Specifi cation Condition
The “supplemental” information and
“typical” entries in the following speci-
fi cations are not warranted, but provide
useful information about the functions and
performance of the instruments.
The measurement and output accuracy are
specifi ed at the rear panel connector termi-
nals when referenced to the Zero Check
terminal under the following conditions:
1. 23 °C ±5 °C (double between 5 °C to
18 °C, and 28 °C to 40 °C if not noted
otherwise)
2. After 40 minutes warm-up
3. Ambient temperature change less than
±1 °C after auto calibration execution.
4. Integration time: medium or long
5. Filter: ON (for SMUs)
6. Kelvin connection (for HRSMU, HPSMU,
and GNDU)
7. Calibration period: 1 year

1 The accuracy is applicable when offset cancellation has been performed.
2 The offset current specifi cation is multiplied by one of the following factors
depending upon the ambient temperature and humidity (RH = Relative Humidity):
Humidity % RH
Temperature 5 - 60 60 - 80
5 °C to 18 °C ×2 ×2
18 °C to 28 °C ×1 ×2
28 °C to 40 °C ×2 ×5
3 100 V (Iout≤20 mA), 40 V (20 mA<Iout≤50 mA), 20 V (50 mA<Iout≤100 mA)
Vout is the output voltage in volts. Iout is the output current in amps.
For example, accuracy specifi cations are given as ±% of set/measured
value (0.04%) plus offset value (200 nA+1 nA×Vout) for the 1 mA range.
The offset value consists of a fi xed part determined by the set/measure-
ment range and a proportional part that is multiplied by Vout or Vout/100.

The SMU can limit output voltage or
current to prevent damaging the device
under test.
