Description
Key Features
• Fluctuating of power line frequency measurement for commercial power (direct input up to 200 V class line)
• Pulse counting for the encoder
• For the motor rotation, pules integration, duty ratio, and pulse width measurement
• Isolated input, up to 300 V AC/DC from the earth
Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)
| Measurement functions | Number of channels: 2, for voltage input based frequency measurement, rotation, power frequency, integration, pulse duty ratio, pulse width |
|---|---|
| Input connectors | Isolated BNC connector (input impedance 1 MΩ, input capacitance 30 pF),Max. rated voltage to earth: 300 V AC, DC (with input isolated from the unit, the maximum voltage that can be applied between input channel and chassis and between input channels without damage) |
| Frequency mode | Range: Between DC to 100kHz (minimum pulse width 2μs), 1Hz/div to 5kHz/div (full scale= 20 div), 8 settingsAccuracy: ±0.1% f.s. (exclude 5kHz/div), ±0.7% f.s. (at 5kHz/div) |
