Settling Considerations
Default delays are selected to give first reading right for most measurements. The input blocking RC
time constant must be allowed to fully settle before the most accurate measurements are possible

10 Hz to 300 kHz
Error
(24 hour % of range + % of reading)/5
- Sinewave input only using slow filter.
- Within 10 minutes and ±0.5 °C.
- Within ±10% of initial voltage and ±1% of initial frequency.
- Following a 2–hour warm–up.
- Fixed range between 10% and 100% of full scale (and <120 V).
- Measurements are made using accepted metrology practices
AC–coupled True RMS. Measures the AC component of the input.
Digital sampling with anti–alias filter.
70 dB For 1 k unbalanced in LO lead and <60 Hz, ±500 V peak maximum.
400 Vdc, 1100 Vpeak
1 M ± 2%, in parallel with <150 pF
750 V rms all ranges
Directly coupled to the fuse and shunt.
AC–coupled True RMS measurement (measure the AC component only).
Digital sampling with anti–alias filter.
The peak value of the DC + AC current must be <300% of range.
The RMS current <3 A including the DC current content.
0.1 for 1A, 3A
2 for 10 mA 100 mA
200 for 100 µA, 1 mA
Externally accessible 3A, 250 V fuse
For <10:1 errors included.
Limited by peak input and 300 kHz bandwidth.
300% of Range. Limited by maximum input
Will select higher range if peak input overload is detected during
auto range. Overload is reported in manual ranging.
