6-5

[1] Specifications are for 30 minute warm–up, “slow” measurement rate and 18℃ - 28℃

calibration temperature.

[2] 20% over range on all ranges, except DCV 1000V, ACV 750V, DCI and ACI 10A range.

[3] Specifications are for sine wave input >5% of range. 750V range is limited to 8x10

Volt-Hz.

For inputs from 1% to 5% of range and <50 kHz, add 0.1% of range additional error. For 50

kHz to 100 kHz, add 0.13% of range.

[4] Specifications are for sine wave input >5% of range. Add 0.1% of the range for the sine

wave input is 1%~5% of the range.

[5] For continuous current which is higher than DC 7A or AC RMS 7A, disconnecting for 30s after

30s connection.

[6] For frequency <100 kHz. Please refer to the “

Crest Factor Errors (non-sinusoidal inputs)

”

section described on Page 5-3 for bandwidth error of other frequency.

True RMS AC Voltage

Measurement Method: AC coupled true-RMS-measure, the DC component of input with up to

1000V on any range.

Crest factor: Crest factor on full range ≤ 3

Input Impedance: 1MΩ ± 2% in parallel with 100pF on any ranges

Input Protection: 750Vrms on all ranges

AC filter bandwidth: 20Hz~100kHz

CMRR (common mode rejection ratio): 60dB (For the 1kΩ unbalanced resistance in LO lead and

<60Hz, maximum ±500VDC).

True RMS AC Current

Measurement Method: DC coupled to the fuse and shunt. AC coupled true RMS measurement

(measures the ac component only)

Crest factor: Crest factor on full range ≤ 3

Max. Input: The DC + AC current peak value <300% of the range. The RMS

current including DC current is <10A.

Shunt Resistor: 0.01Ω for 2A, 10A

1Ω for 20mA, 200mA

Input Protection: Externally accessible 10A, 250V fast-melt fuse

Internal 12A, 250V slow-melt fuse

Setting time attentions:

Make sure the RC circuit of input terminal has been completely stable (up to 1s) before accurate

measurement.

Input >300Vrms (or >5Arms) will cause the self heating of the signal conditioning component to
