Accuracy Specications: ± ( % of reading + % of range) [1]

[1] Specications are for 90-minute warm-up and 100NPLC integration time.

For integration time <100NPLC, add the appropriate “RMS Noise Adder”

listed in the following table.

[2] 10% overrange on all ranges except DCV 1000V 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] Specications are for 4–wire resistance measurement or 2–wire

resistance measurement using REL operation. Without REL operation,

add 0.2 Ω additional error in 2-wire resistance measurement.

[7] Accuracy specications 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.

Settling Time Considerations

Reading settling times are affected by source impedance, cable dielectric characteristics and input signal changes. The default

measurement delay is selected to give rst reading right for most measurements.

Measurement Considerations

Telon or other high-impedance, low-dielectric absorption wire insulation is recommended for these measurements.

The default measurement delay is selected to give rst reading right for most measurements. Make sure the RC circuit of input terminal

has been fully settled (about 1s) before accurate measurement.

Applying > 300 Vrms (or > 5Arms) will cause self-heating in signal-conditioning components and these error are included in the

instrument specications. Internal temperature changes due to self-heating may cause additional error on lower ac voltage ranges. The

additional error will be lower than 0.02% of reading and will generally dissipate within a few minutes.

Measuring Characteristics

Accuracy Specications: ±(% of reading)[1][2]

Additional Low Frequency Errors: (% of reading)

[1] Specications are for 90 minutes warm-up, using 1s gate time.

[2] For frequency ≤ 300 kHz, the specication is the 10% to 110% of range of the AC input voltage. For frequency > 300 kHz, the specication is the

20% to 110% of range of the AC input voltage. The maximum input is limited to 750V rms or 8 ×107 Volts-Hz (whichever is less). 200 mV range is

full range input or input that is larger than the full range. For 20mV to 200mV, multiply % of reading error ×10.

[3] Relative to calibration standards.

[6] For continuous current > DC 7A or AC RMS 7A, 30 seconds ON and 30

seconds OFF.

[7] For frequency blow 100 Hz, the specication of slow lter is only for

sinewave input.

[8] Specications are for sinewave input >5% of range. For inputs within 1% to

5% of range, add 0.1% of range additional error. Specications are typical

values for 200uA and 2mA, 2A and 10A ranges when frequency >1kHz.

Measurement Considerations

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

pickup is critical for minimizing measurement errors.

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 accurate measurement.

Temperature

Measurement Considerations

The built-in cold junction temperature tracks the temperature inside the banana jack. The change of the temperature in banana jack

might cause additional error. When using the built-in cold junction compensation, connect the sensor terminal of the thermocouple to

the banana jack and warm it up for more than 3 minutes to minimize the error.
