Remarks:
SDM3065X Datasheet3[1] Specifications are for 90-minute warm-up and 100NPLC integration time. For integration time <100NPLC, add theappropriate “RMS Noise Adder” listed in the following table.
[2] 10% over range on all ranges except DCV 1000 V and DCI 10A range.
[3] Relative to calibration standards[4] For each additional volt over ± 500 V, add 0.03mV error.
[5] For continuous current > 7A DC or 7A AC RMS, 30 seconds ON and 30 seconds OFF[6] Specifications are for 4–wire resistance measurement or 2–wire resistance measurement using REL operation.
Without REL operation, add 0.2Ω additional error in 2-wire resistance measurement.
[7] Accuracy specifications for the voltage measured at the input terminal only. 1 mA test current is typical. Variation in
the current source will create some variation in the voltage drop across a diode junction. Adjustable voltage range :0~ 4V

Remarks:[1] Typical value. Resolution is defined as the typical 20V range RMS noise.
[2] Normal mode rejection ratio for power-line frequency ± 0.1%. For power-line frequency ± 1%, subtract 20 dB . For ±
3% , subtract 30dB.
[3] Maximum rate for DCV, DCI, 2-wire resistance and 4-wire resistance functions.
[4] The basic DC accuracy specifications include RMS noise at 100 NPLC. For <100 NPLC, add “RMS Noise Adder” tothe basic DC accuracy specifications.
[5] When Power Supply of frequency is 60Hz, the cycles is 0.006, 0.06, 0.6, 1, 10, 100 NPLC.

The default measurement delay is selected to give first reading correctly for most measurements.
Make sure the RC circuit of input terminal has been fully settled (about 1s) before reading theaccurate measurement.
Applying >300 Vrms (or > 5Arms) will cause self-heating in signal-conditioning components andthese errors are included in the instrument specifications. Internal temperature changes due to selfheating may cause additional errors on lower AC voltage ranges. The additional error will be lower
than 0.02% of reading and will generally dissipate within a few minutes

MeasureConsiderations

All frequency counters are susceptible to error when measuring lowvoltage, low–frequency signals.
Shielding inputs from external noise is recommended

Settling
Time Considerations

Errors will occur when attempting to measure the frequency or period of
an input following a dc offset voltage change. Make sure the RC circuit of
input terminal has been fully settled (about 1s) before reading the accurate
measurement

Capacitance Measurement
Measurement Method

Apply constant current into the capacitance, and measure the voltagechanging rate.

Connection Type2-wireInput Protection

1000 V on all ranges

Measurement
considerations

Since small capacitance measurements are susceptible to the external
noise, shielding inputs from external noise pickup is critical for minimizing
measurement errors

Temperature Measurement
Measurement Method

Support for TC and RTD types of sensor

Measurement
considerations

The built-in cold junction temperature tracks the temperature inside thebanana jack. The change of the temperature in banana jack may cause
additional error. When using the builtin cold junction compensation,connect the sensor terminal of the thermocouple to the banana jack andallow it warm up for more than 3 minutes to minimize the error.

After more than a decade of continuous development, SIGLENT has extended
its product line to include digital
oscilloscopes,

function/arbitrary

oscilloscopes, isolated handheld

waveform

generators,

RF/MWsignalgenerators, spectrum analyzers, vector network analyzers, digital multimeters,
DC power supplies, electronic loads and other general purpose test
