| Measurement resolution | 1/100 of measurement range (using 12-bit A/D conversion and when installed in 8847) |
| Highest sampling rate | 1 MS/s (simultaneous sampling across 2 channels) |
| Measurement accuracy | ±0.5 % of full scale (with filter 5 Hz, zero position accuracy included) |
| RMS measurement | RMS amplitude accuracy: ±1 % of full scale (DC, 30 Hz to 1 kHz), ±3 % of full scale (1 kHz to 100 kHz), Response time: SLOW 5 s (rise time from 0 to 90% of full scale), MID 800 ms (rise time from 0 to 90% of full scale), FAST 100 ms (rise time from 0 to 90% of full scale), Crest factor: 2 |
| Frequency characteristics | DC to 400 kHz -3 dB, with AC coupling: 7 Hz to 400 kHz -3dB |
| Input coupling | AC/DC/GND |
| Max. allowable input | 400 V DC (the maximum voltage that can be applied across input pins without damage) |
