⚡ Please Contact us via email or telephone to find out the current lead time ⚡

Use the Fluke 1760 to constantly log power quality information from 8 separate input channels (connect 4 current/4 voltage or up to 8 voltage channels simultaneously).

Designed for use out in the field, the Fluke 1760 is rugged and reliable enough to withstand any kind of environment and is designed to be left constantly logging power information over a time period directly onto an SD card that’s included as standard with the tester. This information can then be downloaded once testing is completed and interacted with further via the use of an included software package.

The 1760 is designed to log a comprehensive range of values, including voltage events (dips, swells and interruptions) and can constantly log total harmonic distortion, voltage and current harmonics up to the 50th/interharmonics, frequency, unbalance, flicker, kWh, power factor, power (P, Q and S), current and voltage (via the use of included flexible current probes and voltage probes).

Overview of Measurement Functions
Statistical Evaluation
 Power quality statistics according to EN50160 and DISDIP tables like ITIC, CEBEMA, ANSI
Event List
 Dips, swells and interruptions are detected and stored in the event list. Also any trigger which fires generates an event added to this list.
 The Event list shows the exact time when the event occurred as well as the duration and magnitude. Sorting by several attributes of these events is possible to select one for further root cause analysis.
 RMS values, transients and fast transients can be stored if a trigger fires.
Continuous Recording
 Fluke 1760 records rms values together with corresponding minimum and maximum values for:
 • Voltage
 • Current
 • Power P, Q, S
 • Power Factor
 • kWh
 • Flicker
 • Unbalance
 • Frequency
 • Harmonics/Interharmonics
 continuously with the following time aggregations:
 Day
 10 min
 Free Interval, e.g.: 15 min, 2h
Triggered Recordings
rms:  Aggregation time is adjustable between 10 ms (1/2 cycle), 20ms (1 cycle), 200ms (10/12 cycles) or 3 sec (150/180 cycles).
 Calculating rms values, Harmonics and Interharmonics is performed synchronous to the power frequency.
 Basic aggregation for harmonics and interharmonics is 200ms
Oscilloscope:  Sample rate is 10.24 kHz for all 8 channels
Fast Transients:  Sample rate is selectable from 100 kHz to 10 MHz for channel 1-4 FFT of Fast Transients
Mains Signalling
 Phases and N-conductor, Voltage and current
Online Mode
 Variable refresh rate. This feature allows verification of instrument set up and delivers a quick overview of oscilloscope, transients and events.

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.
