 66W (42V at 1.05A or 10.5V at 5.25A)
