| Power frequency mode | Range: 50Hz (40 - 60Hz), 60Hz (50 - 70Hz), 400Hz (390 - 410Hz) (full scale= 20 div), 3 settings Accuracy: ±0.03Hz (exclude 400Hz range), ±0.1Hz (400Hz range) |
| Integration mode | Range: 2k counts/div to 1M counts/div, 6 settings Accuracy: ±range/2000 |
| Duty ratio mode | Range: Between 10Hz to 100kHz (minimum pulse width 2μs), 5%/div (full scale=20 div) Accuracy: ±1% (10Hz to 10kHz), ±4% (10kHz to 100kHz) |
| Pulse width mode | Range: Between 2μs to 2sec, 500μs/div to 100ms/dv (full scale=20 div) Accuracy: ±0.1% f.s. |
| Measurement resolution | 1/2000 of range (Integration mode), 1/500 of range (exclude integration, power frequency mode), 1/100 of range (power frequency mode) |
| Input voltage range and threshold level | ±10V to ±400V, 6 settings, selectable threshold level at each range |
| Other functions | Slope, Level, Hold, Smoothing, Low-pass filter, Switchable DC/AC input coupling, Frequency dividing, Integration over-range keep/return |
