Detailed disturbance analysis: – Perform high-speed transient analysis and uncover root cause of equipment malfunction for later mitigation and predictive maintenance. The fast transient option, with its 6000 V measurement range, allows capture of very short impulses such as lightning strikes.
Class-A quality-of-service compliance: – Validate incoming power quality at the service entrance. Thanks to Class A compliance, the Fluke 1760 allows undisputable verification.
Event correlation at multiple locations: – Utilizing GPS time synchronization, users can quickly detect where a fault occurred first, either inside or outside the facility.
Galvanic separation and DC coupling: – Allows complete measurements on dissimilar power systems. For example troubleshoot UPS systems by simultaneously recording the battery voltage and power output.
Power quality and power load studies: – Assess baseline power quality to validate compatibility with critical systems before installation and verify electrical system capacity before adding loads.

Range (peak value): 280 mV
Nominal voltage (rms): 100 mV
Basic safety: 300 V CAT III
Input filter: Each channel is equipped with a passive low-pass filter, an anti-aliasing filter and a 16-bit A/D converter. All channels are sampled synchronously with a common quartz-controlled clock pulse. The filters protect against voltage transients and limit the signal rise rate, reduce high frequency components and especially the noise voltage above half the sampling rate of the A/D converter by 80 dB, thus achieving very small measuring errors in an exceptionally large amplitude range. This is also valid under extreme operating conditions like transient voltages at the output of converters.
Input capacitance: 5 pF
Input resistance: 1 MΩ
Overload capacity (rms): 1000 V, continuously
Number of inputs: 8 galvanically isolated inputs for voltage and current measurements.
Voltage rise rate: max. 15 kV / µs
Sensor safety: up to 600 V CAT IV depending on sensor
